So i finally had my Grendel out to shoot for the first time and put about 40 rounds through it.
It will not cycle fully.
It will extract the spent round but will not load a fresh round for some reason.
Now im no AR expert at all. Bought my first AR last fall and then built this Grendel and never fired it till today.
From what i can figure out it is under gassed or over buffered.
20in McGowen barrel with rifle length gas system.
Adjustable gas block the is tight, aligned. Tried 1/2 turn at a time from closed to full open.
Brownells BCG.
Magpull fixed rifle length stock and tube(A2)
Rifle buffer and spring.
ELander 17? round mags
Shooting Hornaday 123gr ELD
Any suggestions on what to look for?
Thanks
