iRayUSA Rico Micro Dovetail Picatinny Shoe Black IRAY. The synergy of these two mounting formats creates a system that is more accurate and versatile on a rifle while maintaining all dovetail capabilities on a helmet. The PICTAIL is compatible with standard dovetail receptacles used in helmet mounting interface hardware made by Wilcox KVC and others. The counterpart to the dovetail side of the PICTAIL shoe is MIL-STD-1913 picatinny rail specially designed with one slot that interfaces with the ADM MQD mount. The PICTAIL and MQD mount work in tandem to achieve an adjustable footprint on any standard picatinny rail. In standalone optic mode they produce over 4.5 inches of rear offset and when reversed for use in clip-on mode the MQD and PICTAIL shrink the rear offset to just 1.5 inches. In clip-on mode the required forward rail space is just 4 rail slots in front of a day optic making the PICTAIL and MQD the perfect combination for shorter platforms like SBRs and pistols. iRayUSA partnered with American Defense Manufacturing to produce the PICTAIL and MQD delivering ADM's gold standard picatinny mounting solution with an innovative lighter and faster dovetail design for faster helmet transitions.
