After 6 years of multigun my 18" Noveske Rogue Hunter upper is shot out. I decided to build an upper with a CMT billet upper, Ballistic Advantage 18" fluted barrel, Seekins adjustable gas block, and low mass RCA BCG, This is mated to the existing Noveske lower (which was very reliable with the 18" intermediate gas barrel) and has a Magpul UBR stock (carbine length), standard carbine buffer spring and Spikes ST-T2 buffer. During assembly I realized the old 18" Noveske barrel was an intermediate gas system, NOT rifle length. The new Ballistic Advantage barrel is a rifle length system and it is short stroking. I opened up the Seekins gas block all the way, swapped in an H buffer and eventually went down to a 3oz buffer. With relatively hot 77gr loads the rifle cycles, but with normal 55gr ammo it short strokes to the point where it rarely grabs the next round. I'd prefer to keep the UBR stock if possible. I read that the JP captured spring buffer system may be a solution, but before I invest that cash I am curious if there's a better solution. Although it is a dedicated competition gun reliability still matters. It seems opening up the gas port may be the other solution, besides converting a rifle length buffer tube. Is there anything else I should consider?
