Building an AR-10 with VSeven parts-matching using HIPERFIRE HIPERTOUCH ECLipse (nickel) to color match it as well. VSeven are well built, no argument there, but would say this selector is their weak point. This selector is the right-hand variant, while the other one, same design, is the ambidextrous (3J2-FSS-V7-1109-TI-AMBI) variant. But the differences don't end there. The "barrel" of the ambi variant, is not smooth or cylindrical, it is "triangular" (three sided) if you will, for the purposes of selecting the 57/90 feature. This is fine for mil-spec (or similar) triggers, but the issue with this is when you are using the finicky HIPERFIRE triggers, there's a protruding "wing" that stretches out from the spring-frame trigger and rests on the barrel of the selector. So if the selector isn't smooth and cylindrical, the "wing" of the trigger will not glide smoothly over it, causing the selecting action to grit, grind, or slap on the three-faced barrel. I figured this selector would be best tested used on mil-spec parts, so I did. Big improvement but nowhere near the feeling of a mil-spec "snap" or "click" while gliding in-between. Upon inspection I noticed the drilled "channels" and "holes" of the selector of which the safety selector pin contacts with, isn't as smooth or machined as near as the milspec. Liberally used oil and a KNS nitride safety selector pin and the selector action was not smooth, but springy, and smooshy with a little bit of play on either the SAFE or FIRE ...
