Was playing with my gun the other day and noticed the bolt release button was loose. What?! This was the OEM release lever that I drilled and tapped for a bolt release pad. For some reason that process didn't go very well, probably the wrong tap. So bought a Redneck Tactical bolt release tab and pressed-on for several + years. You'll notice I polished the heck out of it as well. Polished it in places that didn't need to be polished! I also recently did a little bending adjustment for easier loading. Probably went something like this: Not enough, still not enough, oh too much, back the other way, a little more ahh just right.
So here is what I think happened:
Possibly weakened the bolt release button fitment during the drill and tap process.
Polished off too way too much material on the flange of the button where it's pressed into the lever.
Weakened everything by bending it back and forth a bit as noted in the video above.
Luckily I had a GG&G shell stop as a spare and swapped it out. Other than a little polishing, I don't think I'm gonna mess with it!
My stupidity is your gain!?
