I'm looking for a short AR15 and am trying to decide between the LWRC UCIW vs the KAC SR15 with 11.5 barrel. I like the fact that the LWRC's overall length is shorter but overall feel the KAC is better and the ballistics from the 11.5 inch barrel will be better than the 8 inch LWRC one. This will be my first AR15 so I would appreciate input from other's.
