Ok, I have about $2000 coming to me via check. My plan is to drop it all on shooting equipment. Here are a couple of options. First, I can basically shoot the whole wad on a Vortex Razor 5-20x50 scope. Secondly, I could get a Vortex PST FFP, and a used Sig 556. I could also go with the Sig, the PST in SFP and get a used Leica 1200 ($350). Right now I have a Vortex Crossfire on LR rig, but would like to upgrade. Also, I don't have an AR type carbine in the collection. I don't shoot comps. and no ones life depends on the scope. Any advice?
