Military Police System has come out with a unique select-fire 12-gauge combat/tactical shotgun called the “Auto Assault 12 Automatic Shotgun”, or “AA12 Automatic Shotgun”. The full-auto-only Auto Assault 12 Automatic Shotgun fires at a relatively slow rate of 300 rpm (rounds-per-minute) and employs the “Constant-Recoil” principle, which is a recoil attenuation/mitigation system that was first invented and patented for utilization in a gas-operated weapon by legendary small arms designer/developer L. James Sullivan for the Ultimax 100 LMG (Light Machine Gun), back in the late 1970’s. “Constant-Recoil” allows a lightweight gun to outhit a heavier gun on full-auto. Since it utilizes “Constant-Recoil”, the bolt group of the AA12 Automatic Shotgun never impacts the rear of the receiver, but rather runs out on the long 2-stage recoil/operating spring. This action eliminates the majority of felt-recoil, and thus greatly enhances controllability on full-auto. The result is more hits on target. The Auto Assault 12 (AA-12) Automatic Shotgun is manufactured from “corrosion resistant, high impact, heat-treated stainless steels and high-impact plastics”. Supposedly, the Auto Assault 12 shotgun requires no lubrication (unconfirmed/unverified). Rounds are fed from an 8-round box magazine, 20-round drum mag, or 32-round drum mag. That’s a lot of 12-gauge firepower in a fully controllable package. Since the AA-12 shotgun fires at the relatively slow rate of 300 rpm, there’s no need for a semi-auto setting on the AA-12’s selector switch. Any skilled operator can easily control the round output via trigger control, including singe shots and double taps. In other words, the operator’s trigger finger IS the selector switch. The Auto Assault 12 (AA12) Automatic Shotgun also features a quick-change barrel system. Barrel lengths are from 13″ to 18″. –

  1. @toiletcakes Hell yeah! Those games ruin these weapons. Can only shoot something 10 feet in front of you. Hell, I still use it tho. I love this gun, but game programmers fuck everything up; especially with it's range.

  2. @creamyapanties but do you rly think a spy could bring an aa12 unnoticed? no, they will use a mac 10. you think the assault troopers withh use a shotgun for long range shots? no, they will use an M16/M4. You think a sniper will snipe with this? you think soldiers will move quicky with this? no, its too damn heavy. this gun is a Close-Quarters-Combat gun and nothing more.

  3. @creamyapanties first off i dont play COD or MW3, and straight up fool, shotguns will NOT shoot as far as an m16, and its not as accurate as the M99, and not lighter than G36, and defenitely not as fast shooting as an Uzi. its a CQB GUN.

  4. bro….

    SPAS 12

    there. happy?
    BTW i know marine, navy, and coast guard ranks by heart, as well as uniforms. don't be pulling military stuff on me.

  5. A friend of mine that was a Colonel in the Vietnam war said his weapon of choice was the shotgun. At some point in the war he said the military went around gathering them up because of the mess it made out the people shot with it, but being a Colonel he was able to keep and use his throughout the war.
