    I have been looking for this rifle for some time and finally found it reading the Colt ar15 resource, they sent me to Arms Unlimited and it was priced right! I'm waiting to get a M45A1

    Good pricing, solid inventory and customer service was some of the best I’ve had. Gun shops are notorious for s*** service and AU is by far one of the best. Buy with confidence
