I've wanted a 458 SOCOM ever since they came out,but always had other things that came first. I went to a gun show today looking to trade my Ruger Blackhawk Bisley 45 Colt for a 40 S&W carry pistol.That didn't happen,but I did finally decide to buy a RRA 458 SOCOM upper to go on the spare lower in the safe. The lower is a DPMS with a RRA 2 stage NM trigger and parts kit,with a Hogue grip and an Ace skeleton stock. I changed out the buffer spring,and then put on the upper.Nice tight fit between the two.I dug out an old scope mount,along with a spare scope-a Redfield Partner 3-12x44,and set them up. Now I'm just waiting for the Starline brass,Lee dies,and bullets to show up.
