The BCM KMR ALPHA KeyMod Free Float AR-15 Handguard – 15″ provides superior strength and durability thanks to its 100% aluminum construction. The hardcoat anodized finish protect the handguard against corrosion and reflection, while the proprietary mounting, indexing, and locking system keeps the rail in place under heat generated from the barrel nut. The KeyMod mounting slots on seven sides give you ample space for attaching your favorite accessories, and the continuous Picatinny rail ensures compatibility with a wide range of optics and other devices.

Notice from the manufacturer:

“Please note: Nylon/Polymer Picatinny rail sections are for NON-load bearing accessories only. For load bearing accessories, we recommend aluminum Picatinny rail sections. Do NOT exceed 20 in/lbs. when securing KeyMod Fasteners on Polymer accessories. Aluminum Picatinny rail sections may be torqued to 30 in/lbs”
