Notes from the Bunker: Choosing an AR-15
Survival & Emergency Preparedness: Choosing an AR-15
My rifle is a Colt AR-15A3 Tactical Carbine. The one feature I may
change on it is the barrel, it’s a 1:9 twist HBAR. I’d prefer a
lightweight 1:7 twist barrel. Based on what I’ve read by instructors
who see lots of ammo go downrange, Colts tend to be the most reliable
of the major manufacturers. You pay a premium but on a defensive
rifle reliability is the single most important factor.
