So my buddy who works at a gun shop / shooting range gives me call and tells me a customer brought in a pre ban DPMS that will not cycle, it will shoot but not cycle a second round. He removed the BCG from his gun and slapped it in the DPMS and it ran fine. So i go in last night to shoot and end up taking a look at the gun, tried shooting it and it won't cycle. The spent case does not get stuck and is in battery when i pull the handle back. So i remove the BCG and disassemble and am unable to to get gun scrubber to flow through the gas key and finally decide it is clogged. The guy who owns the goes home and get pipe cleaner and i hit the key with barrel blaster but for the life of cannot get anything through. I finally take a look with a flashlight into the gas key where in meets up with the gas tube and i see something lodge in the key. I recognized what was stuck in there and we decided to remove the gas key from the carrier and get a brass punch and bang out the obstruction.
