Today’s video showcase covers bore-sighting methods and technology. Bore-sighting the old-fashioned way — by looking down the bore of a rifle at a target — is not difficult. With a conventional bolt-action rifle, visual bore-sighting can be done quickly and easily. Rest your gun securely on bags, remove your bolt and set up a 50-yard target with a large bright orange or black center circle. Look through the back of the action and you should be able to sight down the bore with your own eyes just fine. There’s no need for expensive hardware. In fact it may be easier to bore-sight the “old-fashioned way” rather than try to see a laser in bright sunlight at 50 yards (or even 25).
However, with lever guns and semi-auto rifles, including the popular AR15, M1 Garand, and M1A, the design of the receiver may make it virtually impossible to sight down the bore with the naked eye. That’s where a modern laser bore-sighting device comes in handy. For those situations where a bore-sighting tool is needed, we recommend a laser bore-sighter that fits inside your chamber. An in-chamber laser device, as shown below, is handy and has less safety risk than a tool which fits in the end of the barrel.
How to Bore-Sight Your Rifle in Five Minutes
This video from Australia shows the basics of the bore-sighting process. First set up a target 50 yards (or closer) from your shooting station. Make sure the rifle is well-supported and stable. When the target is ideally centered in the BORE of the barrel, then adjust the reticle on your scope to center the crosshairs on the middle of the target. Then, after checking down-range, take a few test shots. Finally, move the target out to 100 yards and confirm your zero, as explained at the close of today’s article.
Vortex Shows How to Bore-Sight Rifles
This well-made, informative video from Vortex covers the basics of bore-sighting. Bore sighting your rifle is a simple way to establish an initial zero to get you on target faster and save you ammo at the range. Thankfully, it doesn’t take a ton of gear or ammunition to bore-sight a rifle effectively. Video host Jimmy from Vortex provides a handy, step-by-step guide in this 10-minute video.
Bore-Sighting Using a Barrel-Mounted Laser Bore-Sighter
If you wondered why a barrel-mounted laser bore-sighter was off-center? Or if you want to learn how to use one properly, this video shows how to safely and properly zero a scope using a barrel-mounted laser bore sight device. Another option is a small cartridge-sized laser that fits inside the chamber. These sell for under $25.00 and are convenient. There are safety advantages to in-chamber lasers.
Initial Bore-Sighting at Home (Before You Head to the Range)
This useful video shows how to bore-sight a rifle at home. This can save time (and money for ammo) when you do get to the range to confirm your scope’s zero. This home procedure works best if the target is well-illuminated while the rifle is in a shadowed area, creating the best contrast. Also make sure the rifle is on a steady support — such as a portable gun vise or sandbags front and rear.
Bore-Sighting with a Red Dot (Reflex) Sight
As with conventional scopes, if you have a red dot sight or reflex optic, you’ll need to bore-sight your rifle, then zero the optic. [Reflex sights use a reflex lens to project a dot or reticle onto the target, whereas red dot sights use a flat, reflective surface to display a red dot reticle.] In this video, retired Navy SEAL Mark Cochiolo demonstrates how to bore-sight then adjust a red dot. Bore sighting allows you to zero your red dot so that your shots hit near your intended point of impact.
Learn More about Bore-Sighting with Tools
To learn more about bore-sighting, you can view a detailed article on the Warne Scope Mounts website. This features through-the-barrel images and discussion of tools that fit in the chamber or barrel to project a laser beam down-range. Shown below are cartridge-sized projecting lasers that fit in a rifle’s chamber. These are available for a wide variety of cartridge/chamber sizes.
WARNING: If you use an in-barrel laser be sure to remove it BEFORE chambering a round. ANY obstruction in the barrel can cause serious injury or even death if you fire a round.
Bore Sight Grid Tool with Arbors
The Bushnell Bore Sight with Arbors is a bore-sighting tool that many gun stores and gunsmiths use. This device uses arbors but does not transmit a laser.
You attach the tool to the end of the barrel and align it with your scope. A grid is visible inside the bore-sighter. Look at that grid and then and align your scope’s reticle with the grid. This Bushnell unit ships with three expandable arbors in 22-270 caliber, 7mm-35 caliber, and 35-45 caliber.
