Home Forums Hunting & Shooting AR and Tactical Rifles 1:12 upper build

I shot this group last Saturday here in Oklahoma in a 18 MPH wind with gusts up to 30 MPH just to see what a crosswind would do. The rifle is a 1/8 twist LaRue 16" pencil barrel shooting 55 grain Nosler Ballistic Tips at 100 yards. Oh and I was using a Trijicon 1-4 Accupower scope. Not a great group but it'll kill any coyote I aim it at and it shot Nosler 50 gr NBT's about the same.

My other pencil barrels are chrome lined 1/7 5.56 chambers and shoot about 1.5" groups and still kill coyotes too. I understand trying a 1/12 twist just to see cause I did it too, bought a chrome lined Colt A1 upper that seemed to be a decent shooter with irons so I put a flat top on it, floated the barrel and went out to see for myself. Shot about 1.5" groups with 50 gr NBT's just the same as the rest of them. So for a light coyote gun, any of them will work but if you want to shoot bug holes, you need a bug hole capable barrel. They aren't pencil barrels and aren't chrome lined as a rule.
