Considering a SCAR 17 though.
Dooooo it. (but keep both!)
One day I'll have a 556R.
Great shooting guns, just make sure you get a gen 2!
Can't just have one. Need to have at least two in order to be flexible to the needed requirements. For me it's a PTR-91 (can't afford a real HK 91) and a Sig 516 Patrol.
Love the PTR, are you running any optics besides irons?
