Please help as I'm putting together my first AR... Bushy lower, Mod 1 Lower Parts Kit... And using the build instructions from this site...
I go through each of the holes with a drill bit that closest matches their size from my set that goe from 1/16 to 1/2 in 1/64 incriments. When I drop the bolt catch plunger in the recessed hole is seems sticky, so I re-ream the hole and inspect the plunger... I take a we bit of sand paper to a small bur on the plunger, drop the spring in, then the plunger, and while I'm checking it for freedom of movement, it stays all the way to the bottom of the recessed hole... I put Kroil on it and tapped the snot out of it with the plunger faceing down... hoping that it'll pop itself out, but no luck...
Any suggestions?
