Does anyone own or know anyone who owns this kit for the sten mk. III. semi auto sten conversion It's supposed to convert the sten to a closed bolt semi-auto. I have a mk. III parts kit and am very interested in buying the conversion. |

I built a semi-auto using a previous version of that kit. There were a few problems that they may have fixed in the new version. The springs weren't very good, especially the hammer spring (it tended to last about 20 rds). The rear trunnion is flat, lacking the bevel found on a real sten. And the extractor tended to be pressed too far against the bolt face. I replaced the hammer spring with FAL recoil springs, beveled the trunnion to match the barrel, and reduced the extractor tension with some JB weld. Oh, and the spring attached to the sear tended to slip off. hinking.gif As I said, some of those issues may be resolved in the new kits. There was a yahoo group devoted to building semi stens, I'm not sure if it's still around. Once everything was tweaked, it runs reliably and is a fun range toy. I love the looks it gets. |

I've only shot it at 25 yds, and can't remember what size groups I got. Usually I just plink away at steel plates - I only put it on paper to zero the sights. It might have been about 3 inches? Don't expect precision. I welded on a barrel extension and added a piece of tubing to simulate a suppressor. Not the best pic: http://img228.imageshack.us/img228/8955/stencompleteiv5.th.jpg |
