Matech sight lock detent problems
I have a Matech rear BUIS that I got a while ago. I really like the design, the profile of the sight stalk, and the adjustments.
What I don't like is the tiny bump that is supposed to hold the sight in the closed position until you need it. It's just a little metal nub, that's it. It doesn't work at all. Even dropping the bolt will cause it to pop open.
Is there a fix for this? Has anyone come up with a good solution?
