The large port presents a broad surface for gasses to impact against, which keeps the muzzle down and the sights on target. Installs easily to any barrel threaded with 5/8"-24 threads.

I have this muzzle brake
I have this muzzle brake on a 300 blackout ar. The brake works very well. The range was very busy today with people sighting in their deer rifles and everyone i asked said they muzzle blast wasnt annoying, most didnt even notice i was shooting with a muzzle brake. The fit and finish are also very good. Very happy with this purchase.

Needed a comp for my 6.8m
Needed a comp for my 6.8mm AR. I really liked '74 comps, so this fit the bill. It works as it should. Reduces recoil at about half the price of other name-brand comps. Central Missouri Machine Gun makes great products. 4 bullets for the comp and +1 for the price.
