Shiny new Piercision 5-Port Self-Timing Muzzle Break .30 cal, 5/8-24 thread.
$130 shipped anywhere in the lower 48. $15 more for Alaska or Canada.
I also have an Eberlestock “Just One” rifle-carry backpack I'd let go of for $250 OBO. Let me know if interested and I'll pull it out of storage...
This is the self timing barrel tuner muzzle brake from without warning, the tmb.
How many people are playing with tuners like this on their precision rifles?
