[QUOTE="Reelamin, post: 2784471, member: 42157"] Need some help if possible. New build. My bolt wont lock back on last round, and will if I pull charging handle back on same empty magazine. I have only built with mid and carbine length AR gas tubes and carbine/pistol buffer tubes. I wanted to build a very accurate AR, and wanted a fixed full length stock. Aero barrel, Aero Adj Block, Aero rifle length tube, Mag Pul carbine tube/spring/buffer. My rifle length buffer tube will not fit the Mag Pul PRS Lite stock so had to go with carbine stock tube. I get good ejection 3-330 and at worst 5 with gas block fully open. Bolt will not lock back no matter what the gas block is set at. Take any info before I tear into it and start throwing changes into it. Easy to just put the rifle tube/spring/buffer on it, and if it works I need to find another stock that will fit it. I would prefer to just stick with the Carbine tube and my PRS Lite stock. Edit....it is a Superlative Arms Adj. Gas block, Aero on the one that is running like a top. Put the rifle buffer tube, spring, buffer on and same results. Swapped out the Superlative to a standard Aero block and same results again. [/QUOTE]
