This tool worked perfectly for me! As someone who is new to building an AR I was amazed at how simple this was to use. Great quality and did exactly what it's supposed to do.
Does exactly what it's supposed to do; does it very well. Allows you to drill perfectly diametrically opposed to the gas port. Thanks to this tool, I found out the gas port on my barrel, not a KAK barrel, is drilled roughly 1 o'clock. just don't like the drill bit. Prefer 130 degree. 90 degrees goes too deep in the center for my peace of mind.
I don't know if the one I got missed the heat treat cycle, but it was too soft, the drill holes were a little undersized, and the provided drill bit chewed up the tool and the drill was able to wobble. Also, the HSS bit barely scratched my nitrided BA barrel. I ended up ordering a different tool from somebody else, for a lot more money, and with a solid carbide bit, Don't have it yet but have high hopes. Need to do three barrels to start.
Well made, affordable. The bit is a huge plus. I put a touch of oil before starting to drill and took care of a nitrided barrel easily. Wish I would have bought one years ago!
The jig worked great. I made sure to hide as much of the drill bit into the drill's chuck as much as possible, to prevent over drilling the hole.
Instead of going to a gunsmith, I watched a little Youtube and ordered this tool. No regrets!
It was very easy to use and did the job perfectly on my undimpled barrel.
Works great and easy to use
Jig works excellent with the supplies drill bit. I dimpled my anew value line barrel perfectly in no time at all.
