  1. Excellent products 5 Star Review

    Posted by on 18th Dec 2016

    The jig is a work of art. Everything fit perfectly and made a difficult project easy. The overall quality of the jig and the lower is excellent- no improvement necessary. What a pleasure to have something be as good or even better than expected. I am building my third AR 10 (same jig)

  2. An excellent choice 5 Star Review

    Having read my information on building my own AR-308 this initial purchase of an 80% lower receiver was quickly and efficiently accomplished. I and a friend are building rifles together and will be relying on the continued support and parts provided by Modulus.

  3. If you are looking for an 80% lower... 5 Star Review

    This is a quality part. Machining and finish appear to be top quality. I have not performed the necessary machining to transform this into a functioning lower , however the dimensions overall match the drawing I have used on other 80% lowers so I don't anticipate any surprises

  4. Solid construction 5 Star Review

  5. Solid AR-10 Lower 5 Star Review

    Posted by on 10th May 2016

    The pictures don't do the machining or finish justice. Anno is a very nice deep black, and the lines are clean, minimalist, and sharp. Milled in large trigger pocket. The magazine well cuts look excellent - I don't know if they are wire EDM but they are square and clean through the full length of the well. If you are looking for a 7075 lower this is it!

    I finished three of their 7075 308 lowers with the jig and just put some rounds down range with one of them. Shot great and looks awesome.