How to Zero a Hunting Rifle Efficiently
Once you have bore-sighted your rifle to get “on target” successfully, then you want to zero your optic so that the shot falls exactly where you want it at your target distance, typically 100 yards. This Vortex video shows you how to quickly and efficiently sight-in and zero a hunting rifle before heading out into the field. This video explains a simple procedure that lets you get a solid zero in just three shots. Of course you probably want to fire a few more rounds to confirm your zero before you head off to your hunting grounds, but this will let you get on-target with a minimum amount of time and ammo expended. This helpful video now has 3.2 million views on YouTube!
Fouling Shots and Cold Bore Condition
If you recently cleaned your rifle, you may want to fire two or three fouling shots before you start this procedure. But keep in mind that you want to duplicate the typical cold bore conditions that you’ll experience during the hunt. If you set your zero after three fouling shots, then make sure the bore is in a similar condition when you actually go out hunting.

Rifle accuracy is pointless unless you can see your target and aim precisely. That’s why good optics are so important for precision shooting — from 50 yards out to a mile and beyond. Top quality scopes can be very expensive — you’ll see optics costing $3000 or more on many competition F-Class and PRS rifles. Today’s video showcase covers important “Riflescope Knowledge”, including how to adjust for parallax, and how to properly sight-in your scoped rifle. In addition there’s a helpful video defining Minute of Angle (MOA) plus videos showing how to mount optics correctly (and avoid common scope-mounting mistakes).
Rifle Sight-In Process — Start to Finish
Here Ryan Cleckner shares his process for sighting in a scoped rifle. This helpful video covers the full process: bore-sighting, 25-yard shot confirmation, shooting groups, making adjustments at 100 yards, and finding mechanical zero. Looking for more valuable rifle instruction? Then check out Ryan Cleckner’s book, Long Range Shooting Handbook.
How to Adjust for Parallax
Most precision rifle scopes have parallax adjustment, but what is it and why do you need to adjust it? In this Shooting USA video, John Paul of JP Rifles defines parallax and explains why you need to set parallax correctly for the distance to your target. The video then show how to adjust parallax correctly, a process which should start with the scope’s ocular focus.
Understanding Minute of Angle (MOA)
In this video, Ryan Cleckner explains the measurement term “minute of angle” (MOA) and how to use MOA adjustments on your scope to compensate for bullet drop at varying distances. MOA is an angular measurement, used often in long range shooting, that is 1/60th of one degree of a circle. One MOA represents 1.047″ at 100 yards and 10.47″ at 1000 yards. Want to learn more? Read Ryan Cleckner’s article Understand and Using Minute of Angle.
Scope Mounting: Common Scope-Mounting Mistakes To Avoid
Mounting a scope isn’t a super-complex or highly technical job, but there are ways you can mess it up. This Brownells video explains common pitfalls to avoid when you’re mounting a rifle scope.
1. Make sure the rings don’t touch any part of the turret housing, objective bell, or eyepiece. Any one or combination of those will throw off your shot groups big time. Make sure those rings are clamping ONLY the scope’s main tube.
2. Ensure that the scope rings are properly clamped to the scope base. If you can grasp the scope with one hand and the rifle with the other and there’s play between them, your groups are going to be all over the place! Scope rings come with torque specs for a reason.
3. Make sure there’s clearance between the objective bell and the rifle. No part of the scope should touch the rifle itself. The only nexus between the scope and the rifle should be the scope rings — and they’re not actually part of the rifle. This also applies to a removable lens cover. When it’s on the scope, it should not touch any part of the gun.
4. Don’t mount the scope too low on an AR-15. On most rifles, you do want the centerline of the optic as close to the bore as you can get it. But the AR-15’s stock is on almost the same plane as the top of the receiver, so you need some height on the scope. Otherwise, it’ll be too low for you to look through it.
5. Overtightening the scope rings is VERY BAD. You can actually crush the scope tube and damage the optic beyond repair. Stick to those torque specs! If the rings come with a little wrench, that wrench is all you need to tighten them.
