Four Great Firearms Animations

Firearms 3D Animation Gun Videos Schematic

1. How an AR-15 Works

Ever wondered how the parts inside an AR-15 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. There’s a second AR-15 Video that shows all the internal and external parts of the AR-15 Rifle. CLICK HERE for AR Parts Animation.

2. How an AK-47 Works — With Parts Assembly

This animation shows how the AK-47 (officially Avtomat Kalasnikova model 1947) rifle functions. This very realistic video shows the component parts of the AK47 coming together. They you can see how the fire control system works to ignite the primer, sending the bullet down the barrel. Next you see how the gas piston pushes the bolt carrier rearward to chamber a new 7.62x39mm cartridge.

Tech Note: This high-quality 3D animation was created by Matt Rittman using Cinema 4D and After Effects software. Corona renderer was used in order to create realistic materials and reflections. Credit Forum member Captain Dave F. for finding this video.

3. How a Pistol Cartridge Fires

This cool 3D video from German ammo-maker GECO (part of the Swiss RUAG group of companies) unveils the inside of a pistol cartridge, showing jacket, lead core, case, powder and primer. Uusing advanced CGI rendering, the video shows an X-ray view of ammo being loaded in a handgun, feeding from a magazine. Then it really gets interesting. At 1:32 – 1:50 you’ll see the firing pin strike the primer cup, the primer’s hot jet streaming through the flash-hole, and the powder igniting. Finally you can see the bullet as it moves down the barrel and spins its way to a target. If you’ve ever wondered what happens inside a cartridge when you pull the trigger, this video shows all.

4. How a Rifle Cartridge Fires

This CGI video shows what happens inside a rifle chamber and barrel when a cartridge fires. The 3D computer animation reveals every stage in the process of a rifle round being fired. X-Ray-style animation illustrates the primer igniting, the propellant burning, and the bullet moving through the barrel. The video then shows how the bullet spins as it flies along its trajectory. Finally, this animation shows the bullet impacting ballistic gelatin. Watch the bullet mushroom and deform as it creates a “wound channel” in the gelatin.

Possible Progress on ITAR Regulation of Gunsmiths

ITAR Department of State Rule Change

If you are a gunsmith, or do any machine works on firearms, you need to know about ITAR, the International Traffic in Arms Regulations which are enforced through the U.S. Department of State (DOS). ITAR applies to companies that create sophisticated weapons systems. However, under DOS interpretations in recent years, ITAR may also apply to persons and businesses that do simple, basic gunsmithing tasks. That could require filling out lots of paperwork, and paying the Fed’s hefty fees, starting at $2250 per year. A Guidance Statement issued by the DOS Directorate of Defense Trade Counsels (DDTC) in July, 2016 (under the Obama Administration) gave rise to serious concerns that DOS was going to require every gunsmith to register under ITAR, under threat of massive fines and penalties. READ About DDTC ITAR Guidance.

Thankfully, it appears that the Trump Administration is working to narrow the scope of ITAR so that it would NOT apply to basic gunsmithing activities, and not apply to common gun accessories that are not exported. IMPORTANT: Changes have NOT been made yet, but it appears the Feds are heading in the right direction, with the DOS willing to modify its definition of “manufacturing” so ITAR would not embrace basic gunsmithing tasks such as threading a muzzle.

The Gun Collective reports that: “The Directorate of Defense Trade Counsels (DDTC) is working on revising the ITAR regulations which will help the gun industry[.] Gunsmiths having to pay hefty fees, register and comply with ITAR may no longer be a problem if this goes through as planned. Fortunately, we don’t have to wait for Congress to take action, but rather an agency, which appears to be taking initiative to get it done. As always, time will tell, so be sure to keep your eye on the Federal Register….”

While nothing has happened yet, it appears that this administration is working to revise ITAR. For members of the firearms industry, this is a big deal and will be beneficial to all. There is no reason that a gunsmith should be required to register and comply with ITAR to simply thread a muzzle. It will also allow companies to more easily export their products around the world. (Source: The Gun Collective)

The Gun Collective further noted that: “The topic that will be of the most interest to us would be the definition of manufacturing[.] You may remember DDTC’s July 2016 letter, which issued “Guidance” as to who would have to register under ITAR [and suggested] that now gunsmiths would have to register as well. The definition of manufacturing is an important one to define and one that had broad ranging implications as the industries covered under ITAR are wide ranging, everything from the firearms industry to airplanes and missiles. The Guidance stated that ITAR registration was required for gunsmiths who machined or cut firearms, such as the threading of muzzles or muzzle brake installation which required machining. At a hefty $2,250 a year to register, ignoring all of the other things that go along with ITAR, it is easy to see why this would be problematic for most small businesses.”

Here is the key language in the DDTC’s “ITAR Registration Requirements – Consolidated Guidance” Ruling of 7/22/2016:

2. Registration Required – Manufacturing: In response to questions from persons engaged in the business of gunsmithing, DDTC has found in specific cases that ITAR registration is required because the following activities meet the ordinary, contemporary, common meaning of “manufacturing” and, therefore, constitute “manufacturing” for ITAR purposes:

a) Use of any special tooling or equipment upgrading in order to improve the capability of assembled or repaired firearms;

b) Modifications to a firearm that change round capacity;

c) The production of firearm parts (including, but not limited to, barrels, stocks, cylinders, breech mechanisms, triggers, silencers, or suppressors);

d) The systemized production of ammunition, including the automated loading or reloading of ammunition;

e) The machining or cutting of firearms, e.g., threading of muzzles or muzzle brake installation requiring machining, that results in an enhanced capability;

f) Rechambering firearms through machining, cutting, or drilling;

g) Chambering, cutting, or threading barrel blanks; and

h) Blueprinting firearms by machining the barrel.

Having a Merry Christmas with a .50 BMG Barrett M82

Barrett 50 Caliber .50 Ca Xmas Christmas shooting video

This 50 Cal Days of Christmas video features some fantastic slow-motion footage of a Barrett .50 Caliber M82. This bad boy pumps out some serious muzzle flash. Watch carefully at the 1:05 mark and you can see the .50-caliber projectile exit the muzzle brake and spin through the ball of smoke and flame. For best viewing, you may want to change your video settings to 720p or 1080p High Definition and view full-screen (using the video controls).

The video carries “overkill” to the max, as the shooter uses his big Barrett to blast Christmas ornaments and a snow-globe. To top things off, at the 2:50 mark, the shooter fires the .50 cal at a pyro-equipped gingerbread house. (The gingerbread shot is taken from a standing hold no less!) The results (at 3:22) are impressive — gingerbread house becomes flaming gingerbread pudding.
