I bought most of my first firearms here and also did a bunch of transfers! Everyone that worked here made me feel like I could always browse for awhile without getting pushed out. Always informative and could even order whatever I wanted. Also Jroc which is in the same building is another good dude! Same great service in the same shop. I need to come back, fell out of the loop after the stupid ban, hope to return before I move to a more gun friendly state in 26'. Always fun to talk to and can help with classes and other things! Thanks guys and girls!
