XLNT Gas Block Design
I am building a presentation AR-15 and this gas block was an exceptional value as it is functional and flawlessly designed and finished. It will make a striking addition to my build. Highly recommended for its great design and fully functional adjustment.

Installed on a 7.5 inch
Installed on a 7.5 inch barreled pistol. Installed great. Looks to be good quality and looks nice too. Have not shot with it yet. I hope it tunes well and makes the pistol run good. So far I'm happy and would recommend this.

Looks nice
Bought this for a build I'm starting next month. So I haven't used it. Looks good fits tight on barrel love that. But looking in the gas hole, it looks like the adjustment screw can't close off the gas because of the space around it. We will see next month

As advertised
Well made and tight fit

Cobratac Adjustable gas block
Gas block had a nice finish, and lightweight. Snug fit on Barrel but not too tight. Only issue I had with this block is, I was able to get bolt lock back with gas block fully closed. I was informed that the gas block was not a total shut off, but it did seem to soften the rifle shooting. I would still recommend this block due to its lightweight and softening of rifle shots.
