Their, muzzle brakes,comps, stabilizations modules are not supposed to have angeled hole to act as a brake. That is probably why they call them a "stabilization module". They destabilize $$$ from your wallet to theirs and you never knew what happened. Im sure if it actually improves your groups its probably more to do so with weight than anything. I spoke to them a few times years ago. They had already discontinued their kudu rifle with helical fluting and came up with snake fluting. They said their testing indicated a snake fluted was "SLIGHTLY" more accurate than than both unfluted and straight fluted, when i asked for data, they changed the subject. Im sure they were paying a fee to ershaw or someone for the helical fluting. More $$$ means more accurate. If you wrap a 1" thick roll of hundred dollar bills around the muzzle you rifle it will be more accurate and you will get many more compliments, just dont walk away from it while im around ;). Ill call it the dead president bullet star gate.
