Griffin Armament XHP762FCM Gate-LOK Flash Comp Black Nitride 17-4 Stainless Steel 5/8-24 tpi Threads XHP762FCM UPC 791154081549
Product Description
The Griffin Armament GATE-LOK 7.62mm Flash Comp (XHP762FCM) is a hybrid muzzle device designed to deliver exceptional muzzle rise compensation and flash suppression while serving as a fast-attach mounting platform for GATE-LOK silencers. Engineered for .30 caliber rifle platforms (.308 Win, 7.62x51mm, 300 Blackout, and 6.5 Creedmoor), the Flash Comp balances recoil reduction with low-light flash signature reduction.
Precision CNC-machined from 17-4 PH stainless steel and finished in a black QPQ Nitride coating, the XHP762FCM is built to withstand extreme thermal expansion, gas erosion, and hard duty use. Measuring 2.77 inches in overall length with an outer diameter of 0.863 inches, it incorporates top expansion ports to drive the muzzle downward during rapid firing and tuned front tines to disrupt expanding propellant gases.
Threaded in standard 5/8x24 tpi, the Flash Comp serves as a direct interface for Griffin Armament 30SD series silencers, M4SD series silencers (with 7.62 compatibility), and the GATE-LOK QD Blast Shield. Complete with a precision timing shim set, it provides armorer-grade lockup and muzzle stability on tactical, hunting, and precision carbine setups.
Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Threaded 5/8x24 tpi for .30 caliber, .308 Win, 300 AAC Blackout, 6.5 Creedmoor, and .270 barrels. Functions as a fast-attach mounting interface for Griffin 30SD, M4SD series silencers, and the GATE-LOK QD Blast Shield.
- Perform a complete firearm safety check: drop the magazine, lock the bolt rearward, and visually inspect the chamber to verify zero live rounds are present.
- Thoroughly clean barrel muzzle threads and inspect for dirt or carbon build-up.
- Select the proper combination of included timing shims to achieve correct top-port indexing alignment (do not use crush washers for suppressor mounting).
- Apply a small drop of high-temperature threadlocker (Rocksett) or anti-seize to barrel threads.
- Thread the XHP762FCM onto the muzzle hand-tight, then use an armorer wrench to torque to 25–30 ft-lbs.
- Verify suppressor alignment with an alignment rod prior to live-fire suppressed shooting.
