This video goes over some tips on how to examine your bolt carrier group for your AR-15 to be sure it's going to function properly and things I learned from receiving a brand new bent firing pin
I haven’t noticed any issues like that but I built my first ar haven’t even fired it jus dry firing a little bit and I noticed the bottom of my bcg has a terrible wear mark on the front bottom part almost like it’s grinding against the hammer when it slides back, what does this mean?
good vid. quick question,is it common to have a bad/bent firing pin from a new BCG, mine its spikes NiB BCG and last week took it to the range, it did fire ones,second time it would like dent the primer,since i can do any dissasembly at the range i had to wait till i get back home. so i took out the BCG and notice the firing pin it wasnt align with the hole,it moves freely and it wont go in the hole till i took out the pin and put it back in it looked fine. so i dry fire with some dummie round, took out the BCG and firing pin was again misalign.
I'm a Quality Manager for a gun manufacturer which produces thousands of BCG's. You have a bad bolt. Sounds like there's runout in it from the manufacturing process.
