I have an upper that I don’t want to part with for various reasons. Today, the wear on the rear of the indention that holds the charging handle latch got bad enough that on the last round of every magazine, the latch would come loose and shoot back into my nose. not enough to be painful (yet) but pretty dang annoying.
When the charging handle is fully forward, I can pull it to the rear w/o touching the latch. the latch comes loose and slips right past the receiver with a very moderate amount of pull. (nowhere close to the normal force you’d use to pull the BCG back against the spring.)
if anyone has any idea how I could maybe rebuild that part of the receiver, or otherwise solve the problem without replacing the receiver, i’d love to hear it.
Sometimes if you find a steel latch (like on the PRI gas busters) that has a jagged edge is bes to dress is down with some wet/dry 1000 grit sandpaper so it won’t eat up the notch on the upper receiver.
you know, I didn’t even consider JB weld. That’s a really good idea. I was thinking epoxy or bondo or something, but I bet JB weld would work really well.
