Im hoping to build a clone M40a3 (ok, have it built by GAP) over the next year or so. I was looking at ways to outfit it and still be clone correct. Does anyone know the specifications of the Schmidt & Bender 3-12 they used to run on the USMC rifles? I know its a PMII, but are there different generations of PMIIs, do they run illumination, which reticle do they use (I would imagine Mil-Dot/P3)? Also, I have seen some A3s with the night vision rail up front. Was this something the Corps did while transitioning from the A3 to the A5? Thanks!
