5/5 – Outstanding Service, Great Prices, and a Cool Personal TouchThis was my second time ordering from D4Guns.com, and once again, they exceeded my expectations. I ordered 300 rounds of 12-gauge shotgun shells, along with 9mm, 5.56, .223, and .45 ACP ammo. Everything arrived quickly, in perfect condition, and exactly as advertised. Their shipping is incredibly fast my orders have always been fulfilled within 24 hours.What really stood out this time was a small note I left during checkout. I half-jokingly asked if they could throw in some stickers because I thought it would be cool. Not only did they notice it, but they actually included a full sticker page and it was awesome! That kind of thoughtful touch is rare these days.Their customer service is top tier. They answer the phone, are completely transparent, and no matter how detailed or drawn out my questions were, they always took the time to respond professionally and thoroughly.I’ve compared prices across multiple sites, and D4Guns consistently has the best deals especially for the quality of ammo you’re getting. Between the reliability, speed, and down-to-earth customer support, I honestly don’t see myself shopping anywhere else.Highly recommended. This company has earned my loyalty.(Check out the stickers)

Won an action for the first time. I was unsure of the next steps after submitting my info and payment, I called D4 and they were very helpful in answering my questions and promptly completed my order. Shipping was fast and uneventful. Overall a great experience. Will definitely buy from them again.

Once I won my auction for the item I wanted, the communication was very fast and clear, the item shipped quickly and arrived with no problems. I will definitely be buying from D4 Guns again. Recommended!

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!

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!

D4 is awesome. All their guns are among the more desirable, and they are all penny auctions!. I purchased a classic CZ 75 B 25 Anniversary Edition and a Walther PPQ Q4 SF. Both were in great shape and D4 communicates well and ships to your FFL the day after you win the auction. Highly recommend!!
