I may end up with a SBR but I like the 16" barrel length. I'm not a great long distance shooter (or short distance shooter to be honest) so decreasing the barrel length would not help my "skills".
Not really true. I SBR'd mine and went with the 10.5" select barrel from Rainier Arms and it shoots a lot better than my 16" spikes barrel I had on it before. Honestly if you're shooting off hand in the field that can hanging on the end of the 16" barrel is going to tire your arm and make you less accurate pretty fast.
Here is a pic of my 10.5" barrel SBR with a 9" CMMG KeyMod Rail system and the YHM Phantom 30 cal can. The target is the first group at 50 yards with a Aimpoint T1 RDS. The other pic is what it now looks like with the 5" dedicated 223 can instead of the 30 cal can. Huge difference in size and weight between the two.
