Eyebrow Remover!


Works great as a comp, just be ready to draw on new eyebrows after, giant concussion to your face and any neighbors.



This bad boy is a fantastic brake, makes felt recoil almost zero and enables very rapid follow up shots (my red dot barely even moves now). Limited application, best for competition probably. It’s louder than thunder and if you take this to a class or shoot indoors people are going to hate you. It can provide a pretty decent fireball as well, check out some YouTube reviews. Best comp out there in regards to most effect on performance. Oh, and it is SOLID; quality machined.



This Precision muzzle brake is probably one of
the top muzzle brakes you can purchase. I bought
mine a couple of years ago and it performed as
advertised. I paid a little more for mine. It is a good
deal through Primary Arms!

If you run rapid fire this is for you


It's incredible. The review done by Jeremy S. DOES IT NO JUSTICE. And he sings its praises after comparing it to dozens of other brakes.

Concussion to others, probably awful. I still have my eyebrows. But the muzzle stays where it's supposed to seemingly regardless of rate of fire.

Which is all I want this to do.

Highly recommended


I have one of these on my SDMR w/20" 223Wylde S/S Match bbl. A friend is severely recoil-averse (took me 20 minutes to convince him to give it a try). Firing 5.56x45 77gr OTM he was pleasantly surprised that the recoil was about the same as his CZ-457 .22LR target rifle.



This compensator works excellent! You will notice a big difference in the kick of your AR. It does make it a quite a bit louder when using in an indoor range, and you will get some muzzle blast that bounces off the walls back to you, but well worth it!

Great Break, Big Blowback

Really great comp, disappointed that shims weren't included, otherwise it would be a strong 5 star.
