I'll keep this short as possible. Got my Dissipator sighted in the other day and hae 2 little problems.
1. Rear sight needed to be moved almost all the way over to the left. Never had one need this much adjustment before.
2. Was using PMC 55 gr BT FMJ match to sight in with. Kept failing to feed the next round in the mag and would not lock the bolt back on last shot. Then tried some Wolf that someone had given me. Same problems. Remington UMC worked fine. PMC and Wolf worked fine in other 3 ARs we were sighting in, 2 of wich were new also, as did the UMC. Mags worked fine in all other rifles as well.
Could my Dissipator have some problem with the gas ports, and could their be a problem with the barrell and sight alignment for the rear sight to need to be moved so far over?
