Just installed a Vortex Viper PST 6-24x50 FFP on my Rem. 700 SPS tactical. I used TPS steel medium rings and a TPS 20 MOA base. TPS makes some quality stuff for sure. very nice for the price. Looks to tall for me. Too far off the barrel and too tall for a good check weld. I could put more inserts in the Traid stock pack to get a better check weld but its still to high off the barrel don't you guys think? The medium measure 1.075 and the lows I'm gonna try are .925. Thinks its worth switching the the low rings? Here are a few pics.
