I've been thinking about this for a while, and it's now time for me to decide between the following two rifles. These are primarily for range/plinking, and extreme home defense scenarios (although in all honesty I would probably pick up my shotgun in that situation). The two rifles in question are the KelTec SU-16C (Kel Tec) for $549 + tax, and the Bushmaster Carbon-15 (Bushmaster - Home Defense & Recreation Rifles) for $699 with a Bushnell TRS-25 red dot scope. Both rifles are lightweight, use 5.56 ammo, and take AR mags. More importantly, both are in my price range. If these were the only two (2) rifles you could pick from, which would you choose?
