Package includes the 16.5 Inch AR-15 Free Float Keymod Handguard plus two 5.3 Inch/13 Slot Keymod Rails.
The all new 16.5 inch Keymod Handguard is our longest ever! Built for longer barreled AR-15s, it extends further down the barrel, providing more rail space and more flexibility in accessory or hand placement. It installs on all standard AR-15 models. The free float design attaches directly to the receiver without coming into contact with the barrel or impacting barrel harmonics. The universal Keymod rail platform accepts all standard Keymod accessories.
The handguard includes the aluminum barrel nut, castle nut, and anti-rotation screw.
Lightweight, low profile design with a 1.75 inch inside diameter; aircraft grade 6061 aluminum construction, only 1 pound in weight; 16.5 inches in total length.
Package also includes two 5.3 Inch/13 Slot Keymod Picatinny Rails for modular attachment of accessories.
Please note that installation of a free float quad rail requires additional tooling and gunsmithing expertise. We recommend consultation with an experienced gunsmith. When installing the barrel nut, we recommend using 30-35 lbs of torque. The barrel nuts are made from 6061 grade aluminum which, although significantly lighter than steel barrel nuts, can be damaged under excessive force. All Monstrum Tactical rail and accessory products are backed by a lifetime replacement guarantee. Monstrum Tactical only sells through and provides support for purchases made through our Monstrum Tactical store.
Please note that installation requires additional gunsmithing tools and expertise. For questions regarding fitment and installation, please view our AR-15 handguard install guides below:
