Hi Brian; if you want a Colt - Surplus City is the place to check out. It's on Bustleton Ave. about a half mile above County Line rd. If you desire a Bushmaster, see Dan at Tanners on Rt. 263 just north of Almshouse rd. All the folks at Tanners are good people, I recommend Dan because of his extensive knowledge and he'll give you as much time as you need to make a good decision. If you would like a RRA - Clayton's Guns on Rt.611 just south of the WillowGrove Navel Air Base is the only place around that I know of for a RRA Ar15. See John if you go there. Before you go, ckeck out the various models of RRA rifles you think you'd be interested in and write down the prices, check the Equipment Exchange adds here on AR15.com. Knowing what a good price is will help you get a better deal with him and don't use a credit card - the best price will be with a cash deal. I like the RRA rifles best, but it's a matter of personal preference.
