No dimples!

by -

The barrel was a bit rusty out of the packaging. Nothing too bad, just needed a nice wipe down.
<br>The internal milling is nice and shiny in the chamber, and well done at the gas block port.
<br>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

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
