I do not remember if cycled without a spring and a buffer. I already ordered the Armalite kit and will touch up the points of contact on the ears with black paint I will keep keep you posted what are the results Thank You for the reply

What do You think my problem is?

It is 6.9685 inches or 6 31/32 in fraction

Good morning, Group. I am new here and into putting together rifles. Built successfully several AR15s,, but I hit the rock with this .308 rifle. It supposed to be a beautiful high end built and it is expensive, but it comes with a problem. I used a carbine AR15 buffer kit I had already in my parts boxes and it doesn't function right. The rifle was never shot. When charging the BCG gets stuck in the tube. When I pull half way, just enough to load it comes back the way it supposed to do. Lower is CMMG MK-3 with CMMG internals. Only the trigger is a Geissele (which I have no idea how to adjust, but this is for later) Upper came assembled by Falkor Defense with their receiver and handguard. Barrel is Proof carbon wrapped, rifle length .875 BCG is DLC made by Sharps Rifle Co. out of WY Attached are picture for reference Please, Guys, HELP If You think it is the buffer kit, please tell me what to get. Anything good I can find in stock.
