You seldom see an AR without a muzzle device of some sort. Most of them come out of the box with a flash hider. Now, that's something we take off and drop in our extra junk drawer. You need something that will help you shoot better at the range or in the field. I'm talking about an AR muzzle brake.

Give Me 10 Minutes

Anyone who doesn't believe an AR muzzle brake makes a difference has never shot through a good one. All muzzle devices are not the same. First, you have to get it on and timed. The F1 Firearms flat-faced AR muzzle brake features flats on its top, bottom, and sides. Getting it timed is a matter of using a straight reference and some crush washers. Next, the design of the device must divert gas laterally to achieve any degree of recoil reduction. The trade-off is it's loud. Like with all muzzle brakes, you have to cover your ears. However, after running a box of ammo, you'll never shoot without a brake again.

Split The Difference

In today's world, most of us try to get the most out of anything. You don't have to settle for just a muzzle brake. F1 Firearms combines the traits of a muzzle brake with a 5.56 compensator. So, if you want to have the maximum reduction in felt recoil along with less muzzle rise, you have to compromise. Luckily for you, the F1 Firearms flat-faced 5.56 compensator gives you both. You should save yourself some time, aggravation, and money and kill two birds with one stone. When I say one stone, I mean an F1 Firearms 5.56 compensator.
