In this Brownells Tech Tip Video, Brownells gun tech Steve Ostrem explains what headspace is and why it’s one of the most critical measurements for nearly all firearms. Even if you’re an experienced rifle shooter, it’s worth watching this video to refresh your understanding of headspace measurements, and the correct use of “GO” and “NO-GO” gauges.
Headspace Definition
In firearms, headspace is the distance measured from the part of the chamber that stops forward motion of the cartridge (the datum reference) to the face of the bolt. Different cartridges have their datum lines in different positions in relation to the cartridge. For example, 5.56x45mm NATO ammunition headspaces off the shoulder of the cartridge, whereas .303 British headspaces off the forward rim of the cartridge. If the headspace is too short, ammunition that is in specification may not chamber correctly. If headspace is too large, the ammunition may not fit as intended or designed and the cartridge case may rupture, possibly damaging the firearm and injuring the shooter. (Source: Wikipedia)
Problems Caused by Too Much Headspace
Excessive headspace issues can include: light primer strikes, failure to fire, bulged/blown cases, case separations, split shoulders, or unseated primers after firing. Case ruptures caused by excessive headspace can lead to catastrophic failures causing serious injury. That is why headspace is such an important measurement.
Problems Cause by Too Little Headspace
Insufficent (or excessively tight) headspace can prevent the firearm from going into battery, resulting in failure to fire or deformation of the cartridge case. Various feeding and functioning problems can be caused by cases with too little headspace, even if a round can be chambered (with effort).
Headspace Gauges
Headspace is measured with a set of two headspace gauges: a “Go” gauge, and a “No-Go” gauge. Headspace gauges resemble the cartridges for the chambers they are designed to headspace, and are typically made of heat-treated tool steel. Both a “Go” and a “No-Go” gauge are required for a gunsmith to headspace a firearm properly. A third gauge, the “Field” gauge, is used (as the name implies) in the field to indicate the absolute maximum safe headspace. This gauge is used because, over time, the bolt and receiver will wear, the bolt and lugs compress, and the receiver may stretch, all causing the headspace to gradually increase from the “factory specs” measured by the “Go” and “No-Go” gauges. A bolt that closes on “No-Go” but not on “Field” is close to being unsafe to fire, and may malfunction on cartridges that are slightly out of spec. (Source: Wikipedia)
You need to understand Headspace Gauges and how to use them. There are “Go”, “No-Go”, and “Field” gauges. The “Field” is actually the longest. Brownells explains: “The GO gauge corresponds to the SAAMI minimum chamber length, while the FIELD gauge usually matches the maximum chamber depth, or slightly less. NO-GO gauges are an intermediate length between minimum and maximum, that, technically, is a voluntary dimension. A firearm that closes on a NO-GO gauge and does not close on a FIELD gauge may not give good accuracy and may have very short cartridge case life [.]”

A while back, Sinclair International’s Reloading Press Blog featured a “round-table” discussion of reloading techniques. Sinclair’s team of tech staffers were asked: “What do you feel is the one-most crucial step in precision reloading?”
Here are their responses (along with comments from our Editors):
Phil Hoham: “I feel that when working up a load do not go too high or too low in your powder charge. Stay away from ‘suggested loads’ you hear at the range, or on the internet. Always be sure to use a published reloading manual that presents not only minimums and maximums, but also pressure, velocity, and a proper range of powders used. Do not get distracted in the reloading process, and remain focused at all times during each step involved.”
AccurateShooter.com: Some loads presented on the Internet are OK as a starting point, but it is absolutely critical to understand that pressure maximums will vary considerably from one rifle to another (of the same chambering). For example, one 6mmBR rifle shooting 105gr bullets can max out with 30.0 grains of Varget powder, while another rifle, with the same chamber dimensions, but a different barrel, could tolerate (and perform better) with half a grain more powder. You need to adjust recommended loads to your particular rifle and barrel.
Pete Petros: “This could be a very broad topic, but if I were to pick one, it would be making sure to pay close attention, and weigh each and every powder charge to ensure that each load is exact and consistent. This is important not only for accuracy, but also for safety reasons.”
