Modulus Arms

It is my first time and this jig is easy to use and the result is a professional milling job!

Great service. Package showed up on time and my order did exactly what it said it would do. Will be ordering again from them.

So happy after purchasing several jigs that did not work this one did! Modulas arms did it right, fits all my custom lowers Good instructions quality parts great all around. Thank you for thinking outside the milspec box.

A+

So far work just as it should.
