The KAC 45 Degree Offset Aimpoint Micro Mount is intended to be attached to either the 3 o'clock or 9 o'clock rail position, placing the red dot to the side of a primary optic at a 45 degree angle. A quick roll of the rifle is all that's required for the shooter to acquire a useable sight picture through the red dot for close range engagements. Compatible with both T-1 and H-1 Aimpoint Micro optics.
