    Magazines need work

    Posted by Bill on May 7th 2017

    Review of Diamondback DB15. Initially charging handle hard to function. 1. Sharp edges caused sticking/jamming. 2. Could not pull bolt back enough to lock. 3. could not lock charging handle back to fire position. REMOVED all sharp edges and lubricated charging handle and bolt along with all instructions for lubing the rifle and worked fine. Took to range and no problems with BRASS ammo. Tried TulAmmo and could not cycle round into chamber, had scraping on round from bolt but no chambering of the round. (Still in magazine as when round loaded into magazine). Magazines were from same manufacturer and same model. When trying to strip the rounds from the magazine, the rounds were stuck and really hard to remove. All magazines were doing the same thing. Tried all magazines in another AR15 with same results of bolt not stripping rounds from the magazine. Checked magazines and found all had burred sharp edges that were digging into the shell casing of the TulAmmo preventing the shells to be stripped from the magazines. Back home took file and scraper to the edges and found also that the stiffening indentation on the sides of the magazines had to be filed down also to be able to strip the rounds completely from the magazines with the same effort as with the brass ammo. Seems the butt of the TulAmmo casing is larger. Would rate higher than average, but expected better quality control from Diamondback and the manufacturer of the magazines they provide with their rifle. Now that the (bugs that I have found) are worked out, the rifle is satisfactory and is functional.

    A Most Satisfactory Firearm

    Posted by SawtoothSam on Aug 13th 2013

    I was in the market for a new AR. But this time, I wanted something NOT black. Frankly, every time I open my gun safe and peer inside and see all the black rifles and shotguns staring back at me, I cringe at the thought of adding yet another ebony bang-stick to my collection. So when I saw the Diamondback FDE on the Impact Guns website, it just plain caught my fancy. To be sure, I was hesitant to shell out money for something called "Diamondback," since the company had very little in the way of a track record. But every company has to start somewhere. And let's face it, the Diamondback AR offered that appealing FDE finish. And while it didn't have all the bells and whistles I normally opt for, it had all that I really needed. And it was there, on the website, in stock, and ready for shipment. And not only were both its lower and upper receivers finished in FDE, the same was true of the gun's aluminum free-float handguard with its integral rails. So I bought it. And I haven't regretted the purchase even once. Cleaned it, slapped on Magpul flip ups and took it to the range. Pushed 200 rounds through it the first day without a hitch, except that I ran out of ammo way too soon. Enjoyed shooting it so much, I went back the next day with 400 rounds. It ate everything I fed it without a hiccup. My eyes aren't the greatest anymore and my groups reflected it using iron sights. So for my next range trip I mounted a red dot and my groups improved. But red dots aren't the best for precise shooting, anyway. I got the distinct impression the optic wasn't doing the rifle justice, so I replaced the red dot with a Nikon P-223 3-9x40mm BDC. Since then I've put over 500 more rounds through it (various brands and styles of ammo). I still haven't shot the coveted 1 MOA group at 100 yards, but I'm getting close, which is better than I shoot with any of my other ARs. So far, not a single FTF or FTE. It even digests steel-cased ammo like Wolf, Tula and Herter's without complaint. Oh, and for what it's worth, after one or two range trips, I tossed the stock that came with the gun (it wobbled annoyingly) and replaced it with a Magpul CRT. Money well spent. Maybe I just got a superb sample. It happens. Maybe the gun will break tomorrow. Could be. But until then I'm running it pretty much as it came from the factory and I'm eminently pleased with it. Haven't shot a black gun in weeks.

    Good by for the money

    So far im very pleased with my Diamondback Db-15 only thing wish was gun dealer would of had the FDE but i have installed the magpul FDE stock, hand grip & trigger gaurd. Purchased the gun to hunt coyotes with. Its getting the Job done. Put burris rail on it with Simmons whitetail 6.5x20x50 on it with a light and laser on quad rail. 100 yards a 5 shot group with 55 gr hornaday can be covered with a quarter. Gun's well work the money compared to some of the other AR i have shot.

    Best on a budget.

    Posted by Anonymous on Dec 14th 2012

    Only put about 100 rounds through it, but so far am very impressed. Used PMC 5.56 x-tac. This is my first ar style rifle I've owned. I was definitely attracted to the fact it was under 1000 dollars and was an aluminum upper and lower. I also really like how it is not completely filled with rails. But there is still enough for you to do a fore grip, laser, flashlight, and scope, assuming none of them are combos. I was told that Diamondback is from some guys from Kel-Tec, which I was at first skeptical, but got over it pretty quick.
