OK Guys, I have my new Rem. 700 SPS in 300rum. I Have been told to shoot it first be for changing the barrel to see how the accuracy is. I want to shoot a lot, so I think I need a muzzle brake. I have a led sled but don't wont to risk braking the cross hairs. Are all muzzle brakes the same? I have looked on the site for info. Not sure witch one to get. All suggestions welcome. Thanks Guys!
