What happens when a round goes off unsafely in an AR? Watch this video and see. At about the 00:40 time-mark the shooter has a malfunction (click no bang), with a round. He then removes the magazine, and clears the chamber (we think). On the next round, at 00:53 you hear a “Bang” and see a big puff of smoke coming out of the upper receiver (see photo at right). This has been called a “detonation” by the video-maker, but we’re not 100% sure what happened. What do you guys think? Watch the video carefully, and state your conclusions in the comment section if you wish.
What Caused this Malfunction? Watch Video…
In any event, the shooter is fortunate his upper did not completely fracture, launching shrapnel into his face or other body parts. This could have turned out much worse. Here are screen-shots from the video, showing details of the gun after the accident, along with the recovered brass case, which separated near the case-head.
Never had a chance to hunt prairie dogs in the American west? Then check out this video. Dan Eigen, host of the We Love It Outdoors Television series, ventured to South Dakota for some varmint hunting. Dan teamed up with Varmint Hunter Association President Jeff Rheborg to patrol some South Dakota Dogtowns where things get serious. In the video, you’ll see p-dog hits at distances from 70 yards to roughly 450 yards. The hunters were shooting from portable, wood-topped swivel rests, using AR-platform rifles on X-type sandbag rest. (Rifle zeroing session is shown at the 5:30+ mark.)
Multiple cameras were employed so you can see both the shooter’s POV and close-ups of the prairie dogs downrange. Watch the shooters having fun with a prairie dog cut-out and some Tannerite at the 9:00-minute mark. This guys are having a grand old time sending critters to Prairie Dog Heaven — we think you’ll enjoy the video.
Prairie Dog Hunting Starts at 2:20 Time-Mark in Video:
NOTE: This video actually covers three sequences: 1) Three-gun training; 2) Prairie Dog Hunting; and 3) Coyote Hunting. The Prairie Dog segment runs from 2:20 to 15:15. If you wish, you can slide the controls forward or back to watch the other segments.

In an unprecedented move, the central government of Canada, without parliamentary vote or debate, has banned a vast number of rifles, including most modern mag-fed, semi-auto rifles currently for sale. This action banning the firearms was done by Prime Minister Justin Trudeau via “Order-in-Council”, with no political debate and no vote of elected representatives. It was essentially an Executive action, rule by fiat, like a decree issued by a dictator.
Starting now, around 1,500 models of long-arms have become illegal to sell, transport, import or use in the Canada, according to CBC News.
“The government implemented the ban immediately, and without the need for legislation in Parliament, by reclassifying about 1,500 firearm models as prohibited. In the meantime, a two-year amnesty is now in effect for Canadians who own the banned firearms and government officials said gun owners will also have the option to be ‘grandfathered’ in with weapons they currently own, although no details were available for that program yet”. Source: NationalPost.com
Nova Scotia Killer Posed as Police Officer
This action came in response to the Nova Scotia killings by a madman, Gabriel Wortman, who dressed in a police uniform and used vehicles with law enforcement markings and lightbars. Wortman was NOT licensed to possess his weapons and had obtained his firearms illegally. According to Global News: “During the shooting, the gunman was traveling in a replica police vehicle and wearing an authentic police uniform.”
Canadian Investigators said Gabriel Wortman had several semi-automatic handguns and at least two semi-auto rifles, which may have been AR-type rifles, but we are not certain about the exact configurations of Wortman’s long guns. Notably, most if not all of Wortman’s guns were already ILLEGAL for Wortman to own under existing Canadian laws. The crazed shooter had violated multiple firearms laws already on the books, and did NOT possess his weapons legally (it is believed he sourced them from outside Canada). AR-type rifles required a special permit in Canada. And of course he violated multiple laws in impersonating a law enforcement officer.
Trudeau Exploits Nova Scotia Shooting to Ban Guns without Normal Legislation
Prime Minister Trudeau used the Nova Scotia mass killing as the impetus to fulfill his campaign promises to ban so-called “assault-type” weapons. Seven months ago, Trudeau pledged to ban modern semi-auto rifles, which he called “assault rifles”. Trudeau opportunistically leveraged the mass shooting to execute his plan with no public debate and no vote by elected officials.
