AR15 won't cycle (Update)

[Jburke]

Just wanted to give an update. I took the gun back to the shop and they tested it and found out that the BCG was not lining up in the feed ramp properly so they filed it down a bit and did some test shots and the gun performed well. Thanks to everyone for all of your help and advice.

 

Makes you wonder about the machining process, eh?

Makes me wonder more about the shop it was bought from/brought back to.

I'm sure they just filed down a locking lug or two. No biggy..

Are the lugs hardened? If so,... most hardening processes are to the surface of the metal. Filing off the surface material can greatly affect the hardening value.
