Modulus Arms

very well thought out product!!

everything worked as it should great jig to work with easy to use. tooling was great a lot of thought went into this product. I have a early jig for ar15 and a separate one for a10 this even does ar 9 great product

Great product it allowed me to finish my build.

Great AR lower jig

The machine work is excellent! They had the jigs in stock and shipping was fast. Glad I picked the Modulus Arms jig over all the rest. It'll do everything I would need a jig to do!
