Just picked up a slightly used Socom 16 with 5 CMI mags and the stock 10 rounder. I'm super excited to shoot it but I could only afford 20 rounds plus the gun! Now I'm saving for ammo and a few choice upgrades from Sadlak. I've already taken it apart twice and cleaned and re-greased it and I'm busy trying to figure out how to use a model 1907 sling! I've owned many handguns over the years and a bunch of .22 rifles but this is my first major caliber rifle! I'm looking forward to learning a lot!
