Masterpiece Arms

A Georgia machine shop that opened its doors in 1973 spent its early years on general contract work, nothing related to firearms. That changed once the ATF began treating certain open-bolt semi-automatic designs as unregistered machine guns under federal law. The shop's owner set about re-engineering the MAC-10, the compact submachine gun Gordon Ingram had designed a few years earlier for the short-lived Military Armament Corporation, into a closed-bolt configuration civilians could legally own. The redesign worked, and it became the shop's first real firearms product.

That shop became MasterPiece Arms under Gary Poole, and by the company's own account, the brand dates to 2000. Poole built out a line of semi-automatic MAC-10 and MAC-11 pattern pistols under the MPA30 and MPA10 designations, along with the compact Defender series, on a design that had never found favor with the military or police it was originally pitched to (the U.S. Army passed on the MAC-10 for the Beretta M9 decades earlier) but had built a durable following among civilian shooters and a long list of film and television cameos.

In August 2008, Phil Cashin, a CNC machinist who had spent his career in precision metalworking, bought the company from Poole. Cashin kept the MAC-based Defender line running and pushed the shop toward tighter tolerances and a more industrial footprint, moving toward ISO-certified production and expanding well past forty CNC machines. He also tried a design outside the MAC platform: the Protector, a compact .380/. The 32 ACP pocket pistol drawing on the SeeCamp layout arrived under his ownership and stayed in the catalog for only a few years before it was discontinued.

The turn that defined the modern company came in 2014, when MPA designed its first bolt-action rifle chassis, entering a precision rifle market in which it had no history. The MPA-308 BA rifle built around that chassis earned an Editor's Choice award from The Truth About Guns the following year, and the chassis line kept expanding from there: the BA Competition Chassis, the Enhanced Sniper Rifle Chassis, and, in the fall of 2019, the Matrix, built around more than a hundred combinations of grip, thumb rest, and trigger-finger support. By 2017, MPA had been named the Precision Rifle Series' official chassis, a distinction it held across consecutive seasons, and independent tracking of top PRS finishers has since put MPA chassis in the hands of roughly a quarter to a third of the field in most years.

MPA carried the same competition logic into handguns with its DS series of double-stack 1911s, introduced around 2020 and built for USPSA, IDPA, and 3-gun use, followed by the Matrix Professional chassis in 2022 and continued DS9 variants. Production now runs out of facilities in Comer, Georgia, with more than forty CNC machines and a workforce in the range of forty to fifty people; most parts are machined in-house rather than outsourced.

For a collector, MPA sits in an unusual position: it makes both a piece of American gun-culture ephemera, the MAC-10 clone that has shown up in decades of action films, and a modern chassis platform that professional PRS shooters actually compete with. Few manufacturers span both ends of that range, from open-bolt-era novelty to a chassis system that keeps landing on national podiums.
