Description
RCM HK21 Barrel
RCM HK21 barrels are crafted from 41V50 CHF blanks and fully nitrided for optimal corrosion resistance. These barrels are the most cost-effective option to finish your HK21/FMP or HK11 build as the original barrels are rare and command a premium. Barrels come stripped, requiring a flash hider/muzzle device and barrel handle assembly (all components included in FMP21 parts kits).
*Please note: Purchase quantities are limited to prevent resale gouging*
