Purchased a Remington 700 from them through a listing on GunBroker. Price was fair, shipping was fast, and overall great buying experience. They have a wide and ever changing range of firearms so anyone would find something they’d like.

Got an amazing deal on a Springfield Armory loaded 1911 with amazing service! Everything went perfect and highly recommend them and look forward to buy here again!

I won a Henry 30-30 from a local charity auction, a fine lever action rifle. I saw the D4 leather knuckle wrap lever cover on a friend’s Facebook page, asked him about it. With his response, I immediately ordered one from Amazon, and I am happy I did. Stitching it up was simple, and the comfort and beauty of the brown leather compliments the beauty of my Henry’s walnut stock.A very satisfied customer.

1756225146

Very satisfied with D4 Guns. Purchased a pistol from them on GunBroker and they make it very simple and easy with great communication. The gun was shipped out and tracking info provided within 24 hours of purchase, which really impressed me. Additionally, their pictures and details are solid so that you know exactly what you're getting.

1747312217

This was my first used gun from GunBroker-- D4 did an excellent job in putting together a detail description of the firearm. The firearm arrived clean, oiled and ready to shoot out of the box (I literally took it to a match three hours after picking it up). All the paperwork, locks, and peripherals were included. This was a better than expected experience. Five stars and absolutely recommend D4 for purchases!
