[QUOTE="Sanford, post: 2794176, member: 27733"] What barrel and gas tube length? "Not cycle" can mean several things - does it extract and eject the fired round but not feed the next round, something else? If it's ejecting okay where does the spent brass land? If it's not feeding the next round you might try a lighter weight buffer or a different magazine or different type of magazine with a different spring rate. Also guessing that you've already checked that your gas block is properly lined up with the port; opening up the port would be my last resort unless it's one of the barrels known for having small ports to begin with (have to search around the net, don't remember which they were but there was some discussion of them a while back).
