KAC - Knight's Armament Long FF RAS Mk12 Rail Mod 1 Rail Handguard


The KAC RAS Long rail is the official rail system for the Mk12 SPR Mod1 rifle; given an official NSN designator (1005-01-562-0913) for military inventory purchasing.  Built for the battlefield, this is one of the most durable free float rail systems ever made, and issued en masse to US SOCOM, NSW, and the USMC.  Proven in conflcits around the world, this legendary rail system is available only occasionally when KAC produce a few over contract.

The KAC RAS Mk12 Mod 1 Handguard is the most iconic component of the Mk12 rifle, and highly sought after by collectors who are building clones of the rifle system to NSW/Crane standards.
