AR mag. adapter block, sten mags
I have a complete Olympic arms rifle and I have their complete conv. kit for 9mm, upper and mag adapter. This is probably one of their early models as the mag adapter is a long clumsy thing with a long release lever, the sten mags need a bolt put in the rear so the lever can retain them. This is a real poor setup as in rapid fire sometimes that lever rocks back and the mag falls out! Bummer! I see Brownells sells a mag adapter for the Oly system that uses unaltered sten mags and is supposed to be quite solid and stable, does anyone out there have any experience with this item and what does the retaining latch lock onto?

I have a 9mm upper for my AR. It uses sten mags with a block you install in the mag well prior loading the mags. It works very well. I dont know who made this unit as I got it from a friend. It works reliably and the mags dont work loose when firing. I'll try to get some pics posted.
OK, here ya go.

Hey Lefty, that looks like just what I got direct from Olympic only I don't see any screw heads sticking out the back of the mag., my unit requires a hex screw in rear of mag for that lever shown to latch on to. I think the spring in there is way too weak cause it will back off and release the mag in rapid fire. I have to use a heavy elastic band (like girls use on pony tails) thru the trigger guard and looped over the lever, that works but it's a pain. The unit I mentioned from Brownells seems to fit flush with the mag well and hooks on the back of the mag somewhere, maybe where yours does. Exactly where on the mag does your catch engage? 0 -
There are no screws in the magazines. The latch engages just below the extra layer of metal built onto the STEN mags that wraps around the back. 0
