Instead of buying the tools needed to do the job, I decided to pay a gunsmith to install a Matrix Arms FF hand guard and a cheap lo-profile gas block. The GS also runs a pawn shop so I spent the repair time browsing his store. After awhile I walked back to his bench and he was hammering the handguard on with a rubber mallet. He said the gas block was very tight against the handguard. He finished up. I paid and left.
A few days later I was in the yard shooting a few of my guns. Grabbed the AR, chambered a round and it didn’t fire. As I inspected the rifle I noticed the BCG not going all the way forward. Cycling the bolt by hand, I can bump it forward and make it cycle. But it won’t cycle or extract any other way.
I took everything apart and scrubbed the hell out of it, lubed and replaced. Same problem. Thinking maybe the GS bent the gas tube, I ordered another tube and a better gas block. I’ll have to wait on those parts to arrive before going any farther. Do you guys think this will be the solution or could it be something else?
Thanks for reading and I appreciate any help.
