Having some trouble with cycling issues on my 18" Faxon group buy barrel. I'm running a POF Dictator adjustable gas block (open all the way) and it won't cycle 130 grain federal (will eject but not pick up the next round), however it will cycle 123 grain Hornady American Gunner ammo. I am using E-lander mags and the 4 round meg has trouble loading the first round and won't stay open after the last round about 75%. The 17 round magazine will stay open after the last round of 123 grain Hornady AG but again not with the 130 grain Federal. Brass is ejecting to about the 5 o'clock position and I can see where it is impacting on the brass deflector. Running a standard carbine buffer spring and weight. Since i'm close to POF I dropped the rifle off with them and they seem to be leaning towards the gas port size being too small. If POF determines nothing is wrong with their gas block then I'll throw a non-adjustable block on just to test and see if its a size issue, but I have no issues with the POF Dictator on a 5.56 20" rifle length system.
