Modulus Arms

The best

Great customer service, parts were in stock an shipped quickly. Always have first class treatment, thanks!

Jig works great with any lower I’ve tried.

Found exactly what I was looking for, ordering was easy and it arrived fast. It was everything it was advertised to be and was easier to set up and use than I thought it would be. Made my first attempt at an 80% lower turn out like I was a pro!

The tooling was as advertised
