Re: muzzle brake
Personally, I like the Surefire 7.62SSAL/RE. MY friend has one on his 700p .300 win mag and it has less than half the recoil of my 700pss .308. Also has one on his DD AR15. His has literally no recoil. I know some will say why buy the Surefire if your not utilizing their suppressors, but I really like the look of it as well. I also like the Badger FTE brake. I like the tactical look myself.
But, I will say that you won't have many fans if shooting around others. Shooting next to his rifle, there is a huge concussion when he fires.
Guess it all depends on what your preference and usage of the rifle will be. I believe than some competitions ban the useage of muzzle brakes. I am no expert, just offering my opinion.
