DETAILS PLEASE!?

Atchisson A-10 12gauge automatic shotgun?

Quoted: Atchisson A-10 12gauge automatic shotgun?

That's what it looks like, but I've never seen a flat-top version, or even heard of an after-market company making stuff for them.

The only Atchisson I’m familiar with was his “Streetsweeper”  prototype of the late 1960’s. If that’s the A-10 your on the right track. Back around 1980 I met a fellow trying to sell a select fire 12ga. later called the “Atchisson Assault 12” the company's name at some point was “Scepter”. The deal was you paid $300 and if the gun made it to production you got one. I far as I no production guns were produced. This is the local representatives Shotgun News ad for the “Atchisson Assault 12”.

Then in 1982 after the failure of the “Atchisson Assault 12” our local rep decided to bring out his own shotgun base on the AR-10. He had been making semi-auto AR-10 lowers. Using a Teclo AR-10, a mock up was made,  an ad run in Shotgun News.

What I have pictured in my original post is the firing prototype.
