AA12 Sledgehammer Shotgun Available for Civilian Sale

As far as drool-worthy unobtainium goes, the mythical full-auto AA12 “Sledgehammer” shotgun ranks up there amongst the best of them.

We played with an AA12 at TriggrCon 2018.

AA12-Rollmark-1

Initially developed in the early 70s by Max Atchisson, the AA12 was designed as a full-auto-only open bolt 12-gauge shotgun.

Background of the AA-12 Shotgun

Continually tweaked for decades and pushed mostly in vain to military and law enforcement markets, the AA-12 was much more successful in scoring appearances in movies, TV shows, and video games.

With its stainless steel construction, gas-operated action, hefty recoil spring arrangement, and slow, roughly 360-rpm cyclic rate, the AA-12 was notable for minimal felt recoil and controllability in full-auto.

Atchisson sold the design in 1987 to Military Police Systems, which was responsible for all the subsequent product development. However, MPS saw limited commercial success and never fielded a semi-auto civilian variant of the AA12.

AA12-Muzzle-1

Fast forward to the present day, and Tactical Superiority and its new venture, Sol Invictus Arms, worked out a deal to finally make the AA12 available commercially.

Working closely with one of MPS's principals, they created a semi-automatic version, further refined the design, and set up modern production processes.

AA-12 Features

The civilian version sports a longer, NFA-friendly 18.5-inch barrel and fires from a closed bolt. The overall length is 38 inches and total weight is 10.5 pounds.

You can choose from versions with the iconic, original A-frame iron sights or the Picatinny rail on a riser that replaced them. 20-round drum and 8-round box magazines will be available.

Sol Invictus Arms plans for these guns to be limited editions of only 1,000 and is taking pre-orders on Armslist at $3,250.

    If all you people asking about the price would have read the entire article you might have noticed that the retail price was $3,250.00 and also that production was limited to 1000 units.

    Also, this article is from August 2018, or just over 2 1/2 years ago. So, I’m kind of thinking that that these are all sold out by now.

    Just saying.

      ….and you would be dead WRONG. Not a single AA-12 has been delivered. It is a proverbial shit show combining lawyers and the US Government (never a good combo).

  19. Gerardo Peaney says:

    As of 12/21 these guns are NOT being made by Sol Invictus Arms because there are court proceedings with the original owners of the shotgun. The ATF is involve and until these issues are resolved the gun are NOT being made!

  20. Tom Smith says:

    Fast Forward to April 2022….Sol Invictus, LLC has not responded to my FFL request for estimating a waiting time.

    After the ‘mostly peaceful’ protests – Chicom riots – of 2020 protesting America voting in Trump, understandably there’s a huge demand for the most brazen of firearms for civilian protection since law enforcement and the Supreme Court have been castrated by Chicom domestic terror reigns allowed to infest and flourish in their spy nests throughout liberal cities and universities across America.

    Our current illegally elected doofus president is just a puppet of the Chicoms so don’t expect any anytime soon.

  21. Tom Smith says:

    Your best bet is to find one of a thousand or so supposedly already in circulation…supposedly.
    If anyone has heard of anything different, please share your finding.
