I installed one of these on my AA 6.5 Grendel barrel and it has worked fine for me. The only thing I do not care for too much is the way it secures to the barrel: 3 set screws on the bottom. I prefer the type that clamps onto the barrel but I have had no problems with this one so I have no complaints and gave it 5 stars as such, if you don't mind the set screw type gas block this is a very functional unit that also looks nice once installed. All in all, a good buy.

Gas port drilled in the wrong place on 3 out of 5 that I ordered. Uses bigger set screws than other brands which I like. Also has 2 bottom and 1 top set screws. If they could just get the gas port position right it would be a winner.

By Brandon

Comments about J&T Distributing DoubleStar Gas Block Single Picatinny Rail AR-15, LR-308 Standard Barrel .750" Inside Diameter Aluminum Matte:

It takes a non-standard roll pin for the gas tube and I don't feel the set screws on the bottom hold it well enough. I had movement of the gas block during my first 100 rounds to the point that my AR stopped cycling. It also did not fit well on my AR when I had a 2-piece hand guard on it. Its okay for the money, but I wouldn't buy again.

A well made item, very-very tight in fit on my AR-Stoner barrel in 6.8, but that was what I was looking for anyway.

Comments about J&T Distributing DoubleStar Gas Block Single Picatinny Rail AR-15, LR-308 Standard Barrel .750" Inside Diameter Aluminum Matte:

Good solid product. Installation was quick. I really like that it has four set screws compared to other gas blocks out there with only two (namely the one I was replacing). Very solid feel. I would purchase this product again.

Comments about J&T Distributing DoubleStar Gas Block Single Picatinny Rail AR-15, LR-308 Standard Barrel .750" Inside Diameter Aluminum Matte:

This is a very good gas block, very well made, and the 4 set screws will be sure to keep it in place. The only thing I didn't like was that there aren't any specs on height so in my case it isn't perfect for mounting removable front sights unless you purchase a short riser. Lack of information is why it gets 4 stars.

Comments about J&T Distributing DoubleStar Gas Block Single Picatinny Rail AR-15, LR-308 Standard Barrel .750" Inside Diameter Aluminum Matte:

Was curious about this block, since the price is less than many... thought I had one with a misplaced gas hole but I also acquired a very high dollar block and it came with a spacer to replace the handguard cap .. which sets the block forward from the shoulder and lines the holes up perfectly. If this one had come with a spacer, it'd deserve 5 stars... it gets 4 because it forced me to think.

Comments about J&T Distributing DoubleStar Gas Block Single Picatinny Rail AR-15, LR-308 Standard Barrel .750" Inside Diameter Aluminum Matte:

The first one I got had the gas hole drilled in the wrong location. Midway immediately replaced it. The 2nd one was right on the money and works perfectly. I appreciate the 3 set screws to lock it into place. Too bad I didn't get the 2nd one first, which would have earned 5 stars.