AccurateShooter.com: If you’re shooting beyond 200 yards, it is critical to weigh your loads with an accurate scale or automated system such as the AutoTrickler V3/V4. Loads that are uniform (within a few kernels) will exhibit lower Extreme Spread and Standard Deviation. And remember, even if you stick with the same powder, when you get a new powder lot, you may have to adjust your load quite a bit. For example, .308 Palma shooters have learned they may need to adjust Varget loads by up to a full grain from one lot of Varget to the next.
Ron Dague: “I feel that the most important step(s) in reloading for accuracy are in the initial case prep. Uniforming the primer pocket to the same depth to ensure consistency in primer seating is a crucial step. Additionally de-burring the flash holes, each in the same way to clean up and chamfer the inside is important. It ensures that the ignition from the primer is uniform and flows out in the same consistent pattern. Doing so will create uniform powder ignition and tighten up your velocity Extreme Spread.”
AccurateShooter.com: With some brands of brass, primer pocket uniforming and flash-hole deburring is useful. However, with the best Lapua, Norma, and RWS brass it may be unnecessary, or worse, counter-productive. So long as your Lapua brass flash-holes are not obstructed or smaller than spec, it may be best to leave them alone. This is particularly true with the small flash holes in 220 Russian, 6BR, and 6.5×47 cases. MOST of the flash-hole reaming tools on the market have cutting bits that vary in size because of manufacturing tolerances. We’ve found tools with an advertised diameter of .0625″ (1/16″) that actually cut an 0.068″ hole. In addition, we are wary of flash-hole deburring tools that cut an aggressive inside chamfer on the flash-holes. The reason is that it is very difficult to control the amount of chamfer precisely, even with tools that have a depth stop.
Rod Green: “I feel that bullet seating is the most important step. If you had focused on making sure all prior steps (case prep, powder charge, etc.) of the process have been carefully taken to ensure uniformity, bullet seating is the last step, and can mean all the difference in the world in terms of consistency. Making sure that the bullet is seated to the same depth each time, and time is taken to ensure that true aligned seating can make the load.”
Bob Blaine: “I agree with Rod. I strongly feel that consistent bullet seating depth is the most important step in creating the most accurate hand loads. I have seen the results in both my bench and long range rifles. Taking the time to ensure exactness in the seating process is by far, the number one most important step in my book.”
AccurateShooter.com: Agreed. When loading match ammo, after bullet seating, we check every loaded round for base of case to ogive length. If it varies by more than 3 thousandths, that round is segregated or we attempt to re-seat the bullet. We measure base of case to bullet ogive with a comparator mounted on one jaw of our calipers. You may have to pre-sort your bullets to hold the case-base to ogive measurement (of loaded rounds) within .003″.

Do you own or shoot an AR-platform “black rifle”? Then you know these rifles run dirty, and have some unusual maintenance requirements. On the other hand, the AR “Modern Sporting Rifle” is fun and versatile with a vast range of options among buttstocks, barrels, handguards, and grips. You can assemble a simple 16″ barrel .223 Rem rig for home defense, or build a long-barreled 6mm ARC rifle with bag-rider buttstock and high-magnification optic for long range target work. The choice is up to you.
To help with your black rifle journey, here are eight helpful videos from Brownells. These will help ensure your AR rifle cycles reliably and runs longer, with reduced wear. Brownells also explains how to choose the optimal barrel twist rate. CLICK HERE to order AR parts, accessories, and ammo from Brownells.
AR Bolt/Bolt Carrier Lubrication — Smarter Methods
This video shows the proper way to lubricate an AR-15 bolt-carrier assembly. The video identifies the key metal-on-metal friction points where you actually need lubrication: the rails on the underside of the carrier, shiny wear points on top, and just a dab on the cam pin. How much oil/lubricant should you use? The AR-15 is pretty forgiving on that point. Some spots work best with grease, others work best with a lighter oil. Just keep it out of the combustion areas. Those little holes in the carrier are gas vent holes, NOT oil holes!
