    I was having a gas problem with my LR308 build, featuring an J&P adjustable gas block on an Aero Precision barrel. I marked and moved and adjusted, and it still would not eject properly. Literally a 5 minute fix using the Gas Block Genie ( the block seats 1/8" in front of where the barrel diameter thickens). I have three more builds slated, and having this tool in my tool box will make them a lot easier.

    Best gas block alignment tool

    This is the one of the best little tools I have bought to work on a AR when lining up the gas block it is so simple. I've had mine for over a year now I love it.

    I used this for the first time, last week. A little pricey for a plastic gadget but it worked just as it was designed. Made it easy to align the gas block on the barrel.
