I have a Remington SPS Model 700 in .300 Remington Ultra Mag I have been thinking about parting with, since I use my Sako TRG-S .30-.378 WBY Mag exclusively for everything. Plus I have an old, trusty Rem 700 in .300 Win Mag that is tried and true that I will never part with. I have been looking for a new upper for my AR, (not a .223) but could always use another AR type rifle to play around with and/or trade for a new upper. Let me know what you are thinking.
