Area 419 Hellfire Self-Timing Muzzle Brake - 6.5mm, 5/8"x24, Raw Stainless Steel The Area 419 HELLFIRE Self-Timing Muzzle Brake is not just another copy of existing self-timing brakes. Engineered from the ground up, it delivers exceptional recoil reduction, unmatched ease of installation, and outstanding versatility for precision rifle shooters. Independently tested side by side with leading competition brakes, the HELLFIRE demonstrated 52% recoil reduction on a 6.5 Creedmoor test rifle, outperforming some of the most popular brakes on the market by approximately 4%. This 6.5mm variant is compatible with any bullet caliber up to and including 0.264" (6.5mm), including 257 and magnum cartridges. Machined from heat-treated 17-4PH Stainless Steel on state-of-the-art CNC machines in Northwest Ohio, this brake is 100% Made in the USA. The raw stainless finish is paired with a black universal adapter for a distinctive look and lasting durability. Product Highlights 52% Recoil Reduction: Rearward-facing ports and a proprietary port design deliver industry-leading recoil management without top porting for muzzle rise control. Self-Timing System: The brake locks onto a taper and will NOT rotate as you torque the collar - no tools required and no guesswork about port orientation after installation. Excellent Return to Zero: Removal and re-installation of the brake requires no zero change, making it ideal for field-use precision rifles.
