The revised Gen 3 Gate-LOK stealth flash hider delivers exceptional performance for M4SD sound suppressor users seeking a superior alternative to A1 and A2 birdcage flash suppressors. Designed for optimal suppressor fit, it significantly reduces flash signature and minimizes muzzle climb for improved control. Extensive research and development led to a high-performance 3-prong flash hider engineered to suppress flash as effectively as possible while eliminating unwanted resonance. Precision CNC-machined and ground to exacting standards, it is crafted from precipitation-hardened 17-4 stainless steel, ensuring outstanding resistance to heat, corrosion, and wear. Compatible with the M4SD series Gate-LOK suppressor interface, it comes complete with a shim set and an over-travel stop washer. The muzzle device is pre-drilled for pinning and welding onto a 14.5 inches barrel, making it an ideal choice for achieving a 16 inches non-NFA carbine length. For proper installation, the over-travel stop tab should be positioned at the bottom of the muzzle device at the 6 O'clock position.
