JK Armament MD HD BE12 7/8x32 TPI Muzzle Device 12 Gauge Black

The JK Armament JKMDHDBE127/8X32 muzzle device delivers precision-engineered recoil management and muzzle control for 12-gauge shotgun platforms. This 17-4 stainless steel component features 7/8x32 TPI threading and a durable black finish that withstands harsh conditions while maintaining consistent performance.

What Makes This Different

Unlike standard muzzle devices that prioritize flash suppression alone, this JK Armament unit combines recoil reduction with improved follow-up shot capability. The 17-4 stainless steel construction provides superior corrosion resistance compared to standard carbon steel alternatives. Internal geometry directs gas flow to reduce felt recoil by approximately 15-20% while maintaining proper cycling in semi-automatic shotguns.

Key Features

• 17-4 precipitation-hardened stainless steel construction for maximum durability
• 7/8x32 TPI threading fits most 12-gauge shotgun barrels
• Black oxide finish resists corrosion and reduces glare
• Precision-machined ports optimize gas redirection for recoil management
• Compatible with standard 12-gauge ammunition loads
• Thread protector design allows secure attachment without timing
• Maintains proper barrel length for legal compliance

Field testing demonstrates consistent recoil reduction across various ammunition types, from light target loads to heavy waterfowl rounds. The device maintains zero shift when properly installed and torqued to specification. Competitive shooters report improved split times in rapid-fire scenarios, while hunters benefit from faster target reacquisition. The stainless steel construction handles extended shooting sessions without degradation in performance.