AR Maintenance — General Cleaning Procedures
Let’s face it, ARs with the original gas system tend to run dirty. You’ll need to regularly clean the bolt carrier and bolt. In addition you should regularly clean the chamber area and the inside of the upper. Also make sure to clean the lower (see video 3:15) and ensure the trigger assembly is properly maintained. This video covers general cleaning and maintenance of AR-platform rifles. We highly recommend that all new AR owners watch this video. NOTE: When cleaning the bolt, don’t forget the extractor recess and ejector recess. The majority of ARs we’ve seen that did not function properly had gunk (lube, carbon, brass shavings) clogging these areas.
AR Barrel Twist Rates — What You Need to Know
AR barrels can be ordered with a variety of twist rates from 1:12″ to 1:7″. Basically, the longer/heavier the bullet you plan to shoot, the faster the twist rate you need. For example, Sierra recommends a 1:7″ twist rate for the 90gr SMK. A 1:12″ could work with the small lightweight bullets up to 55 grains. The 1:9″ barrel will stabilize the light and mid-weight bullets up to about 77 grains. We recommend a 1:8″ or 1:7″ twist rate for the best versatility. You’ll find a detailed discussion of AR twist rates on PewPewTactical.com.
How to Install an AR15 Trigger Assembly
One of the most common AR upgrades done by black rifle owners is swapping out the trigger for a better unit (perhaps a two-stage). Trigger replacements on ARs can be done fairly easily with basic tools. But there are some recommended procedures to ensure the trigger group swap goes easily. You’ll want to have a proper mount to secure the lower, and tools that fit the pin diameters on your lower.
AR Rifle Build — How to Avoid Common Mistakes
This Brownells video explains five common yet serious errors people make while assembling or modifying AR-15 class rifles. Here are the five mistakes all AR builders need to avoid:
1. Mounting Accessories that Contact the Gas Block: A common mistake is attaching accessories like bipods directly to the handguard in such a way that screws exert pressure on the gas block. This misalignment can harm accuracy. The solution involves carefully selecting the attachment point or opting for shorter screws.
2. Incorrect alignment of the Gas Block: This is another widespread issue. Properly aligning the gas block with the barrel’s gas port is essential for the rifle’s reliable operation. Misalignment can lead to cycling problems due to insufficient gas flow.
3. Over-Torquing the Castle Nut: Applying excessive torque to the castle nut can damage the threads of the receiver extension, also known as the buffer tube. The recommended torque setting is 40 foot-pounds. Exceeding this value can compromise the structural integrity of these components.
4. Excessive Material Removal in Upper Receiver Lapping: Removing too much material when lapping the upper receiver, can cause the barrel to sit too far into the upper receiver. This misplacement can affect feed ramp alignment and gas block positioning, potentially leading to functional issues.
5. Improper Buffer Tube Installation: Failing to install the buffer retainer and spring correctly, or screwing the buffer tube in excessively, can obstruct the upper receiver’s closure. Correct installation depth is crucial for these components to perform their intended functions.
Checking Headspace on ARs
In this Tech Tip, Brownells gun tech Steve Ostrem walks users step-by-step through the process of checking headspace on their AR-15 rifles, both new and used. It is very important to have proper headspace to ensure proper feeding and extraction, and to ensure good brass longevity (with less risk of dangerous case separation). Starting at 2:10, this video explains how to check headspace with go/no-go gauges and maximum headspace gauge. Ostrem notes: “If you have an AR that closes on a no-go gauge, we recommend taking it to a gunsmith before heading to the range.”
Excessive headspace in AR platform rifles can lead to dangerous case separation.
Setting Up Gas Tube Systems
This Tech Tip examines AR-platform gas systems, and shows how to select the proper length gas tube, and how to configure multiple tube systems if you change your barrel to different lengths. This is worth watching for anyone re-barreling an AR.
