Product Info for Arisaka Defense Offset Picatinny KeyMod Mounts

The Patent Pending Arisaka Offset Picatinny Mount is a combination of our Offset Scout Mount and Picatinny adapter, and is meant for use with Picatinny based lights like the Surefire X300 or Inforce WML, plus other rail mounted accessories. The Offset Picatinny Mount uses BCM's patented inverted KeyMod screws, which allows the base to be less than 0.165in thick.image

When used on the side mounting surfaces of a KeyMod handguard, the Offset Picatinny Mount places the light at a 45 degree angle and tucks it in for a low profile. Oriented upwards, the light is located at approximately the 1:30 or 10:30 clock positions. Oriented downwards, the light is located at approximately the 4:30 or 6:30 clock positions.

The Offset Picatinny Mount also provides multiple side-to-side mounting positions and is reversible, which allows the user to move the light closer or farther away from the top rail, front sights, or other accessories. Six positions are provided, spanning approximately 0.50in.

The Offset Picattiny Mount is compatible with most KeyMod handguards like the Noveske NSR, BCM KMR, KAC URX4, Geissele SMR MK4/5 KeyMod, Mega MKM, Midwest Industries SSK, and Daniel Defense SLiM and MFR handguards.

The mount is CNC machined from 6061-T6 aluminum and MIL-A-8625 Type III hard coat anodized. Requires a T15 Torx and 5/64in Allen wrench for installation (not included). BCM KeyMod screws are covered under US Patent 9377274. Made in specialized factories.
