The sling swivel uses the same screws and 1 1/4" swivel found on the M1A1 TSMG. Look for the screws under the appropriate model listings. They also have beautiful new blued butt plate screws. These are made of some kind of black plastic that's easily shaped and fitted. Gunparts has repro 520 & 620 butt plates. The East Taylor bayonet mount repros may take this into consideration but don't know for sure. The barrel tapers are different between civilian and military M12s, which had a straight taper.

Counterfeit Trench Guns, LLC, converted these in addition to their Stevens offerings, but they cost about three times as much at the time. Both kinda pale in comparison to the light, slick handling Winchester M12. It's faster handling and the safety doesn't bite your hand. Personally, I prefer the Stevens 620 trench gun to the 520. There's no doubt that web M1 slings found their way onto these guns too, so take your pick. The rest were sold off as surplus, given to police forces, or provided to other nations as military aid. Only Stevens 620, Ithaca Model 37, and Winchester M12 trench guns remained in US inventory and service after WWII. The correct slings for WWII Stevens 520 and 620 trench guns are the M1907, M1917, and M1923 slings. BTW does your 520 have the 3 notches cut into the bbl?

Im currently working on a project for my son and daughter in law to earn some brownie points but next week I want to get this build started. I hunted around and found a complete mag tube and handle/operating rod so my plan is to leave the original front half of the gun intact and build a second trenchgun front half with my bits and pieces. Hopefully it will tighten up like my M12 unit did. It looks to be better than my first experience with an ET product. I left it on when I shot my plate rail the other day and it slid forward a couple of inches. It is a friction fit and will stay on the cut down bbl by itself. My heat shield is supposed to be an East Taylor unit made especially for the Stevens bbl dimension. David, that is exactly the measurement I need.