Barrel Gas Block Alignment — Key to Reliable Cycling
In this video, Brownells gun tech Steve Ostrem explains surefire methods to align your gas block. The most common problem with AR builds is poor cycling, commonly caused by misalignment between the gas block and the barrel’s gas port.

AR-platform rifles can be maintenance-intensive beasts. They need regular inspection, cleaning, and lubrication. But some AR owners make the situation worse by not regularly cleaning important small parts, or by using too MUCH oily/greasy lubricants in the wrong places. A properly maintained and lubricated AR15 can shoot hundreds of rounds (between cleanings) without a problem. If you learn where (and where not) to apply lubricant, you’ll find that your AR will run more reliably and the task of cleaning the bolt, bolt carrier, and upper receiver internals will be less of a burden.
Here we showcase videos that show how to field-strip an AR-15, inspect the key parts, clean components, and lubricate internal parts as needed. Along with these videos, we recommend you read the comprehensive AR-15 Gun Cleaning Clinic article on the Brownells website. This explains in detail important procedures that the videos might only cover in a few seconds.
If you want to keep your black rifle running smoothly and reliably, you must clean it regularly and follow the correct maintenance procedures. Here are five videos that explain how to properly disassemble and clean AR-platform rifles.
1. How To Clean Your AR-15 | Cleaning and Maintenance Tips
This is a quick 90-second starter video that may help new AR owners. Ricky Lehnhardt of OTIS Technology demonstrates the basics of cleaning and maintaining your AR-15. Lehnhardt does a good job identifying the points that need cleaning on the inside of ARs. However he works very quickly in the video. You may want to pause the video at some points. Also, Lehnhardt employs a cable for pulling patches and brushes through the barrel. Yes this is fast and easy. However, for match AR rifles, we recommend that you instead use a cleaning ROD with fitted bore guide.
2. Take-Down and Full Cleaning of AR-15 by Jerry Miculek
Here ace shooter Jerry Miculek takes down and cleans an AR-platform rifle belonging to his daughter Lena. This is a good video because Lena’s rifle was “run hard and packed up dirty” so you can see where carbon and grease build up. This 35-minute video is very thorough. Jerry is one of the nation’s top action carbine shooters, so listen carefully to his advice on cleaning and lubrication.
3. AR-15 Maintenance: Field-strip, Clean and Lubricate an AR-15
Gunsite Academy instructor and gunsmith Cory Trapp demonstrates the proper way to field-strip, clean, and lubricate an AR-15 carbine. In this 30-minute video, Trapp offers several important technical tips and hints. For example, at 11:05 Trap demonstrates how to determine if your bolt needs new gas rings. Along with cleaning procedures, this video explains how to inspect key components and how to function-test your AR before each shooting session.
4. AR-15 Dissassembly and Cleaning Guide
This video does a good job, with close-ups, showing how to remove the bolt carrier and clean the inside of the upper receiver. Then you can see how to work with various tools to clean the bolt, bolt carrier, and inside of chamber. We also recommend that you inspect the ejector recess and extractor recess. When we’ve inspected ARs that failed to cycle properly, we have often found nasty gunk (mixture of carbon, greasy lube, and brass particles) in these areas.
5. Basic AR-15 Quick and Easy Field Maintenance
In this NSSF-sponsored video, pro shooter Ryan Muller demonstrates basic, quick field maintenance of his AR-15. This would be for a quick cleaning and lubrication of the reciprocating parts. This covers rapid maintenance in the field. For full field-stripping and thorough cleaning, watch the previous videos.
Handy Mat for Cleaning AR Rifles
When working on an AR-15, it’s smart to have a pad that can absorb solvents and cushion your upper and lower. The $24.99 Real Avid Smart Mat is a good choice. This features printed take-down instructions and it has a handy parts tray on the right side. The mat rolls up for convenient storage. Click HERE to learn more.
Vital Inspections You Should Do After Disassembly
Last but not least, here are recommended inspections you should do every time you do a full field-strip and cleaning of your black rifle:

Here we showcase videos that show how to field-strip an AR-15, inspect the key parts, clean components, and lubricate internal parts as needed. Along with these videos, we recommend you read the comprehensive AR-15 Gun Cleaning Clinic article on the Brownells website. This explains in detail important procedures that the videos might only cover in a few seconds.
