    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

    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.

    This is a great tool to have even if you have a dimple jig. It allows you to cross reference placement and gives you peace of mind.
