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.