Trudeau’s actions were criticized by many in Canada. Conservative Leader Andrew Scheer declared: “Taking firearms away from law-abiding citizens does nothing to stop dangerous criminals who obtain their guns illegally”. Alberta Premier Jason Kenney stated: “Today’s order does little to target criminals … instead, Ottawa is singling out law-abiding gun Canadians who purchased their property legally”. And Alison de Groot, Director of the Canadian Sporting Arms and Ammunition Association, said Trudeau’s gun ban “will strand somewhere between $200 to $300 million worth of pre-paid merchandise in stores”. READ MORE.
Q: Would a Ban on Semi-Auto Rifles Have Prevented the Nova Scotia Tragedy?
A: No. The killer Gabriel Wortman also used pistols, and could have been just as deadly with a pump shotgun. And nine of the 22 killed “died in house fires” set by Wortman. (Source: RCMP per Reuters.) Remember that fact — 40% of the victims were burned to death: “Of the 22 people killed, 13 were shot and nine died in house fires.” Source: CNN.com.
The real reason for the high kill count was that Gabriel Wortman was an insane maniac wearing a police uniform and driving a police car. The important questions to ask are how did he get the uniform and why were vehicles sold complete with police markings?
Terms of Canada’s Broad New Gun Ban
Under the Canadian gun ban, owners of prohibited firearms now have two years to turn in their rifles. According to CTV News: “Owners will also have the ability to be compensated through a buyback program, though the details of these options have yet to be outlined. Gun owners must be in compliance with the law by April 2022. Those who have not disposed of any banned firearms by that time may face sanctions under the Criminal Code.”
Was Trudeau’s massive gun ban necessary? Consider this comment from a Canadian gun owner: “Handguns and AR15s in Canada [were] highly regulated already. To get the license you go through a 2-day course. There was a 3- to 6-month wait for your application. Spouse must sign. No history of metal disorders. [Authorities conduct] phone interviews with credible people who know you. When you get your licence you must join a shooting club[.] Now you have your restricted license … and a government issued travel licence.”
Here is a list of all the firearms that have been banned (without Parliamentary vote) by Trudeau’s government. This includes AR15-platform rifle, AR10 rifles, Ruger Mini-14s, Semi-Auto M14-type rifles, and many other varients. Some big bolt-action guns will banned as well. ELR Researcher notes: “Read down to section 96: ‘Any firearm capable of discharging a projectile with a muzzle energy greater than 10,000 joules[.]’. Well 10,000 joules is 7375 foot-pounds, meaning [this would ban] ALL firearms chambered for most commercially-available .408 CheyTac, .416 Barrett, and .50 BMG ammo.”

As folks are stuck at home with the Pandemic lock-downs, many guys are thinking about projects involving their AR-15s sitting in their safes. We’ve seen some threads in our Forum asking about the .224 Valkyrie, an AR-centric cartridge that offers significantly better long-range performance than the .223 Remington (5.56×45). If you own a .224 Valkyrie, or are thinking about adding a .224 Valkyrie upper to your MSR (Modern Sporting Rifle) arsensal, here is load information from industry leaders Hodgdon and Sierra.
With the 90gr SMK (or similar High-BC projectiles), the .224 Valkyrie offers ballistics similar to the 6.5 Creedmoor but with significantly less felt recoil.
Hodgdon has reloading data for the .224 Valkyrie, a popular new cartridge optimized for the AR15 platform. “At Hodgdon, we’ve been researching this cartridge since before its introduction and are excited to release load data for the Valkyrie featuring powders like Hodgdon CFE 223, IMR 8208 XBR, and Hodgdon Varget” reports Ron Reiber, Hodgdon product manager/ballistician. Access the .224 Valkyrie Data via Hodgdon’s Reloading Data Center.
While new load data will continue to be updated, there is currently data for 80 different loads with bullet weights ranging from 50 to 90 grains. NOTE: The load data covers Hodgdon, IMR, and Winchester brand powders only. See Sierra Data for other powder brands. Bullet brands included are: Federal, Hornady, Nosler, Sierra and Swift.
