Colt SP1 vs Colt AR15-A2


Subscribe to Channel

We have a little shoot-off challenge here between the original Colt SP1 rifle with a 1:12 twist and a later Colt Sporter Target Model (aka A2) with a 1:7 twist. There's a lot of discussion on the net as to which rifling twist is the best for accuracy using 55gr ammo. Both rifles are fired with iron sights and the results are entertaining.
