A good gun store in Colorado Springs or surrounding area?

I am looking for input on any other gun shop besides Specialty Sports. Would any of you guys have some recommendations for me? I have already checked out Sportsmans Warehouse. They don't sell lower receivers. I have also checked out a couple of little mom and pop shops. I just don't want to do business with SS. I have had better customer service at the DMV, compared to SS. Hell, I'd give my money to a store 150 miles outside of town, than give SS my money. Anyway, input would be much appriciated. By the way the lower receiver will be for my MK12/SPRish 6.5 Grendel build that has been in the works for awhile now. Thanks in advance.
