Do any of you folks have opinions on these? Also, I am a bit concerned that I am limiting myself by not using a variable scope, but I am trying build a really tough battle rifle with fewer points of failure and fixed glass seems to fit the bill. Vortex has a PST, FFP model in 4-16X50 that is really tempting me. I am mounting to a bassett mount so I will have co-witness sights. I am trying to put together a 500-1000 meter battle rifle capable of engaging man-sized targets at that range with a good milrad reticle that will allow me to range accurately.
I know there are some very knowledgeable folks on this forum. I appreciate your help!

edited to add I would like to keep the cost on the south side of the $1,000 range. Otherwise I would go Nightforce B.E.A.S.T. and call it a day.
