Griffin Armament XHP556FC Gate-LOK Flash Comp 1/2x28 5.56 NATO

The Griffin Armament XHP556FC Gate-LOK Flash Compensator delivers dual-purpose functionality as both a standalone muzzle device and quick-attach mount for Griffin's M4SD series suppressors. This precision-engineered compensator reduces muzzle flash while providing the convenience of rapid suppressor attachment through Griffin's proven Gate-LOK system.

What Makes This Different

Unlike traditional flash hiders that only reduce signature, the XHP556FC combines effective flash suppression with compensator ports that reduce felt recoil and muzzle rise. The integrated Gate-LOK mounting system eliminates the need for separate mounts, allowing seamless transition between suppressed and unsuppressed shooting. Construction from 17-4 stainless steel with black nitride coating provides superior corrosion resistance compared to standard carbon steel alternatives.

Key Features

• Gate-LOK quick-attach system for M4SD, M4SDK, M4SD2, and 30SD series suppressors
• 17-4 stainless steel construction with black nitride finish for enhanced durability
• Standard 1/2"-28 TPI threading fits most 5.56/.223 barrels
• Compact 2.21" overall length maintains weapon maneuverability
• 0.863" diameter provides low-profile appearance
• Precision-machined ports reduce both flash signature and muzzle rise
• Compatible with 5.56x45mm NATO and .223 Remington chamberings

The compensator's port configuration effectively redirects gases to minimize muzzle climb during rapid fire sequences. Law enforcement and competitive shooters benefit from faster target reacquisition, while the flash reduction capability maintains shooter concealment in low-light conditions. The nitride coating withstands extreme temperature variations and chemical exposure without degrading performance.
