Most Helpful Positive Review Light Weight Budget Gas Block
This is a no frills gas block that is probably lighter than many of the "lightweight" gas blocks I've seen due to the thin sidewalls. The finish is not as good as other gas blocks that I have used, but it does the job at a low price.
Most Helpful Negative Review Bad Gas Block
It is one star because the program will not let me select no stars. This gas block is non functional. The quality is poor and no quality checks must have been made on this item during manufacturing.

Basic Gas Block

by Ryan, Verified Owner from CO, United States Written on February 9, 2019
It is your basic gas block. Inexpensive and easy enough to install. The finish is what you should suspect in the picture. I used this gas block for a 300 blackout pistol and it runs super sonic rounds fine. Wouldn't recommend it for shoot subsonic rounds but, other rifles and pistols it should be fine.
Pros:
  • good value
  • Inexpensive
Cons:
  • None
Best Used for:
  • Most AR platforms.
Would recommend: Yes

Great look for that new stainless barrel

by D8, Verified Owner from MO, United States Written on April 18, 2017

Pros:
  • Good fit
  • highly polished
Cons:
  • None

.625 Gas Block!

by Johnny Shelton, Verified Owner from VA, United States Written on November 14, 2016
The Gas Block was well made and comes with three Hex Head Screws! Fit right on my Barrel and worked very well cause I used a Slim Line 13" Floating Hand Guard! Thank you for your fast service! I will use this Gas Block again when I buy a 20" barrel! It's steel but lighter than the Standard site!

Great Gas Block

by wrath04, Verified Owner from WA, United States Written on October 12, 2016
This was easy to install on my AR15 build, and the price is hard to beat for such a quality block.

The 3 set screws made this block rock-solid and it even came with the gas tube roll pin, I always dimple my barrel just to ensure my block is not going anywhere, great block, would buy again!
Pros:
  • None
Cons:
  • none so far
Would recommend: Yes
