Hi All,
I bought this jig several years ago and never used it. So, this past week I break it out, find the instructions on the web and start working on a 80% lower (one with the rear shelf already milled out if that makes a difference). The drilling goes well but as soon as I set up for the router things get a little wonky. I set up the depth using their jig for the first pass and the bit doesn't even touch the metal ! From what I can find on the web (there's a great write-up on ar15.com, and I put this same question there as well) it looks like the tip of the end mill should have been at least a 1/16, or even an 8th, inch below the top of the lower.
So far Modulus has not answered my emails and it appears they went out of business briefly in/around 2017 and may be owned by 80% Arms ?
Anyway, does anyone have any thoughts about what could be wrong ? Should I just finish milling to the max depth of the jig as per instructions and see if everything fits ?
Is my lower already toast ?
Thanks for any help,
Peter
