Precision Armament Hypertap Muzzle Brake (7.62mm/.308, 5/8x24)

The Hypertap is Precision Armament's highest-reduction brake: a reverse-venting hybrid baffle design with convergent-divergent ports that the maker rates at up to 84% recoil reduction, nearly 10% more than its M4-72, while keeping 35-degree baffle angles and generous bore clearance. An integral timing nut replaces shims and crush washers, so the brake times and tightens with an adjustable wrench or the included spanner tools, and the pilot holes can be drilled out to tune gas bias against muzzle rise.

This row is the 7.62mm/.308 bore on 5/8x24. Precision Armament sizes muzzle devices by bullet diameter, so it also covers .300 Win Mag and other .308-diameter cartridges on a 5/8x24 muzzle. Choose the Slim Body (0.90 inch, 2.54 inches) for light contours or the Standard Body (1.09 inch, 2.94 inches) for heavier barrels; Precision Armament measured 70% reduction with 147 gr .308 FMJ through the Standard Body and 67% through the Slim.

Reverse venting is how it reaches that number, and it sends blast and concussion back toward the shooter. Precision Armament recommends a barrel of at least 14.5 inches and publishes a muzzle brake safety memo for anyone running it shorter. It is heat-treated stainless with an Ionbond CrCN finish or bare stainless, made in the USA.
