Although each EVOLUTION comes with 1 of each caliber brake (3 total), some may opt to purchase additional brakes for other weapons. All of our brakes are 4140 stainless and the production models from this point forward will have a black nitrite finish (rather than the bead blast as seen in this picture). Each will be laser engraved with the proper caliber. Standard threads for .223/5.56 attachment 1/2 X 28 and 5/8 X 24 for both .264/6.5 and .30 cal.
