My Grendel was shooting good handloads in the 1.5-2 MOA range. Which is kind of Meh. Taking off the A2 Flashhider, and putting on a Gamma .300 BO muzzle break; and replacing the crush-washer with shims, appears to have improved my accuracy, bringing it down to the 1-1.5 MOA range.
Also, the .300 BO Gamma muzzle break works great, and notably reduced felt-recoil. I suspect this is what contributed to the improved accuracy, as the gun just jumps less now.
FWIW, I went with the .300 BO muzzle break vs the 6.5 break, because it's about 1/2" shorter, and still fits the threads used on Grendels.
