    This was my first AR-15 build and it made the gas block alignment perfect the first try. No do and redo just straight on to a fun afternoon of shooting.

    I was told that aligning the gas block was near to impossible and while researching the method came to find this product. Order was easy, shipping was fast AND FREE and when I received it the instructions were clear and easy to follow. Whoever thought of this ingenious device needs a pat on the back for a job well done.

    saved me

    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.
