Customer Reviews
Awesome jig and lower!
I bought the Router Jig Extreme and an AR-10 Billet Lower and I am so glad I did! The jig felt super sturdy and well-made. I was a bit nervous about doing it myself, but the instructions were easy to follow. Everything just fit together perfectly when I started working on it. Took me a couple of afternoons, but the finished lower looks amazing. I even added some of their Anti-Walk Pins, and they feel solid. I'm already thinking about my next build and will definitely get more stuff from here. Highly recommend them to anyone wanting to build their own!
Consistent quality, fast shipping
I've ordered a few AR-15 80% Lowers from Modulus Arms before, and this last batch was just as good. I got the raw aluminum lowers this time, and they machined great, just like the anodized ones I got last year. Shipping was quick to Ohio, maybe 4 days. Always reliable with their product and delivery.
Jig worked out great
I finally got around to getting the Router Jig Extreme and an AR-15 Billet Lower. Shipping took about a week to get to me in Florida, which was fine. The instructions were clear enough, and I got the lower done without too much trouble. My buddy helped me out a bit, but it felt pretty straightforward. Definitely happy with how it turned out, and it was a fun weekend project.

Share tips, ask questions & help fellow shoppers save more
Hey, does Modulus Arms do a military discount? Need to pick up a few things but want to save a bit if I can.
Thinking about grabbing one of their router jigs. Are they actually better than the 5D one or should I just go with that?
