"The Grater GenII" Muzzle Brake

 Trojan Firearms sent me one of their “Gen II, The Grater” muzzle brakes when they sent the straight trigger that was reviewed earlier. Trojan is probably more noticeable for their pistol caliber carbines and California compliant rifles. This muzzle brake is the same one that they install on their “1776” rifle. This muzzle brake was supplied for review.

 The Grater is a nice looking muzzle brake. It has a Black Nitride finish, so it should hold up for a long time. Trojan manufactures the brake out of 4140 steel and it is threaded ½-28. It has 3 chambers to help mitigate the recoil impulse, in which it does a wonderful job. It also comes with an aluminum anodized jam nut, so you can index the brake wherever you like without having to use a crush washer. The jam nut concept is not new, but it does work, and since it is aluminum, you won’t have to worry about messing the threads up.

 More important, is the fact that it has 10 tuneable ports. 2 on top, 2 on each side at 90°, and 2 on each side at 45°. These ports are threaded 6-32 and have set screws that can be installed or taken out. The screws bottom out so that you can’t screw them into the bullets path. With these screws, one cane tune the brake for particular ammo or if they primarily shoot right or left handed. It does take some patience to get it dialed in, but the results are worth it. Say your recoil impulse moves the gun up and right. Just remove one of the 45° screws, on the side of the movement, and shoot it again. If it moves a bit left, start by removing one of the left side 90° screws. Hopefully you get the picture.

 As I mentioned earlier, The Grater does a wonderful job mitigating recoil. Even before “tuning” it to my ammo, I could tell a difference over the previous brake that I had on the rifle. I set up some targets at around 25yds to do some double taps on. At first the rifle moved a little bit up and right. After a little time spent messing with the screws, I think I pulled out a 45° and a 90° screw, it now shoots super flat. Double taps can be done as fast as I can pull the trigger and the sight picture barely moves. As with all true muzzle brakes, it does have the flaw of being extremely loud.

 I think Trojan Firearms did an overall good job when making the Grater GenII. It does what a muzzle brake should, and has the added benefit of being “tuneable.” Yes it is not some fancy titanium, or have some space age looks, but it also won’t break the bank at $79.99. Go take a look at Trojan Firearms, they make an effective brake, if not other stuff one might like.
