    Works well

    Posted by Ryan O on May 30th 2022

    Works well, it feels as if it may be brittle. I'm a little afraid of breaking it and having to spend another 15.00 on a small piece of plastic. Maybe if it was a little more inexpensive I wouldn't feel like I'm going to break it everytime I pull it out. Great idea, just feels like it may break.

    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.

    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