How to Sight In a Riflescope — Vortex Tech Talk
This popular video from Vortex Optics explains how to sight-in a rifle so that the reticle is aligned correctly and the scope is zeroed properly for your intended application/discipline. People need to remember that the sight height established by the rings will affect their zero, as the centerline of the scope is above the centerline of the barrel.
Scope Mounting — Proper Alignment and Torque Values
An improperly installed scope can cost you points at a match. In this video, MDT Pro Shooter Keith Baker explains the simple steps required to ensure your scope is secured properly with the reticle aligned correctly. The video centers on a typical Precision Rifle optics installation, but the techniques will also work for hunting, varmint, and benchrest rifles.

For decades, Shooting USA has been a leading video resource for the shooting sports and hunting. This popular cable TV show covers shooting matches, and provides expert information on precision shooting, gun maintenance, optics, and defensive firearms use. Here are five interesting videos all worth watching. Learn about wind-reading, gun maintenance, and optics.
1. Reading the Wind — SGT Sherri Jo Gallagher of USAMU
Sergeant Sherri Jo Gallagher formerly of the U.S. Army Marksmanship Unit (USAMU) shows us how to read the wind in given conditions, and how to apply your wind assessment when aiming down-range. During her time with the USAMU, Sherri won the National High Power Championship, and was the first woman in history to earn the U.S. Army “Soldier of the Year” honors. Sherri comes from a legendary family of shooters — she was raised by Ace Marksman Mid Tompkins and mother Nancy Tompkins, the first female to win the NRA National High Power Championship.
2. Field-Stripping and Cleaning AR-Platform Rifles
Let’s face it — Black Rifles run dirty. On AR-platform rifles, the gas system blows carbon and powder residues back into the action and bolt carrier group. Accordingly, you need to clean ARs early and often, and you should fully disassemble the bolt carrier to access parts and recesses which accumulate greasy lube and hard carbon. This helpful video shows how to field-strip and clean AR-platform rifles. If you own an AR, this is definitely worth viewing. With over 2.7 million views, this is the second most-watched video on Shooting USA’s YouTube Channel.
2. MOA Defined — Jim Scoutten Explains Minute of Angle
Minute of Angle (MOA) — this is the most common measurement of group size, and hence rifle accuracy. You hear about shooters hoping to shoot 1 MOA or “half-MOA”, but many folks could not give you a precise definition. In fact MOA is an angular measurement that equates to one-sixtieth of one degree of Arc. In this video, host John Scoutten defines MOA. He then demonstrates how MOA translates to accuracy on target. He demonstrates one-half-MOA accuracy with a Les Baer Custom rifle. This company offers a three-shot, half-MOA guarantee for its rifles.
4. How to Adjust for Parallax
Most precision rifle scopes have parallax adjustment, typically a knob on the left side of the scope. but what exactly is “Parallax” and why do you need to adjust optics to ensure the parallax setting is optimal? In this Shooting USA video, John Paul of JP Rifles defines parallax and explains why you need to set parallax correctly for the distance to your target. The video then shows how to adjust parallax correctly, a process which should start with the scope’s ocular focus.
5. How to Mount a Riflescope
When mounting a scope you want to use quality rings, and ensure that the scope is leveled properly. In addition, you need to adjust the fore/aft position of the scope so that eye relief is correct. Ideal scope position may be different when shooting from the bench vs. shooting prone. In this Shooting USA video John Paul of JP Rifles reviews scope mounting basics.
Share the post "Watch and Learn — Five Great Shooting USA Videos"
In this video, former Army Ranger sniper team leader Ryan Cleckner explains how proper head and scope position is a critical component to accurate shooting. Ryan finds that some shooters place the scope too far forward or too far rearward. If the scope is too far back you may have issues with eye relief and stock reach to shoulder. If it is too far forward, you may have cheek-weld problems or get neck strain. Cleckner cautions: “When you are in a good prone position, you don’t want any strain in your neck muscles or back.”
In the video, Cleckner offers a simple method to check your scope position:
“To see if your scope is set up properly … close your eyes, lay your head on your gun, get completely comfortable, and only when you are set-up, then open your eyes. If you can’t see clearly through your scope, CHANGE something [such as comb height or scope position]”.
