I have several great brakes for my 6.5 s Heathen, zrodelta gen 2, lil bastard.
My new rifle came with a Christensen Arms Slayer brake (the rifle is Also a Christensen arms) that muzzle brake is the best I have used and doesn’t blast your face off like the lil bastard. Although the Slayers baffles look exactly like the lil bastard. I don’t seem to get the back blast. They are almost indentical. Besides having screws to add to ports.
But for recoil reduction the slayer is seriously incredle. The rifle barely moves. I have mine with 2 top ports open.
The gen 2 ZRO DELTA is also good and has zero back blast. That is the new Alamo four star brand.
Knowing what I know now I will probably just get the Slayers for all new rifles. They also come in titanium.
Just thought I’d share my experience with what brakes I own and use(d).
