Rainier certainly has some really nice looking billet receivers these days. The new force rail is also pretty spiffy. It has to be super light with the huge cutouts.

Although I am speaking about the .308 version those Rainier Ultra-match barrels are some of the nicest made barrels I have seen. The chamber is a work of art.
I really need to up my photography game to post any pics around here. LOL
That upper is a work of art.

I can't decide whether to go with an entirely new optic, or just cannibalize an existing upper for the optic. Can never have enough optics, but then again, $$$

There is no such thing as reliable at a mile. And most supersonic rounds do not go transonic shortly after 500yds, for instance most 308's you're looking at 1k+yds depending on your barrel length and load. Hell, I've taken my SPR with an 18" BBL and factory 77SMKS out to 900+ even though they were going transonic at around 800+ but it doesn't matter because the round remained stable and bucked the wind better.
Even so if that is your goal then you'll want to look at a magnum cartridge and a bolt since it can handle higher pressures. Your best best would also be a magnum cartridge with a nice gain twist barrel and a heavier pill in something like a 7mm Rem Mag, 6.5CM SAUM, 300WM, or 338 Lapua/Norma/Edge since they're designed for better performance beyond 1K+. The 6.5 Grendel is a great round, but beyond 1K+ its performance will not stand up to the wind as reliably as a heavy.

You don't necessarily need the PRS if you're building out a small frame. I have a UBR on my SPR with a ADM mount and I get a perfect cheek weld. On larger frame AR's because of their design it often requires a higher comb, but on he small frame it isn't necessary most of the time.

Have you used the Rainer extended mag much? Thoughts?