If you want to keep your black rifle running smoothly and reliably, you must clean it regularly and follow the correct maintenance procedures. Here are five videos that explain how to properly disassemble and clean AR-platform rifles.
1. How To Clean Your AR-15 | Cleaning and Maintenance Tips
This is a quick 90-second starter video that may help new AR owners. Ricky Lehnhardt of OTIS Technology demonstrates the basics of cleaning and maintaining your AR-15. Lehnhardt does a good job identifying the points that need cleaning on the inside of ARs. However he works very quickly in the video. You may want to pause the video at some points. Also, Lehnhardt employs a cable for pulling patches and brushes through the barrel. Yes this is fast and easy. However, for match AR rifles, we recommend that you instead use a cleaning ROD with fitted bore guide.
2. Take-Down and Full Cleaning of AR-15 by Jerry Miculek
Here ace shooter Jerry Miculek takes down and cleans an AR-platform rifle belonging to his daughter Lena. This is a good video because Lena’s rifle was “run hard and packed up dirty” so you can see where carbon and grease build up. This 35-minute video is very thorough. Jerry is one of the nation’s top action carbine shooters, so listen carefully to his advice on cleaning and lubrication.
3. AR-15 Maintenance: Field-strip, Clean and Lubricate an AR-15
Gunsite Academy instructor and gunsmith Cory Trapp demonstrates the proper way to field-strip, clean, and lubricate an AR-15 carbine. In this 30-minute video, Trapp offers several important technical tips and hints. For example, at 11:05 Trap demonstrates how to determine if your bolt needs new gas rings. Along with cleaning procedures, this video explains how to inspect key components and how to function-test your AR before each shooting session.
4. AR-15 Dissassembly and Cleaning Guide
This video does a good job, with close-ups, showing how to remove the bolt carrier and clean the inside of the upper receiver. Then you can see how to work with various tools to clean the bolt, bolt carrier, and inside of chamber. We also recommend that you inspect the ejector recess and extractor recess. When we’ve inspected ARs that failed to cycle properly, we have often found nasty gunk (mixture of carbon, greasy lube, and brass particles) in these areas.
5. Basic AR-15 Quick and Easy Field Maintenance
In this NSSF-sponsored video, pro shooter Ryan Muller demonstrates basic, quick field maintenance of his AR-15. This would be for a quick cleaning and lubrication of the reciprocating parts. This covers rapid maintenance in the field. For full field-stripping and thorough cleaning, watch the previous videos.
Handy Mat for Cleaning AR Rifles
When working on an AR-15, it’s smart to have a pad that can absorb solvents and cushion your upper and lower. The $24.99 Real Avid Smart Mat is a good choice. This features printed take-down instructions and it has a handy parts tray on the right side. The mat rolls up for convenient storage. Click HERE to learn more.
Vital Inspections You Should Do After Disassembly
Last but not least, here are recommended inspections you should do every time you do a full field-strip and cleaning of your black rifle:

Brownells is a well-known retailer of guns, gun parts, tools, accessories, ammo, and pretty much everything gun-related. What you may not know is that Brownells has a very active video production department that releases new “how-to” and product information videos every week. These videos offer helpful advice on gun cleaning/maintenance, reloading, as well as selecting/assembling components for various kinds of rifles. And every week Brownells serves up a new products video. There now over 1000 videos on the Brownells YouTube Channel, which is truly a remarkable resource.
Here are six of our favorite videos from Brownells. There’s a helpful guide to scope installation, AR owners will find some good advice on spare parts, new reloaders can learn how to use the OAL tool, and all gun owners should watch the video on ammunition storage.
Scope-Mounting — Common Mistakes to Avoid
Always be careful when mounting a rifle scope. This isn’t a super-complex or highly technical task, but there are ways you can mess it up. This video explains common pitfalls to avoid when mounting a scope.
