POF 00309 Triple Port Muzzle Brake 5/8x24 .308 AR Black Nitride

The Patriot Ordnance Factory 00309 Triple Port Muzzle Brake transforms .308 AR-platform rifles by significantly reducing felt recoil and muzzle rise during rapid fire sequences. This black nitride-finished brake channels expanding gases through three precisely machined ports to deliver superior recoil mitigation compared to standard flash hiders or compensators.

What Makes This Different

The triple-port configuration directs gas flow at optimal angles to counteract both vertical muzzle climb and rearward recoil forces simultaneously. Each port features chamfered edges and uniform dimensions that ensure consistent gas redirection across all firing conditions. The black nitride coating provides enhanced corrosion resistance and surface hardness beyond standard phosphate finishes, extending service life in harsh environments.

Key Features

• Triple-port design reduces felt recoil by approximately 40-50% compared to standard muzzle devices
• 5/8"-24 TPI threading fits .308 Winchester and 7.62x51mm NATO barrels
• Black nitride finish resists corrosion and maintains appearance under heavy use
• Precision-machined steel construction handles high-pressure cartridges reliably
• Compatible with AR-10 and SR-25 pattern rifles chambered in .308/7.62x51
• Low-profile design maintains sight picture and weapon balance
• Easy installation with standard armorer's tools

Competitive shooters benefit from faster follow-up shots during rapid-fire stages, while tactical applications gain improved control during sustained engagements. The brake maintains effectiveness across temperature ranges from sub-zero conditions to desert heat. Hunters appreciate the reduced flinch response that improves shot placement on medium to large game.
