Some information or something is missing from this thread. It is obvious the gun in the photo was not new. I find it hard to believe EMF would sell something they knew was cobbled up by some amateur smith. The screw in the trigger guard in the photo is not the correct screw. The buggered up screw holding in the bolt spring and the spring itself were poor work. Oh, there is no torque spec for the spring screw. OP are we gettilng the whole story? You ordered this gun from EMF new and this is what you got from EMF? If so you should be sending it back.
Sorry I had the wrong screw: I will say it doesn't help that none of the 5 screws are exactly the same size. 3 have sloppy angle cuts. Plus it's my fault for not paying closer attention. Actually I did pay attention to the screw order. I started second guessing myself on the re-install when I noticed the 2 backstrap screws were differently sized length wise. I've since checked them under magnification and see that one has a angled cut on the end. So with the naked eye appeared shorter. Fortunately the thread pitch appears to be the same on all 5 screws. Even though none of them measure the same length using calipers.
I I have owned this gun for at least 2 years. Maybe a little longer. I just recently got around to get ready to shoot with it when I notice the problem. EMF says if there was an issue I should have reported it sooner. From their standpoint they can't say I didn't mess it up myself, and now am trying to get them to take care of my problem.
I fully understand that . After-all it is every bit of a 2 year old purchase. I'm just going to order all 5 New Screws . With shipping it doesn't come to $30.00. 2 of the screws are pretty buggered up. And I didn't do it. I have a nice brownell's set of heads with a wooden handle. There's over 30 bits . Finding the exact size is a no brainer. As you know this makes screw removal easy. None of mine were hard to remove.
It's pretty obvious someone has played around with this gun. Lesson learned on my end. Fortunately the fixes are cheap and easy.
I might even owe my life or at least my eyes and hands to blank rounds. If I'd been using live ammo I'd have been screwed.
Thanks for the help everyone : To Major a special thanks for details
