Perfect little tool

This is so simple, yet super effective at getting the gas block on perfectly aligned every time. I like that it's reuseable since I do so many AR builds. Would definitely recommend even if using only one time.

Simple but it works.

A handy item for quick gas block alignment, can be reused over and over. Works good.

East As Pie

Used this on a recent build with an M4 barrel where gas block - gas port alignment usually allows for a plate between the gas block and barrel shoulder. So, it can be a little tricky without some kind of alignment help. This tool is intuitive and makes aligning the gas block pretty easy.

Great gift

Don't really know about using product as I bought for gifts. Directions made use look easy.

Should Be In Every Toolbox

This is a stupid simple tool that works very well. In the process of revamping a couple of ARs, the Gas Block Genie proved it's worth when I found one the rifles was set up wrong with a portion of the gas hole covered by the block itself. The Genie fixed that by providing for the correct alignment. This is so easy to use and accurate.

It's simple but it works.

Used this on my AR with a 0.750" gas journal. Pretty easy to use and cheap.
