So I have this AR in the safe for three years, never getting around to shooting it. got it out last week to do some shooting. load gun, pull trigger and it goes "click" not "BANG". having never fired this gun, and knowing nothing about the AR platform or how it works, I just waited a minute then ejected the still live round and tried again. and again. and again. I'm getting weak primer strikes but cannot tell why. custom gun made by a friend of mine. direct impingement, not gas piston. Rock River lower, Colt (Vietnam Era) upper. I don't know anything specific about the barrel or trigger parts
I watched a couple of vids and tore down the rifle for a thorough cleaning. it wasn't real dirty, but I figure cleaning can only help. not to mention I now understand how the BCG works and how the bolt is assembled. hosed out the trigger group with gun scrubber, lubed it all up and tried to fire again with same result.
best as I can tell the bolt is traveling as it should. buffer spring in good working order. the hammer is cocking properly, the firing pin is moving freely and the trigger is very smooth. I'm sure the person who built this rifle worked on the trigger as he is an accomplished gunsmith. furthermore, when a round is picked up and sent to chamber, the bolt travels forward with enough force to make a small mark on the primer, which is normal as I understand it. when I pull trigger, the firing pin is striking the primer, but apparently with not enough force to cause ignition. so, do I have a weak hammer spring, a bad firing pin, or something else?
