  1. PB

    My 223 & 308 iigs worked perfect for completing multiple lowers.
    A PERFRCT FIT, tight and snug.
    I couldn’t be happier with the results.
    Maybe prior reviewer had a sloppy non-mildpec lower?

  2. Sammy B

    The jig kit was everything I expected. It fit tightly around the 80% lower and protected it from my bench vice.
    Instructions were so easy to follow even my 16 yr old grandson was able to mill a lower (under adult supervision).
    I could not be more pleased with the quality – good for multiple builds.

    I found this jig kit to be to basic for the level of intricate machining necessary. Picked up the right 1 on

    It’s a good jig if you have a drill press or cnc mill but if you are planning to use a router you can’t. I’d say that’s the only down fall. What I did was used this to drill the 5/8 holes then put the lower into a 80% arms jig to router the rest. Let me tell you those 5/8 drilled holes make milling go by a lot fast probably 40 minute it took me to finish. Thanks again thunder tactical!
