Most Helpful Positive Review Works Great
I installed this on my 4th AR build. The package was missing a set screw, no big deal, I stopped at the hardware store and bought one for about 20 cents. It went on a 7.62X39 "AR-47" and the rifle shoots flawlessly. My iron sights mounted at the proper level and lined up great.
Most Helpful Negative Review Stripped screws.
Two of the screws stripped with almost no resistance. Could not torque it to the barrel. Luckily I had extra screws that were slightly larger and was able to tighten it to the barrel. One of the back slots was badly stripped that I could only screw in 3 of the 4 slots.

Raised Gas Block

by ZombieJeep, from MO, United States Written on May 31, 2022
Been looking for a raised gas block for a while and found this one on this website. It was easy to install, no slipping so far with about 200 hundred rounds. Works great for a great price. I would recommend this to anyone.

Slim Fitting

by MaDeuce, Verified Owner from MN, United States Written on October 1, 2021
Easy to install and enough clearance for FF handguards on my carbine. Looks great. Just what I needed to still use gas block mounted sights and extended carbine handguards. Couldn't be happier. The only down is that it did not come with a spacer for FFHG.
Pros:
  • Fitment, installation
Cons:
  • No delta ring replacement spacer
Best Used for:
  • Carbine with extended FF handguards
Would recommend: Yes

My 2nd one

by Stupid Moose, Verified Owner from WA, United States Written on July 30, 2021
Quality better than expected, solid 4 set screws, on line with front float handgaurd. No slop, tight tolerances. Would recommend over others I've tried, that looked quality, just to find loose I.D. tolerance and rail tolerance.
Pros:
  • Perfect for those wanting to mount front sight on barrel with free float handgaurd.
Cons:
  • ?
Best Used for:
  • 15/10 platforms
Would recommend: Yes

I really love the design of this gas block.
Its tightened on to the barrel with 4 screws on the bottom, it comes with a pin for you to hammer it down on your barrel with the gas tube.
It does not however come with the allen key for the screws.
Pros:
  • cool design
  • Cheap / good quality
Cons:
  • no allen key
Would recommend: Yes

Double star gas block

by BH, from VA, United States Written on March 15, 2020
Fits good and has 4 sets screws to hold in place. Allows for your front sight to actually be at the same height as the rear so that’s nice. Only complaint is that the finish looks kinda cheap, has a slight gray chalky look. It does the job and price is right.
Pros:
  • fits
Cons:
  • Finish
Would recommend: Yes
