John P. Foote is an American inventor and former firearms designer. He worked at Military Armament Corporation during the 1970's and designed a numerous amount of submachine guns and assault rifles.


Foote was born on the 23rd of August, 1937 in Lovell, Wyoming. Since his teenage years, Foote had a keen interest in firearms and built his first rifle at age 14. After graduating from the University of Texas with a degree in mechanical engineering in 1962, Foote got a job working as a test engineer for SR-71 Blackbird aircraft at Pratt and Whitney.

Later Foote got a job at AVCO Ordnance and developed rocket-powered firearms similar to the Gyrojet pistol, but details surrounding Foote's designs during this time are scarce. One of his weapons was a 40mm shoulder-fired weapon with a drum magazine and another was a 16mm handgun.

In 1966 he joined TRW and met Eugene Stoner and worked with him on a 25mm Bushmaster gun, as well as other designs. He briefly left TRW to work with Colt on a successor to the M16 series of rifles, but he soon rejoined TRW and worked there with Stoner until the plant closed in 1970, after which he worked at Military Armament Corporation with Gordon B. Ingram and Maxwell G. Atchisson, both of whom he became good friends with. At MAC, he invented a rifle called the FAC-70 (Foote Automatic Carbine) and attempted to strike a deal with Sterling Armaments Corporation in England to manufacture his rifle, but nothing became of this, despite Sterling showing great interest in the weapon. Shortly afterwards, MAC experienced financial problems and was forced to close.

After MAC closed, Foote set up the U.S. Armament Corporation. Here, he invented a .22 conversion for the M16 rifle, which was adopted by the US Army as the M261. He also tried again to strike a deal with Sterling for his FAC-70 rifle, but Sterling demanded production blueprints, which Foote could not provide since his rifles were all hand-made. He did, however, collaborate with Sterling to produce the Foote-Sterling pistol, which was a downscaled semi-automatic .22 version of the Sterling L2A3. Only about a hundred were made.

Later in his life, Foote set up the J.P. Foote Company, which did not produce firearms.

Foote, 81 years old as of 2018, is retired and enjoys spending time with his children and grandchildren. He is very active and helps out part time at Ready Hardware and U-Haul at Shallowford in Marietta, Georgia.
