About Precision Machined Parts


“Precision Machined Parts is committed to satisfying  customer requirements

and to the continual improvement of building guns and their parts to meet those needs.”

Beginning in 1979 with one Bridgeport mill and an engine lathe, Precision Machined Parts (PMP) has evolved into a dedicated facility to concentrate on creating precision gun parts and builds.  We provide high quality components for firearms. PMP has established it’s reputation by supplying customers with both precision machined and hand honed parts they are proud to call their own using the Precision Machined Parts, Inc. design and patented adjustable Barrel Nut for unsurpassed accuracy.

Today, we occupy a clean, 2,100 square foot climate controlled complex in Nevada, Missouri.

A family-owned business, PMP was established by Martin Hill. Hill received his early training at Pittsburg State University and later worked with Martin Marietta and several smaller machine shops before starting his own company. PMP was incorporated in 1992 with Jenet Hill as President and owner and Martin Hill as General Manager.
