Modulus Arms

I had more fun than I thought I would. It was very easy to do the milling. Took about 1 1/2 hours for the AR-15 lower. Pins were snug and fit well. I would recommend fully enclosed eye protection. Used WD as my lubricant. Never took more than the small increments. It will be interesting to see how many uppers I will be able to do with a single bit. Took a couple weeks to ship, keep that in mind.

Arrived fast. Sharp and cuts clean. Works like it’s supposed to. Lasts longer if oil drops on cutting surfaces and given time to cool between passes. Will definitely purchase again!

Already milled two units.

This was the best choice I made, after milling with the old drill press method of milling, router jig worked much faster and cleaner.

Another great purchase on a great piece of equipment! Just love everything made from 80% Arms they are top of the line by far!
