    This was a much simpler and precise method of indexing a gas block. Wish I had found this sooner.

    If you are putting on a non pinned mil spec gas block, get one. Well worth the 14 bucks

    Works as advertised

    I needed to confirm that the gas block on my .625" journal barrels were in the correct spot. I used this cost effective tool to double check my other alignment tool. It confirmed that it was, indeed, aligned properly. Would gladly purchase again if need be.

    Worked great! Glad I purchased this & the .750 GBG at same time for 2 in progress builds. Wish I had known of these products before.

    Works extremely well, easy clean up for it's next use and should virtually last forever. Only a libtard socialist could screw this up.

    This is a good product and works well, the fact that it locates the gas port and clocks the block at the same time is a plus. The only improvement would be to make a set of many sizes for the AR Building gun shop.

    Gas Block Genie

    A great invention that makes it much easier to be sure that my gas block is correctly mounted. I've previously tried the plastic pin style alignment tool and while they work, they're a one-time use, expensive for it and you have to be sure to remove the pins after installation. This is a much better solution.
