Did you ever figure this out? Did Fostech ever get back you you? If you still haven’t figured it out post the video you sent them or maybe a pic of the setup could help us determine what the issue is.

Any update on this? If you have found the fix it might come in handy to have it posted on the forum in case someone else has a similar issue down the road.

I think I had to remove the front and rear pin and work mine to get it together.. I haven't pulled it apart in ages. guess I need to do some cleaning.

Thanks for the update, too bad you had to send it back and it wasn’t just a simple fix. Keep us posted with how Fostech resolves this for you.

I found out that the buffer tube was in one turn too many. After it was backed off, guess what, closed like it should. In fact i can slap any upper to it now. I took it to casa grande and worked like it should with both the 9mm and 5.56 uppers.
