These guys have great selections and keep the bidding honest. This was my second purchase through them and they were fast and responsive on both occasions. Shipping costs were average so take that into consideration when bidding. It's been a hassle-free experience and at the end of the day, that's what counts. Also, their used gun selection has ample photos to determine condition before you bid. Pro-quality close ups. I remain a happy camper!
