.223 Wylde Chambering

Trinity Force KMX Keymod Handguard

The Trinity Force KMX 12-inch Keymod handguard provides freefloat design with 6061-T6 aluminum construction and modular Keymod slots for direct accessory mounting. The freefloat design isolates the barrel from external pressure, supporting accuracy.

Carbine-Length Gas System

This kit uses a carbine-length gas system with a stainless gas tube and .750 micro low-profile gas block positioned beneath the handguard. The carbine-length configuration is optimized for the 11.5-inch barrel length.
