Product Description

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 0.50″.

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.
