No dimples!

by -

The barrel was a bit rusty out of the packaging. Nothing too bad, just needed a nice wipe down.
The internal milling is nice and shiny in the chamber, and well done at the gas block port.
There are no dimples for set screw type gas blocks, but the finish is coarse enough to hold it in place when torqued.

Solid grouping. No dimple.

I bought this barrel and ran it with an anderson upper atop an aero lower. I’m achieving very solid groups. Only down side I see to owning one of these is it does not come pre dimpled. But as the gentleman above stated, it’s coarse enough to hold. I like it. Would buy another.

Great quality to cost


This is an excellent barrel for the price. I am getting sub moa at 100 yrds with several different brands of ammo and some Russian rounds. I would not use Geco for accuracy its best is 2.5 in. recommend the barrel though its a little heavy but not unmanageable

Great barrel, well worth the purchase.


I used this barrel on an Anderson upper and the barrel shoots great. I have managed at least 200 rounds of so far. I lubed up my upper and have only used steel cased rounds.

great budget build barrel

by -

Wanted to do a AR-47 build on a budget and this barrel fit the bill. Already have the 10 inch version of this barrel and that was a awesome barrel. And so is this one!!!

Good Barrel

This is a good lookin' barrel.
I especially like the light weight 1.62 lbs


by -

1.6 lbs. Just right! Nitride finish.

DB Ar15 7.62x39 Barrel a Winner!


These Diamondback 7.62x39 Ar barrels are the Real Deal. I have the 16" and the pistol length barrel. Both are very accurate. Want to buy another one so I can change out the barrel I have on another upper I have in 7.62x39.

snake bite

I love to build with Diamondback products. This barrel is a perfect mate for a BCA upper. Primary Arms got this barrel to me fast and without incident, it arrived in perfect condition..
