Ballistic Stats
The Atchisson AA-12 is a fully-automatic 12 gauge shotgun whose development began in 1972 with the goal of taming the considerable recoil you get from 12 gauge shells. This is achieved with a unique gas and recoil system that employs multiple springs to absorb and space out the recoil while preventing the bolt from ever hitting the back of the receiver through a concept called "constant recoil". Made entirely of stainless steel with two polymer shells making up the body of the

Aa-12 Capacity
The AA-12 is a 12 gauge shotgun with a 3” chamber and feeds from single-stack 8 round detachable box magazines as well as 20 and 32 round drum magazines. Being a full-auto-only gun with a fire rate of 300 rounds per minute, the AA-12 can be fired in single shots by a well-trained user with quick trigger pulls.
Aa-12 Feature
The AA-12 is a fully-automatic shotgun that fires from the open bolt and operates on a long-stroke gas piston. It is built with a 15 or 18 inch barrel depending on the model with the newest model lacking iron sights in favor of a short, raised optics mount. The AA-12 has a dual-spring recoil system with a weaker spring handling the bolt’s necessary travel while a heavier spring absorbs any leftover kinetic energy and prevents the bolt from hitting the back of the receiver.
Aa-12 Ergonomics
The AA-12 has a very tall receiver yet still feels very similar to a modern sporting rifle, just with simplified controls. The charging handle is located on the top of the gun between the sights, the magazine release sits under the trigger guard, and the safety is located between the user’s ears. The magazine is inserted by sliding it up a stainless steel track where it locks in place against the magazine latch.
Aa-12 Mobility
Measuring 37 inches long with an unloaded weight of 10.5 pounds (or 15.5 pounds with a 20-round drum magazine), the AA-12 scores relatively low for mobility. However, it’s an AA-12, so if you were issued one, the firepower it offers could easily overshadow its rather excessive weight.
Aa-12 Fit-N-Finish
The AA-12 has a two-piece composite shell making up the stock, grip and handguard. The receiver, bolt and all other internal components are made of a specific variant of stainless steel that self-lubricates with the carbon deposited onto it from firing the gun. The near 4-foot long recoil spring and the recoil buffer spring work together to provide a sort of constant-recoil operation that the AA-12 is known for.
