Most Helpful Positive Review M4/AR15 Low Profile Gas Block
I decide to change the fore end on my AR and go to a Free Float hand guard. Mostly I want to get rid of the front sight which cause a ghost image in the scope. I knew how to do this job, but I had not actually done it before. You will need the proper size punch to remove the old sight. Once this is done it is fairly straight forward. The block fit the barrel perfectly. It came with a new pin for the end of the Gas tube. There are two Allen Set Screws on the lower side to hold unit in place.

Great quality, good price, and fast shipping. A must have for your trinity force atlas free float Hand guard. This product was shown with white Trinity force logo on the side but when I received mine it was all black without the white lettering

Great budget buy or bulk buy

by Robert, Verified Owner from FL, United States Written on June 30, 2018
If you need a couple of gas blocks, or you are trying to keep cost to a minimum. This gas block meets all the requirements. I bought this for one of my AR's that I wanted a free floating barrel (found a low cost one also), but didn't want to pay for an over priced low profile gas block that you see at so many stores(online or otherwise). Good quality material, and it works like it should. I have and will continue to recommend this gas block to anyone that needs to cut costs or buy a number of them.
Pros:
  • cost
  • great quality
Cons:
  • can't think of any
Best Used for:
  • Budget or bulk buying.

by Jon Zauner, Verified Owner from MI, United States Written on April 20, 2017
This is a great replacement gas block for your custom build. Worked especially well for free float hand guard, plenty of clearance inside the guard. It was and easy installation and a great fit on my Anderson upper assembly.
