The Precision Armament Hypertap 5.56 brake (brand part no. A04612) is the slim-body version of the company’s flagship muzzle brake, threaded 1/2×28 for .223 and 5.56mm rifles. Its hybrid baffle design and convergent-divergent port geometry give a rated recoil reduction of up to 84 percent while keeping safe 35-degree baffle angles. The brake installs with an integrated timing nut instead of shims, and two spanner wrenches come in the box. It is made for shooters who want a compact brake that is easy to tune and easy to swap with a suppressor.

Frequently Asked Questions

Which rifles will it fit? It is threaded 1/2×28 for .223 and 5.56mm rifles, such as AR-15 style rifles with that standard muzzle thread.

Can I use it on a barrel shorter than 14.5 inches? Precision Armament gives 14.5 inches as the minimum recommended barrel length. It says you can use it on a shorter barrel but does not recommend it, because gases and concussion are directed back toward the shooter.

Should I drill out the pilot holes? Precision Armament advises deciding first whether you need to, since the brake already reduces so much recoil that there may be little left to cause muzzle rise. Unnecessary drilling can overcompensate and reduce the recoil reduction rating.
