I’ve had Krieger SPR, Noveske SPR and a Noveske SS “light weight” barrels and they all shot just under MOA For 10 shots but proved to be heavier than I wanted. Just changed the dynamics of the gun.
Right now I have a LaRue PredatAR barrel that is plenty light and just over MOA for 10 shots. I have a fixed 10x scope in an ADM mount that I can throw on there for groups or load work but the difference in handling is much better with the EOTech on there instead.
But my Colt and Sionics pencil barrels do everything I can ask of the 5.56 with LPVO’s and red dots, they see more use than any match gun I’ve ever had. Well I do have a 6.5 CM in a bolt gun and a 1000 yard plate that has my current attention...
