Trinity Force 12" Argon Keymod Rail Handguard AR-15
The Argon Keymod Rail features a slim profile for improved ergonomics and oversized cutouts for our lightest rail system yet.
With a static top rail optimized for mounting optics and multiple contact points for a hex key mounted modular rail system on the sides and bottom, the Argon Rail is the ideal solution for any AR15 owner looking to shed some pounds from their rifle, and gain some mission flexibility.
It uses a hex key secured barrel nut clamp and proprietary barrel nut for even more weight savings and easy installation.
FREELOK Clamping System US. PAT. NO. 9,389,043 B1
The Argon Keymod Rail features a non-indexing barrel nut and clamping system (FREELOK) that utilizes free floating tabs to secure the rail to the receiver.
FREELOK provides both frictional and mechanical locking forces to create a rock-solid bond between the rail and barrel nut.
