Modulus Arms

Jig system is quality. It's heavy and not cheap

I love the cut and shape of these lowers. I wanted months until they were back in stock. Glad they finally did. Customer service is very quick to respond to inquiries. Pleasure to do business with.

ORDERING, SHIPPING AND QUAILITY OF PRODUCTS ARE AWESOME

Nice, product,s great quality, " price,s same. Looking tword,s buying more*

IMO, the best jig on the market! The blue copy jig I have never used. I had a black 80%er and had it laser engraved to match the SIG 516 piston upper I had. Now I have a SIG 516 clone copy. Getting replacement parts for the jig has been hassle free and the service is prompt. Hopefully The ATF will not shut down the 80% market with their decision on what is a receiver. There is language in that to shut down home building.
