Re: anyone know of good muzzle breaks for factory barr
Here is a short synopsis of what the military has discovered with brakes.
The more angled the ports are to the rear, the more efficient the brake but the greater the overpressure. This is why tanks and arty don't have angled ports, to save the crew's brains.
Increasing the number of baffles (in a non-pepperpot brake) follows the law of diminishing returns. Any more than 2 is a waste with 3 being really the upper limit
Pepperpot style brakes are generally less efficient but also produce less overpressure, and their efficiency is usually good enough. There's some rules for making the best pepperpot brake but I can't think of them off the top of my head.
Something like the Badger FTE brake is a good example of a solid brake design for all around use while the Barrett .50 brakes with the angled ports are the best for reducing recoil.
