Most Helpful Positive Review Excellent Block
Bought this gas block for my AR and was stupid easy to install. Immediately drove to the range and tested it out afterwards and everything cycled smoothly. The only hard part was installing the pin for the gas tube but with an extra set of hands it was no problem. I recommend anyone new to AR-15 building or upgrading to buy this gas block and save yourself from headaches.

Used Vltor GB2C Gas Block Clamp On/Set Screw Mount Low Profile .75 Sta...

by Surprised and Disappointed, Verified Owner from TX, United States Written on April 22, 2025
This was misleading as a "Demo". One screw is missing and threads are abused. The second screw is sheared in place having been installed from the wrong side. These clamp on gas blocks have threads on one side/half of the clamping area. The other side is thread less but has a recess for the head of the screw(s). I sure am disappointed in Optics Planet.com

Not good for me

by Z, Verified Owner from PA, United States Written on March 30, 2023
I had it on my upper and it was fine until I had to change handguards and tried to get it off. One of the bolts stripped and it was a nightmare trying to knock it loose. I ended up having to hammer it off and its no good anymore. I did not use loctite. Sucks that its useless now while being so expensive.
Pros:
  • None
Cons:
  • Bolts are very low end.
Would recommend: No

Best standard gas block

by Kenneth, from FL, United States Written on July 27, 2018
I'm running the gas block on 4 AR's at the moment. Just an overall great gas block. The only thing that I wish it was is cheaper. The best part about it is the fact that you can remove it easily without having to take set screws out that strip.

VLTOR gas block

by Elwood, from TN, United States Written on April 17, 2018

Pros:
  • easy to use
Cons:
  • None

Perfect quality.

by Tobian, from MN, United States Written on January 21, 2018
Highly recommend the clamp on version of this gas block. Much more secure than set screw. I used a nice coiled roll pin for the tube and it went together effortlessly. The fit on the barrel was very snug and there is no leaks. The gas port was perfectly spaced and nice sized. Fit and finish is excellent. Quit playin and just buy the vltor. Youll be happy i guarantee it.
Pros:
  • Perfectly machined and finished
Cons:
  • None
Best Used for:
  • Quality ar build.

Great clamp on

by Tyler Walsh, from PA, United States Written on November 17, 2017
Perfect ejection direction in my 308 build. Install was easy as heck, remember to use loctite!!!! Vltor makes an excellent product and this is no different!omly wish is that it was adjustable. It’s knife not worrying about having to dimple the barrel.

Excellent Product! Brand you can trust!

by Ohiobuckeye7, Verified Owner from OH, United States Written on July 21, 2017
I was looking for a clamp on style gas block at a decent price. Vltor is top quality. Mounted on an Anderson 7.62x39 barrel. Fit is very night and tight tolerance which means it's not going to budge. Would definitely buy another one.
Pros:
  • fit and finish excellent
Cons:
  • None
