Years ago I had my bolt action 458 Win Mag, Mag na Ported, did help some with recoil, seemed more noisy tho, things have come a long way since then. The first video shows a M14 on full auto with I believe a Smith Enterprises, USCG muzzle break and how controllable it is dumping a full twenty round mag of 308. Smith Enterprises makes some of the best M14'S built today.

The second video, both videos are from You Tube, is from JP Rifles website with their muzzle break featured, shown a full 30 round mag dumped holding the M16 rifle with one hand! JP Rifles makes some of the best AR15 rifles made today, my brother has one!
While muzzle breaks make full auto and semi auto and even bolt action rifles more controllable the downside is more muzzle flash and noise.
