Machined from heat-treated 17-4 PH stainless steel and finished in Melonite QPQ, this flash hider delivers exceptional corrosion resistance, surface hardness, and long-term durability. At the heart of the design is the proprietary DUAL-LOK quick-detach mounting system, which integrates 60 machined grooves on the muzzle device interface - doubled by the mount's two locking positions, phase-shifted by 3 degrees to create 120 effective locking positions. The result is a rock-solid, no-wiggle fit that minimizes point-of-impact shift when transitioning between suppressed and unsuppressed configurations. The high-efficiency 3-prong flash suppressor design provides outstanding flash reduction without ringing or pinging under fire. Anti-resonance flutes and wrench flats further enhance reliability and ease of installation. The unit measures 2.34 inches in overall length with a 1.07-inch diameter, and weighs only 3.3 ounces. It is also pre-drilled to support pinning and welding on 14.5 to 16-inch barrels, making it fully compliant-capable for NFA builds.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Highlights\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDUAL-LOK Quick-Detach System:\u003c\/strong\u003e 120 effective locking positions via 60-groove interface phase-shifted by 3 degrees for a rock-solid, repeatable suppressor mount with zero wiggle.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHigh-Performance Flash Suppression:\u003c\/strong\u003e 3-prong design delivers outstanding flash reduction without ringing or pinging, supporting accuracy and stealth in dynamic environments.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePremium 17-4 PH Stainless Steel Construction:\u003c\/strong\u003e Heat-treated and finished in Melonite QPQ for superior surface hardness, corrosion resistance, and extended service life.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAnti-Resonance and Precision CNC Machined:\u003c\/strong\u003e Anti-resonance flutes and wrench flats provide secure alignment, easy installation, and reliable performance under sustained fire.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePin and Weld Ready:\u003c\/strong\u003e Pre-drilled for pinning and welding on 14.5 to 16-inch barrels, enabling compliant permanent installation when required.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecs\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Griffin Armament\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number (MPN):\u003c\/strong\u003e DL225FH1228\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 689396837812\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCaliber:\u003c\/strong\u003e .223 \/ 5.56\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Pattern:\u003c\/strong\u003e 1\/2x28\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length:\u003c\/strong\u003e 2.34 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter:\u003c\/strong\u003e 1.07 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 3.3 oz\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Heat-Treated 17-4 PH Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Melonite QPQ\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Black\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLocking Positions:\u003c\/strong\u003e 120 effective (60-groove interface, 3-degree phase shift)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDesign:\u003c\/strong\u003e 3-Prong Flash Suppressor\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePin and Weld Compatible:\u003c\/strong\u003e Yes (pre-drilled for 14.5 to 16-inch barrels)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCondition:\u003c\/strong\u003e New\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cem\u003eDisclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
