The Precision Armament Hypertap 7.62 1/2×28 brake (brand part no. A04614) is the slim-body Hypertap sized for .308 and 7.62mm bullets on a 1/2×28 thread, a combination found on lighter .308 builds. Its convergent-divergent ports are rated for up to 84 percent recoil reduction, with 35-degree baffle angles that keep gases off the shooter. An integrated timing nut replaces shims, and two spanner wrenches are included. Precision Armament builds it in the USA from stainless steel with an Ionbond finish.

Key Specifications

Frequently Asked Questions

Which caliber should I choose? Precision Armament says to choose by the actual bullet diameter of your cartridge. A .300 Win Mag, for example, takes a 7.62/.308 device because its bullet is .308 inch.

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.
