Most Helpful Positive Review Easiest gas block to adjust
Everyone complaining about how to adjust this block must be full potatoe.the set screw faces to the right side of the barrel so with nearly any freefloat you can get on it and adjust it. The screw at the front of the block is just a friction screw for the side screw. Fantastic design for guys runnin...

Most Helpful Negative Review Backwards - or I don't think like an engineer.
If you assemble this on a carbine or mid length gas tube system you will have to remove your handguard/rail to access the gas adjustment set screw. Really really. I thought I was seeing things at first and slapped the unit together - this block and a Spike's mid-length melonite coated tube, EZPZ -...

good little block for small handguards

by M, Verified Owner from UT, United States Written on March 31, 2025
This block was used on one of my builds. It worked nicely. I remember it took a bit to adjust the gas system, but once it was adjusted it worked great. Simple, easy, well made. Nice stuff.

Seeking Adjustable Gas Block

by Roon, Verified Owner from AZ, United States Written on January 18, 2025
Worked fine on my DPMS lr-308. Fit good but the set screws didn’t line up perfect with the dimples in the barrel. Other than that it installed easy. Tamed the recoil and it no longer smashes my brass upon ejection.
Pros:
  • Price
  • Low profile
  • Adjustable
  • comes with roll pin
Cons:
  • No adjustment clicks

cannot use with a BCM handguard

by Obabo, Verified Owner from NJ, United States Written on March 17, 2024
Got a criterion heavy barrel, .750, installed this gas block onto it, all seemed well, then I installed the handguard, and boy was it hard to get on, had to heat it up and bang it on with a mallet, but then I noticed a few minutes later that the bottom of the gas block was a hair away from hitting the bottom of the handguard, and any pressure would make them make contact, so for my precision Bill that was a no-go.

Looking into other low profile gas blocks I realized most use a 3/16" set screw, which is about 4.76mm, this seekins uses 15/64" which is about 5.95mm, so thats a 1.2mm difference , not a lot but it is enough, I can't fully blame the gas block since I hear this handguard is pretty slim.

I was thinking about grinding the bottom of it down to fit better, but then I realized when the handguard is installed, it blocks the side adjustment screw for the gas block, and for how hard this handguard is to get on and off it would not be something I would be able to adjust without an hour of work.

So for those two issues make an incompatible with my overpriced handguard I cannot recommend this.
