Heartbraker 5/8-24 .875″ O.D.

These brakes can be used with a crush washer or a gunsmith can properly time and blend them to your barrel diameter with a minimum of 0.675″.  The outside diameter is 0.875″ x 3.000″ and internally threaded 5/8″-24 TPI which opens into the first port as shown in the picture. These brakes have 3 vertical ports to help control muzzle rise and 4 large ports on the sides. There is NO porting on the bottom to help reduce dust blast. They match up very well with our AR10-24 .308 & .260 barrels, and our AR-24 barrels available in .223, 6.5 Grendel, and .204 Ruger. Furnished with a stainless steel crush washer made by us. The dimensions on the crush washer are 0.875″ x 0.140″ with a bore of 0.630″. We have done some high-speed video work of these brakes in action. These clips really show the effectiveness of the brakes at 10,000 frames per second.
