Most Helpful Positive Review Pin-on is the way to go.
This gas block is one of the few that has the ability to be pinned. You can screw gas blocks down all you want, but there is always the chance it will move. Once it is pinned, it isn’t moving. Yes it will cost you an extra $50 or so to have your barrel drilled and pinned by a professional, but it is money well spent and once done you will never need to give it a second thought. Great Geiselle quality, low profile so it fits under all the various floating handguards I have. Buy it, pin it, and you won’t regret it.

Geissele Automatics does not disappoint! Can’t say enough great feedback about their superior craftsmanship and reliability quality! The material they chose for this gas block is one of the finest! I was sold at bombproof!

always good quality.

The roll pin doesn't line up with a2 taper pin slots. I should've taken a bit more time to read and understand the caption. I still kept and used the gas block (i have the equipment). Its definitely made to be "bomb proof".

Grissele super gas block

by Larry, Verified Owner from MO, United States Written on February 26, 2024
This is my third geissele gas block that I've purchased and they have all been great. I've pinned one and the other two I used the set screws only. After thousands of rounds they are all still going strong.
Pros:
  • Very reliable
Cons:
  • None

Best military grade gas block

by Paul, Verified Owner from FL, United States Written on November 29, 2023
You cannot go wrong with Geissele products, cause they are very designed, durable and made of quality material. In addition, stainless steel gas blocks have prolonged life compared to others due to corrosion resistant properties of stainless steel. Finally, the Geissele gas block can be pinned to avoid rotation which is critical to a proper function of a weapon. On a barrel it seats tightly as it supposed to and fit nicely under any handguard. I would definitely consider buying it again.
