Modulus Arms

Can't say enough about this lower! Machining is outstanding! Anodizing is flawless. The lines are exactly what I was hoping for to become my next and most special build!

Modulus Arms provides a tremendous jig and parts that will give years worth of service. I wouldn’t own any other, and will continue to buy parts to keep this beast going. Let Freedom ring!!!! 😏👍🏻🇺🇸

Good product and fast shipping

Well shipping the original order was very good until I had to ship the speed mill back for the right one,I had to pay for shipping to send it back and then it took over 2 weeks to get the right one, so I haven’t been able to use it yet.

Always top notch with these guys! Why settle for less buying elsewhere?
