Comstock Armory 4-Prong Flash Hider 5/8x24 30 Cal - Plan-B Mount

The Comstock Armory 4-Prong Flash Hider is a 30 caliber muzzle device built from high-strength 17-4 PH stainless steel with a durable black nitride finish. Standard 5/8x24 threads make it a direct fit for 30 caliber barrels chambered in 7.62/.308 and 300 BLK, and the 4-prong design is rotationally symmetric so no timing is required during installation.

This flash hider doubles as a Plan-B compatible suppressor mount, working with common .900"-24 adapters such as the Q Plan-B and Rearden Atlas for quick attachment and removal of compatible suppressors. The body features 13/16" wrench flats for easy installation, and the compact overall length adds roughly 1.36" to the muzzle. The unit measures approximately 2" overall and weighs just 1.9 oz.

Offered in New condition, the Comstock Armory 4-Prong Flash Hider is a versatile muzzle device that provides both effective flash suppression and a clean direct-thread mounting platform for today's 30 caliber precision and defensive rifles.