About the .224 Valkyrie Cartridge
Basically a 6.8 SPC necked down to .22, the Valkyrie has a shorter case than the .223 Remington (and 5.56×45 NATO). This allows you to load the longest, heaviest .224-caliber bullets and still feed reliably from an AR15-type magazine. Designed to rival the .22 Nosler while still running well in ARs, the .224 Valkyrie offers excellent long-range performance when loaded with modern, high-BC bullets. We expect some bolt-action PRS shooters might adopt the .224 Valkyrie. Why? Reduced recoil. With the 90gr SMK, the .224 Valkyrie offers ballistics similar to the 6.5 Creedmoor but with significantly less felt recoil.
The new .224 Valkyrie has already developed a loyal following: “Shooting heavier bullets in an AR-platform rifle that maintain supersonic speeds beyond 1,300 yards has captured the interest of shooters and handloaders everywhere” — Hodgdon Powders
Our friend Gavin Gear of Ultimate Reloader.com found a superbly accurate load with Berger 80.5gr bullets.
IMPORTANT: Check Out Sierra’s .224 Valkyrie DATA
Sierra Bullets has also published extensive load data for the .224 Valkyrie. This covers over a dozen powder types — many more than the Hodgdon database. Sierra’s .224 Valkyrie load data covers projectiles from 50 grain all the way up to 95 grains. With the 90 to 95 grain bullets, the little Valkyrie can give 6mm match cartridges a real run for their money — offering similar ballistics with less recoil. When selecting a barrel for the long .224-cal bullets, specify a fast enough twist rate: “Sierra recommends a 1:6.5″-twist barrel for the #9290 22 cal 90 gr HPBT bullet. However, for cartridges like the Valkyrie, that can push them over 2650 fps muzzle velocity, a 1:7″-twist barrel will stabilize the bullet correctly.”
Here’s a radical new rifle. Instead of a vertical trigger that moves rearward when pulled by the index finger, this Blackwater T.O.R. A1 rifle has a lever INSIDE the lower receiver. That lever is moved by the operator’s THUMB, causing the rifle to fire. The claimed benefits of the “thumb-gun” are: 1) Improved Ergonomics (thumb stays in alignment with point of aim); 2) Better Mechanics (thumb is strongest digit and can manipulate lever easily); 3) Enhanced Safety (trigger blade/lever is not exposed).
This AR-type rifle was developed by Iron Horse, now partnered with Blackwater Worldwide. The new T.O.R. (aka “Thumb Operated Receiver”) A1 is the industry’s first AR-platform rifle incorporating patent-pending, lever-driven fire technology.
Iron Horse A1 Precision Rifle
The manufacturer has made some interesting claims about this new thumb-lever system. Blackwater/Iron Horse claims that “Multiple samples of users show a shorter learning curve and reduced shot group size”, and that the design “lends to greater accuracy in precision shooting… with its inherent natural ergonomics.” One claim we do believe, is that the thumb lever may help disabled shooters. Additionally the manufacturer notes that because the “trigger guard completely encases the trigger” there is less chance of snagging the trigger in brush or vegetation.
How the Lever Trigger Works
The operator’s thumb goes into a port in the top of the polymer grip (see grip photo above). This allows ambidextrous firing by right- or left-handed shooters. The thumb points forward, in line with the barrel. The lever itself is contained INSIDE the lower. Watch this video to see how it works:
Is the Thumb Lever a Game-Changer?
“Ironhorse’s revolutionary trigger system has the potential to be a game changer” states Eric Prince, Founder of Blackwater Worldwide. “Our in-house testing has shown a significant decrease in shot group size when compared to a traditional AR-15 trigger set. We think this technology … could replace traditional triggers altogether at some point.” The manufacturer states that the thumb-operated trigger “has been shown to greatly enhance the experience of a large portion of the shooting community and makes shooting possible for those who have limited mobility or severely injured fingers.”
About Iron Horse and Blackwater Worldwide Iron Horse Firearms, based in Salt Lake City, Utah, was founded by a former U.S. Marine Ryan McDonald. The Patent-Pending Thumb-Operated Receiver was first developed in August of 2016 and became a fully operational system in the fall of 2018. Moving forward, Iron Horse Firearms will be doing business as part of Blackwater Worldwide.
In 2019, Blackwater Worldwide re-entered the firearms and ammunition market in the United States. In its first year of operation, it has acquired or developed multiple firearms lines and a proprietary ammunition line. The company is headquartered in Concord, NC.
