    Works on some gas blocks

    Posted by Robert on Feb 23rd 2022

    Works on standard gas blocks well. However, it will NOT work on some adjustable gas blocks-such as the Superlative adjustable gas block. The gas port extends in the way of the index slot of the Gas Genie making it so you can't mark the installation position accurately.

    Made installing my gas block a cinch but I had to modify the installation procedure because of my adjustable block.

    Gas block Genie

    Posted by Gilles on Jun 28th 2021

    It is so simple to use, I was able to mark where the gas blocks should be located exactly on 2 black barrels in just minutes I used both silver and black fine Sharpies to make my intersection lines

    Simple & Easy Gas Block Install

    Posted by N. Cunningham on May 14th 2021

    Very easy way to install a new gas block. Makes lining up gas block, tube and barrel very easy and everything is lined up the way it should be. Green plastic is easy to see and clips onto barrel easily and marker wipes off for multiple uses. Makes lining up gas block & barrel very easy and probably the best way to do it at the moment.

    Must Have

    Posted by Some guy on Apr 27th 2021

    This is a must have for some styles of bolt catch the engage directly to the roll pin and not just bolt on. Cannot recommend enough!!!
