Precision Armament Hypertap Muzzle Brake (6.5mm/.264, 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 6.5mm/.264 bore on 5/8x24, the usual thread on 6.5 Creedmoor bolt guns and AR-10s. Precision Armament sizes the bore to bullet diameter, so a 6.5 or 6mm rifle gets a tighter bore than a .30-caliber brake offers. 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.

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.
