Questions & Answers
The gas journal diameter doesn't seem to be listed anywhere. I would guess .750, but would like to know for sure before purchasing.

Yes, on the SOLGW website it states that it is a .750 gas block.

Helpful Positive Review Good Balance and Accuracy by Madison Boss, Verified Owner, October 28, 2024
Balances well with a suppressor. I installed it into a BCM upper receiver with a SOLGW BCG. With a milspec trigger and a 3x optic, I got 3 MOA groups out of the several types of ammunition. I suspect the barrel is mechanically capable of 2 MOA (or be...

Helpful Positive Review excellent barrels for an AR-Pistol build. by Kevin Margulies, Verified Owner, September 21, 2024

Most Recent Reviews SOLGW for life by Thomas J, Verified Owner, April 9, 2025
Picked up this barrel for my new "Apocalypse Rifle" build. If you're looking for something lightweight, then this isn't the barrel for you, as this 14.5" weighs almost as much as a 16" government profile barrel. However, the weight is shifted to the ...

Most Recent Reviews Spend the coin and get a Criterion Core by DAMOND, Verified Owner, March 30, 2025
Zeroing at 50yds with factory ball such as PMC Bronze, PSA 5.56, and Hornady FMJ. I was only able to get 4" horizontal groups. While my Core 13.9" build with same ammo was getting keyhole. I can't imagine what the group will look like at 100.

Product Info for Sons of Liberty Gun Works 5.56mm Combat V2 Threaded Barrel

The SOLGW V2 profile was designed with our customers’ needs in mind, delivering increased accuracy while balancing suppressed handling and performance.image

With the significantly increased chamber support, our V2 contour barrels are better suited for modern configurations where lights, lasers and suppressors all add to a commonly muzzle heavy carbine.

The transfer of material to the rear of the barrel helps to offset the weight of accessories, and stiffens the barrel at the same time - reducing POI shifts between suppressed and unsuppressed use. The gas journal length has been shortened as well to optimize weight distribution, so please note that fixed front sight bases will not fit on this barrel, only low profile gas blocks.

Our V2 barrels remain appropriately gassed for use with or without a suppressor of your choosing
