I bought this directly from Servos Custom Firearms and it's purposely machined to fit a Seekins PH3 (notched on the bottom to accommodate the slightly proud M-LOC rail and QD mount). VERY high-quality machining. Brand-new condition with ZERO scratches. I attached it to my rifle, and it went in the safe. Just decided not to run full ARCA now, so time to find it a new home.
