Diamondback Firearms DB15 M4 Carbine AR-15 Semi Automatic Rifle 5.56 NATO - Blue/Black, 16" Barrel, Synthetic Stock

Overall great budget gun. 5,000 rds through it with no issues. Buds is always the best way to go.

i would give this a 5 rating, but i feel i paid a bit too much for it, my fault, but it is quiet a bit cheaper now, and for the lower price, its an even better deal, shoots straight, well built, have only put brass trough it at this point, but flawless operation.

I’ve had this gun for over two years now and not one malfunction or problem with the gun I love this gun and I would recommend it to anyone

Its a good gun for the price. Only complaint is the quad rails are huge.

cycles everything very tight groups at 100 yards

The Diamond back AR-15 is the first rifle sized weapon that I have purchased so my comments are from a new and inexperienced purchaser of such a firearm. I have much to learn about the weapon going forward. The AR-15 is easy to use from a lefties point of view. It isn't a heavy weapon, the recoil isn't bad at all when fired. The 30 magazine firing is concise. As a semi automatic weapon the trigger firing works very well. Allowing the operator to increase or decrease the amount of rounds the AR-15 fires at the operators pace. I have fired off full metal jacket 223 55 grain rounds at my local indoor gun range and must say that while I do enjoy firing the AR-15 I have recently purchased a scope for it to improve my accuracy with the target practice shooting sessions. The AR-15 and the Diamondback is a solid weapon which is sold at a very good price point. The AR-15 will not let you down this I'm certain of. Do your due diligence, there are many You Tube videos on the Diamond back AR-15 and the competitor brands to watch along with many tips being given from many experienced gun owners to make an informed purchase decision.

Fantastic gun at a fantastic price. I mounted a 1-6 Vortex optic on it and it shoots sub moa at 50 yards. The handguard, stock, and charging handle are cheaply made but if you don’t want to replace them, the gun is still great. I put about 300 rounds through it right out of the box with no issues before replacing the handguard with a Mentium USA 15” keymod, the charging handle with a seekins precision charging handle, and the stock with a MFT minimalist stock. Also replaced the bolt carrier with a Falkor bolt carrier. The gun is still great without those upgrades, just how I set it up.

Just purchased this gun and its amazing. Extremely light weight and very accurate. I highly recommend this weapon. Thanks buds for the fast shipping and excellent service. I look forward to doing more business soon

Diamond back db15 223/5.556 great bang for the buck. Ran 300 rounds thru and no issues. Added iron sights and also a red dot. Very accurate. Highly recommend it.

I was a little skeptical of this firearm because of its low price, but after putting 200 rounds through it with very little maintenance and having zero FTF's as well as very good accuracy, I am convinced that this rifle could compete with those that run $1000 or more. I am now a fan of Diamondback Firearms for life.