Due to the COVID-19 Pandemic, many of our readers are dusting off their AR-platform rifles. Because ARs have a somewhat unique (and dirty) semi-auto operating system, we think all AR owners should learn how their rifles operate — from the inside out. This Sunday GunDay feature provides an “inside look” at the AR, with X-Ray and Cutaway views created through advanced 3D computer modeling.
AR15 Functions Revealed with 3D Computer Animation
Ever wondered how the parts inside an AR15 work together? Just exactly how does the reciprocating bolt carrier feed rounds from the magazine? How do the elements in the trigger group work and reset after each shot? How does the gas system bleed gas from the barrel and operate the bolt carrier? These and other questions are answered in this eye-opening video from 45Snipers. Using “cutaway” 3D computer animation, this 5-minute video shows all features of an AR15 inside and out. This fascinating firearms animation allows the viewer to look inside the upper and lower receivers, into the bolt carrier, chamber, barrel, and magazine.
This video starts off slow and has annoying background music, but it is well worth watching if you own or shoot any AR-platform rifle. It illustrates all the key operations during the charging, loading, firing, and ejection processes. The cutaway animation shows how rounds are stripped from the magazine and then chambered. It then shows how every part of the trigger group works, and how the firing pin strikes the primer. You can even watch the bullet move down the barrel before the empty shell casing is removed from the chamber and tossed out the ejection port. Here are sample frames from the video:
How AR-Platform Rifles Work — General Introduction
To help reader understand the general operation of AR-type rifles, this video shows the control functions of an AR and how the upper and lower sections work together.
Cutaway 3D Animation of AR15/M16 Action — Watch Video
Here is an excellent “cutaway” animation by Thomas Schwenke that shows how an AR-15 functions — how the entire loading cycle works from start to finish.
AR platform rifles are semi-automatics version of the M16. These feature distinctive upper and lower receivers which can be readily separated via front and rear pins. The upper includes the barrel, handguard, forward gas tube, and bolt assembly, while the lower contains grip, trigger group, fire selector, and mag well. In addition the lower is attached to the stock which encloses the buffer assembly.
The original ArmaLite AR-15 was a select-fire, air-cooled, gas-operated, magazine-fed rifle designed by American gun manufacturer ArmaLite in 1956. It was based on Armalite’s AR-10 rifle chambered for the 7.62×51 NATO (.308 Win). In 1959, ArmaLite sold its rights to the AR-10 and AR-15 to Colt. Some key modifications were made — most notably, the charging handle was re-located from under the carrying handle to the rear of the receiver. The redesigned rifle was adopted by the U.S. military as the M16 carbine, which went into production in March 1964.
Here are the main tools you’ll need to assemble an AR-platform rifle
In these challenging times, many Americans are buying an AR-type rifle, or starting an AR project — assembling the rifle from available uppers, lowers, and parts kits.

Today, AR-platform rifles are hugely popular. Dozens of manufacturers sell AR-type rifles, in a wide variety of configurations and calibers. But before there were M16s and AR-15s, ArmaLite produced a 7.62×51 caliber rifle, the AR-10. Yes before there were millions of 5.56 black rifles, there was a .30-caliber big brother with reddish-brown furniture. Invented by Eugene (‘Gene’) Stoner for the Armalite company in the late 1950s, this is the father of all of today’s AR-platform rifles. Way ahead of its time, this remarkable, select-fire battle rifle weighed just 7.25 pounds as first developed.
If you’re curious about the AR-10, in this video, Jerry Miculek puts an original 1957-vintage AR-10 through its paces on the range. This extremely rare, early-production rifle was provided by Mr. Reed Knight and the Institute of Military Technology. (The gun in the video was actually produced in the Netherlands under license, see video at 4:40.) This AR-10 is the direct ancestor of the AR-15, M16, and many of the modern sporting rifles that we use today.
The AR-10 was slim and light, weighing around 7 pounds. Some folks might argue that the original “old-school” AR-10 is actually better than some of today’s heavy, gadget-laden ARs. The AR-10’s charging “lever” was under the carry handle — that made it easier to manipulate with the gun raised in a firing position.
You’ll notice there is no “forward assist”. Inventor Gene Stoner did not believe a separate “bolt-pusher” was necessary. The forward assist was added to solve problems encountered in Viet Nam. Some critics say the forward assist “only takes a small problem and makes it a big problem.” For today’s competition ARs (that are never dragged through the mud) the forward assist probably is superfluous. It is rarely if ever needed.