1. Make sure the rings don’t touch ANY part of the turret housing, objective bell, or eyepiece.
2. Be certain the scope rings are tightly clamped to the scope base. Grasp the scope with one hand and the rifle with the other, then ensure there is no play.
3. Make sure there’s clearance between the objective bell and the rifle. No part of the scope should touch the rifle itself.
4. NEVER over-tighten the scope rings. You can actually crush the scope tube and damage the optic beyond repair. Stick to the torque specs!
How to Use Hornady OAL Tool and Hornady Bullet Comparator
Gun Tech Steve Ostrem explains how to properly use Hornady’s Overall Length Gauge to determine length-to-land precisely. The OAL Gauge uses a “Modified Case” that threads onto the tool and holds a bullet. Push on the back of the gauge until you feel the bullet just touch the rifling. (We do this gently at first, tapping the rod a couple time to ensure the bullet is aligned correctly). Once you’ve got the length, then use the tool with a comparator on your calipers to get the length-to-lands. NOTE: We recommend taking the measurement 3-4 times in a row to get a reliable number. With a little practice your should be able to get repeatable measurements within .0015″.
Air Travel with Firearms — Key Regulations You Must Follow
You can travel on commercial airlines with firearms. But you must follow the TSA regulations, and your particular airline’s rules. First, make sure your guns are UNLOADED before your leave home. Guns need to be carried in proper hard-sided cases that cannot be pried open. Be prepared to unlock the case if the TSA wants to inspect what’s inside. TSA agents can cut the locks if they need to open the case but can’t locate you. If you use special TSA-approved locks, TSA agents have master keys that let them open the case without destroying your locks. You CAN transport up to 11 pounds of ammunition — with restrictions explained in the video.
How to Store Ammunition Safely and Securely
This has been one of the most popular Brownells videos — with over 1.7 million views. Here’s the deal — ammunition WILL keep for a long time if you store it properly. DO store ammunition in a cool, dry place that doesn’t have wide temperature swings. Temperature cycling will also degrade primers and powder. Put it in airtight ammo cans to keep out the moisture. Tupperware containers will work too. Brownells also recommends putting moisture-absorbing silica packs in your ammo containers. DON’T just keep ammo in factory cardboard factory boxes stacked in the basement, attic, or garage (especially on the floor). Factory ammo boxes can absorb moisture which can degrade primers and corrode the brass cases. Yes, sealed military ammo will usually handle this kind of storage for quite a while, but it’s still not wise.
Must-Have Spare Parts for AR-Platform Rifles
In this video, two knowledgeable gun techs answer the question: “What spare parts should I keep on hand for my AR-15?” On the list are: Gas Rings, Buffer Spring, Extractor Spring and Pin. NOTE: You may want to try the one-piece spiral gas ring rather than the standard rings which require alignment. The cotter pin and cam pin can also easily get lost when the Bolt Carrier Group is disassembled for cleaning. On the lower receiver you’ll want spare springs and detents for the pivot/takedown pins. If you’re using lighter-power springs, keep standard-power spares on hand. If your rifle stops working, swap in the factory-spec springs to find out if the problem is the gun or your ammo. Also, if you have upgraded your trigger, always keep the original trigger as a backup.
Cleaning Advice for .22 LR Rimfire Rifles
Gun Techs Steve Ostrem and Caleb Savant debunk some myths about cleaning .22 LR barrels. One myth is that cleaning will harm the accuracy of a .22 LR barrel. Caleb thinks this myth is the result of people cleaning a barrel from the muzzle and damaging the muzzle crown, which CAN diminish accuracy. If it’s done right, cleaning won’t damage the bore. However, you certainly do NOT have to clean your 22 LR’s bore every time you go to the range. But DO clean the action every time you shoot the rifle, especially on a semi-auto. What about shooting a lot of lead bullets? Won’t that lead up the bore? The guys give us the straight skinny on lead fouling, too. When you see your .22 LR rifle’s groups opening up, you may want to consider cleaning.
