This particular version of the Muzzle Brake has drilled holes vs. the standard slots. Please view the picture for a better view.
These brakes were one version we were considering and have decided against. In the meantime, our loss is your gain. These are closeout items and are limited in quantity.
A-2 Birdcage Muzzle Brake, fully machined with black oxide finish, specially designed for the JR Carbine. (Will fit other barrels with identical thread patterns.) Made ENTIRELY in the USA in Rochester, New York.
Warning: These muzzle brakes are designed specifically for your JR Carbine. Other muzzle brakes with identical threading may fit your JR Carbine, but many of them are designed for use with smaller caliber firearms (such as the .223 or .308). Unless their apertures are large enough to permit the bullet to pass through them, using them on your JR Carbine may result in death, serious injury and/or property damage.
