‘Father of the PDW’ Passes: Mack Gwinn Jr, Dies at 79

Florida-born Mack W. Gwinn, Jr., the son of a retired Army officer, joined the U.S. Army Special Forces in 1961 and served until 1972, a period that included seven deployments to Vietnam, earning several Purple Hearts and the Bronze Star in the process.

Then, on return stateside following the war, he developed the Bushmaster Arm Pistol. The concept, a pistol-sized gas piston firearm that used an intermediate round rather than a pistol caliber, could rightly be described as one of the first personal defense weapons and predated the initial crop of large format AR handguns such as the OA-93 by a generation.

Moving on from Bushmaster, Gwinn went on to take out several patents on magazines as well as design and develop concepts for numerous other firearms applications including the SSP-86 pistol (see the Magnum Research Lone Eagle), developed the QCB system that FN used for the modern M2HB/M3 .50 cal, and lots of other neat stuff.

Capt. Mack W. Gwinn, Jr. (U.S. Army, Ret.), 79, died on March 11, 2024, at the Maine Veterans’ Hospital in Togus.

End of a black rifle era

Back in the early 1970s, there was really nobody in what is now known as the “black rifle” space other than Colt with its R6000 series rifles and carbines (the now extremely collectible “SP-1” AR-15 with no forward assist) and the hard-to-find (and often out of production) Armalite AR-180. Every now and then, an importer would bring over a few FALs, Valmets, or HKs, but that was it.

Sure, you could get a wood-stocked M1 carbine, a couple of different semi-auto M14 variants, or the Ruger Mini-14, but if you wanted an AR, you basically had to call Colt.

Then came Capt. Mack Gwinn, who started what was first Gwinn Firearms, located in Winston-Salem, NC, and then Quality Parts, and finally Bushmaster, after the name of their first marketable firearm, the AR-ish Bushmaster “Armpistol.”

Bushmaster Armpistol ads started popping up in the early-1970s

The company also marketed what was called the “Bushmaster Assault Rifle” for a time, with a pedigree that was very Stoner while steering clear of Colt’s patents

After Gwinn left the company, Bushmaster eventually began making legit Stoner/Sullivan-style AR clones in the early 1980s, along with Olympic Arms, which were basically the first two non-Colt names in that space.

Under Richard Dyke, the company moved to Windham, Maine, and kept at it until 2006, when he sold the firm to a holding company that eventually became the terribly-run Remington Outdoors. Fast forward to 2011 and “Big Green” had made the decision to move the concern “lock, stock, and barrel” out of Maine to its factory in Ilion, New York, leaving behind many of the old workers and the factory in Windham.

Dyke, only days out of his non-compete agreement, rebooted the old Windam factory (which he had the title to) as Windam Weaponry staffed it with experienced former Bushmaster employees looking for jobs, and just three months later was in production, making WW-branded ARs.

Windham Weaponry did a great job with “retro” builds such as these 20-inch A1s

This kept on trucking for 12 years, until Dyke passed away in March. Now, Windam says everything has basically gone south and the company has closed its doors, headed for “a full liquidation which should happen within the next month or so.”

Of course, Bushmaster has since died out and then been rebooted in Carson City, Nevada as a subsidiary of Franklin Armory, but, with AR production ending in Windam after 30 years, it just seems like the end of an era.

Plus, it leaves Maine without a major gunmaker for the first time in a very long time. The state had 21 other Type 7 FFLs – firearm manufacturers – on record in 2021, the most recent figures available, but none produced more than 100 guns, and most made under a dozen guns.