Note also that the handguards are fairly slim and tapered. Today, six decades after the first AR-10 prototypes, we are now seeing these kind of slim handguards (made from aluminum or lightweight composites) used on “full race” ARs campaigned in 3-gun competition.
History of the AR-10
The AR-10 is a 7.62 mm battle rifle developed by Eugene Stoner in the late 1950s at ArmaLite, then a division of the Fairchild Aircraft Corporation. When first introduced in 1956, the AR-10 used an innovative straight-line barrel/stock design with phenolic composite and forged alloy parts resulting in a small arm significantly easier to control in automatic fire and over one pound lighter than other infantry rifles of the day. Over its production life, the original AR-10 was built in relatively small numbers, with fewer than 9,900 rifles assembled.
In 1957, the basic AR-10 design was substantially modified by ArmaLite to accommodate the .223 Remington cartridge, and given the designation AR-15. ArmaLite licensed the AR-10 and AR-15 designs to Colt Firearms. The AR-15 eventually became the M16 rifle.
AR-10 3D Model Shows Internal Parts
If you want to see more close-up details of the AR-10, computer artist Stefan Engdahl has created a very detailed 3D model of the AR-10 for use in computer simulations. This computer model features 18 separate objects so you can look at details of frame, barrel, trigger, sights and more.
Here are some additional images of early AR-10 models, with various configurations. Multiple handguard and muzzle options were employed during early development.
Color AR-10 photos from Arms Izarra, a Spanish company specializing in de-militarized, collectible firearms. Interestingly, this particular AR-10 was produced in the Netherlands under license.
Looking to shoot an AR-platform rifle out past 500 yards? Then you should read two articles by AR guru Glen Zediker. Author of The New Competitive AR-15 and The Competitive AR15 Builders Guide, Zediker is an expert when it comes to AR-platform rifles. Glen believes ARs have excellent long-range capability, provided they are built to high standards, with good barrels.
Glen says: “a properly configured AR-15 is easily capable of good performance at 500+ yards. Good performance means it can hit a 1-foot-square target all the time. Competitive shooters can cut that standard in nearly half (the X-Ring on an MR1 600-yard NRA High Power Rifle target is 6 inches, and high X-counts are commonplace among more skilled shooters).”
Published in the Cheaper than Dirt Shooter’s Log, Zediker’s articles first cover the history of the AR-15, and then explain how AR-platform accuracy can be optimized. Part One reviews the AR’s development as an accurate firearm, tracing its evolution from a Vietnam-era combat weapon to what is now a favored target rifle of High Power competitors. READ PART ONE.
Part Two discusses the specifics that make an AR accurate at 500 yards and beyond. Zediker talks about barrel configuration (profile and twist rate), bullet selection, floating handguards, and proper mounting of optics or iron sights. READ PART TWO.
Barrel Twist Rate
To stabilize anything longer than a 68- or 69-grain bullet, the barrel twist rate must be — at minimum– 1-in-8. Twist rates reflect how far the bullet travels along the lands or rifling to make one complete revolution. So, 1-in-8 (or 1-8, 1:8) means “one turn in eight inches.” I think it’s better to go a little faster in twist. There is nothing wrong with a 1:7 twist. The 90-grain bullets require a 1:6.5, and that is getting on the quick side. If you want to shoot Sierra 77s or equivalent, and certainly anything longer, 1:8 is necessary. By the way, it is bullet length, not weight, which constitutes the necessary twist rate to launch a stable bullet.
Optics Mounting
Correct optical sight positioning can be a challenge. With a flattop upper, I need a good inch additional forward extension at the muzzle side of the upper for the sight mount bases to avoid holding my head “back” to get the optimal view through the scope. A longer rail piece is necessary for my builds as a result.
Buttstock Length and Adjustment
An adjustable buttstock is valuable, and even more valuable if it’s well-designed. Mostly, a standard stock is too short, and the cheek area sits too low. Adding length helps a lot by itself. There are assemblies that replace the standard buttplate to allow for length and, usually, height and rotation adjustments for the buttpad. An elevation-adjustable cheekpiece is a big help to attain a solid position.
