Pretty dang good barrel. & PA- Write some reviews on products if they aren’t rated

by HAbel, from TX, United States Written on May 19, 2025
Got the barrel on sale for 250 in 13.9. It’s pretty dang smooth, nice balance, tapers down like a Core does around the gas block to roughly a .625 is gas block. I’m not sure how they can mill that thing into a barrel but it’s impressive. Barrel nuts slip over the top of block. I can easily see it shooting sub moa like reviews have stated but I have not grouped it yet. When I can I will get back with a review of the barrel groupings bc that’s what matters. Reviews are helpful and if a product doesn’t have some reviews. Take some time to help the next guy out.we’re all in this together.

Monobloc barrel 1k review

by GlockMan, from VA, United States Written on September 12, 2024
I now have 1k rounds through my monobloc barrel and i friggin love this thing. I have heard of situations on forums where people’s set screw and pinned gas blocks move on them after high round counts, rendering the rifle useless. This fear is what drove me to this product and dear lord is it worth the price. This is the highest quality barrel i have ever touched. From the machining to the finish and chrome lining. It is all perfect! It out shoots all my other chrome lined barrels from more well known brands as well. With the gas block being one with the barrel permanently, this barrel eliminates a variable while not compromising any other feature. Love it.

Machinist’s Review of Monobloc

by Ochoa, from FL, United States Written on September 11, 2024
Spectacular barrel and worth every penny. I am a machinist by trade so knowing what goes into the manufacturing of a barrel like this, considering the gas block is milled out of the same blank, this is truly a piece of art. Fit and finish are spectacular as well. Mine performed flawlessly and gave me 1.25 inch groups at 100 yards and i am sure i can do better. Having the piece of mind of a robust gas block/barrel combo while not compromising precision is a win. Definitely recommend this.