“When you open your eyes, if you see some scope shadow [i.e. the black ring around the edge of the scope picture], figure out which way you need to move your head to get rid of that shadow, and then make adjustments to either your position, the rifle, or the scope.”
“Very often you’ll open your eyes and realize you need to move further back or further forward. Instead of moving your position [or head], move the scope and get it set up properly.”
Tip on Viewing Your Reticle:
Cleckner: “Sometimes it can be difficult to focus between the target and the reticle, even with the parallax adjusted properly. I recommend you focus only on the reticle. Just like the front sight on a rifle or a handgun, that reticle is what you can control, and it’s what matters. Focus on a crisp, clear reticle, in a stable platform, and all that’s left is trigger control.”
Long Range Shooting Handbook — A Good Resource
Cleckner’s Long Range Shooting Handbook covers a wide range of topics important for precision marksmanship — both shooting skills and technical matters. You can view Sample Chapters from Ryan’s Book on Amazon.com. Cleckner’s book is designed as an intro to key concepts such as MOA vs. Mils, External Ballistics, and Environmental Effects. Included are personal tips and advice based on Cleckner’s years of experience as a sniper instructor and special operations sniper.
The Long Range Shooting Handbook is divided into three main categories: What It Is/How It Works, Fundamentals, and How to Use It. “What It Is/How It Works” covers equipment, terminology, and basic principles. “Fundamentals” covers the theory of long range shooting. “How to Use It” gives practical advice on implementing what you’ve learned, so you can progress as a skilled, long range shooter.
Ryan Cleckner was a special operations sniper (1/75 RGR) and he served as a U.S. Army sniper instructor. Currently he works as a firearms industry executive and practicing firearms attorney.

Hunting season is underway now in many states. That means it’s time to inspect all your hunting gear, including your scope set-up. If you have a new optic, you’ll want to get it mounted correctly on your current rig. And if you have a new hunting rifle, you’ll need to mount the properly rings and install the riflescope so that you have the correct eye relief.
A proper scope installation involves more than just tensioning a set of rings — you need to consider the proper eye relief and head position, and it should be leveled correctly. This video shows a simple, quick method to mount a scope. The method assumes that the reticle (cross-hairs) are square without the turret. You’ll want to confirm that with a plumb line hanging straight down, a procedure you can do indoors.
In this NSSF video, Ryan Cleckner shows how to set up a scope on a hunting or tactical rifle. Ryan, a former U.S. Army Sniper Instructor, notes that many hunters spend a small fortune on equipment, but fail to set up their rifle to use the optics optimally. Cleckner likens this to someone who owns an expensive sports car, but never adjusts the seat or the mirrors.
Ryan notes that you want your head and neck to be able to rest naturally on the stock, without straining. You head should rest comfortably on the stock. If you have to consciously lift your head off the stock to see through the scope, then your set-up isn’t correct. Likewise, You shouldn’t have to push your head forward or pull it back to see a clear image through the scope. If you need to strain forward or pull back to get correct eye relief, then the scope’s fore/aft position in the rings needs to be altered. Watch the full video for more tips.
Tips on Mounting Your Scope and Adjusting Your Comb Height:
1. Normally, you want your scope mounted as low as possible, while allowing sufficient clearance for the front objective. (NOTE: Benchrest shooters may prefer a high mount for a variety of reasons.)
2. Once the scope height is set, you need to get your head to the correct level. This may require adding an accessory cheekpad, or raising the comb height if your rifle has an adjustable cheekpiece.
3. Start with the rifle in the position you use most often (standing, kneeling, or prone). If you shoot mostly prone, you need to get down on the ground. Close your eyes, and let you head rest naturally on the stock. Then open your eyes, and see if you are too low or too high. You may need to use a cheekpad to get your head higher on the stock.
4. If your scope has a flat on the bottom of the turret housing, this will help you level your scope. Just find a flat piece of metal that slides easily between the bottom of the scope and the rail. Slide that metal piece under the scope and then tilt it up so the flat on the bottom of the scope aligns parallel with the flats on the rail. Watch the video at 8:40 to see how this is done.
