Very solid piece of work. The gas block installs very easily, due to the use of a screw to.the threaded gas tube retention pin that eliminates the installation awkwardness surrounding tiny gas tube roll pins! My gunsmith loved that! The gas adjustment is made with a hex allen wrench which fits an easily reached socket that has several noticeable clicks that are easy to feel while tuning your gas block. It’s a heck of a value for the price. Maybe better than many of the high-priced spreads. I have no idea why hardly any competitors go with the screw-in retention pin rather than the frustratingly difficult to install roll pin. Now if only they offered an .875 version!.

Replacing "alike" nonadjustable that has similar profile.. actually. replacing a spare adjustable gasblock that I had purchased a long while ago ( for a diff build ). It turned out to be a POS, it used Torx hardware ( not the issue ), that was so small ( the issue )on the adjustment valve that it stripped. It was still new and never used. by the time I got it out it was mangled... The new Kaw Valley product uses a bigger beefy allen key, everything moves as intended. Although my build is ready for live tests and tuning I havent been able to get away to do it...

I have pretty much standardized on this gas block. It is simple to install the gas tube with no pounding on roll pins. Plus the adjustable feature is great to have on any serious build. The quality of Kaw Valley products is second to none!! And of course Optics Planet always has a great in stock assortment that ships quickly!

It seems like good quality and I like the screw for the gas tube pin but how is the gas adjustment supposed to lock down because the adjustment screw is very loose and walks while shooting. I had to take a punch and stake it.

The best part about this is the screw that acts as a roll pin. Everything els is worthless. Doesn’t adjust gas flow at all. Literally didn’t notice a difference in the recoil or how fast or slow the bcg was moving. I would not recommend this to anyone. In fact I would like to have my money back for this disaster of a product.
Cons:
- everything else about them sucks
Best Used for:
- Staying on the shelf collecting dust
- Paper weight or staying on the shelf
Would recommend: No

The only redeeming feature is how this mates to your tube. That, is genius. Everyone else should follow their example with this screw type mating system.
That’s it. Everything else is trash!
The set screws on the bottoms don’t line up with the dimples of any barrel I tried. The gas block is extremely leaky, with carbon buildup around the base, tube opening and screw port within few rounds. Instructions are abysmal. The adjustment screw is looser than a marble rolling down a hallway and went flying after a few rounds attempting to make adjustments. I applied loctite, and it felt better, but I’ve seen better engineering /fit and finish on free Temu items
Pros:
- mating system to gas tube
Would recommend: No

Adjustment screw does not stay put, comes out completely easily and the slightest cross-thread strips it. Cheap junk, do not buy.
