[QUOTE="LanceS4803, post: 5165563, member: 9491"] Hopefully we have some knowledgeable AR smiths here. Have built multiple ARs, from SBRs to AR-10s, absolutely no issues. Until now. I stick with Aero, and have used this receiver, bolt carrier and buffer/spring combo before. So, known parts. This rifle has a 16" Hanson profile barrel, mid-length gas system. Will fire, reset trigger, but bolt doesn't go back far enough to pick up the next round and fails the bolt hold open test. Using same buffer and springs as other builds with same length barrel/gas system. Bolt moves freely, gas key is tight with good engagement of tube, all rings in place with great seal. Pulled the low profile gas block (screws and roll pin), holes lined up very well. (I set all my gas blocks with an SLR jig.) Checked barrel, no obstructions or burrs in port hole. I don't have the exact pin or bit, but hole is slightly larger than .070. Air flows through block and tube. The only thing I didn't do yet was swap lowers to try and isolate an upper issue from a lower issue. Too hot, sweaty and just forgot. Anyway, I've reached the end of TI'ing this thing and open to ideas. [ATTACH type="full"]93507[/ATTACH] [/QUOTE]
