I just got my tracker at the beginning of July and have been running it on my Cooper 6.5-284 and Ridgline 6.5 creedmoor. It's the first Suppressor I've ever been around so my $.02 aint worth much but Im impressed. Slight POI change but accuracy hasn't been affected. Shoots the same to 700 yards. Love hearing ringing steel without earmuffs on!
