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.

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.
