The Arisaka QD Mount is a low profile design for KeyMod handguards. It features an anti-rotation interface, allowing for 8 different positions, and accepts all standard QD sling swivels, as well as the Geissele/ALG Defense forged QD sling swivel. The use of BCM's patented reverse threaded KeyMod screws allows the mount to be extremely thin. The mount is CNC machined from 6061-T6 aluminum and MIL-A-8625 Type III hard coat anodized. Requires a T15 Torx wrench for installation (not included). BCM KeyMod screws are covered under US Patent 9377274. Made in specialized factories.
