[45 / 20 / ?]
I thought I wanted an AR, and I still do, but I want a battle rifle more. I don't want the extra recoil or cost of 7.62 for this particular role, so where does this leave me? I want something clean and sturdy looking like a battle rifle, yet cheaper to feed and softer recoiling like an AR. SIG 556 is the closest thing i've found. SIG 55x pics and discussion in here.
