Area 419 Sidewinder Magnum Self-Timing Muzzle Brake .338 Cal Black Nitride 5/8-24

Area 419 Sidewinder Magnum Self-Timing Muzzle Brake – .338 Cal | Black Nitride | 5/8-24

The Area 419 Sidewinder Magnum is a self-timing muzzle brake chambered for .338 caliber barrels with a 5/8-24 thread pitch, finished in black nitride. It is manufactured from heat-treated 17-4PH stainless steel and made in the USA on CNC machines in NW Ohio.

The Sidewinder's self-timing system is built around a universal adapter that threads onto the barrel using a 13/16" wrench. The brake and collar assembly then left-hand threads onto the adapter. Once the brake is rotated to the desired orientation, it locks onto an internal taper. The knurled collar is then tightened by hand — no additional tools required. Area 419 states that this system allows the brake to be removed and reinstalled without requiring a zero change.

Key Features

• Self-timing design: brake locks onto an internal taper and will not rotate during collar tightening
• Simple round knurled collar tightens by hand — no tools needed to time the brake
• Rearward-facing port design with proprietary progressive port sizing — ports decrease in size moving away from the muzzle to manage overall length
• Proprietary port design controls muzzle rise without top porting
• Face of brake engraved with caliber designation and a horizontal reference line to aid in leveling
• Material: heat-treated 17-4PH stainless steel
• Finish: black nitride (universal adapter is also black)
• Brake OD: 1.125" | Collar OD: 1.275"
• Overall brake length: 3.35" | Adds approximately 2.75" to barrel length

• Thread pitch: 5/8-24
• 100% Made in USA

Area 419 notes that the Sidewinder features one additional port and a larger diameter compared to their HELLFIRE brake, and that suppressor mounts compatible with the Sidewinder will be available in the future.
