Modulus Arms

Great products! Fast shipping, with high quality milling bits and drill bits! Smoothing cutting and drilling. Great oversized shank with bearing guide for smooth cuts make for great finished work.

Awesome

Worked great to complete my 80% lower.

Perfect fit for the router I got from 5d tactical and made quick work completing the 80% lower

Jig is amazing. Extremely clean finish with speed mill. Amazing quality!
