Stoner SR-50 (Stoner Rifle-50)

History

In the early 1990s, the US Navy abandoned the bolt-action rifle. 50 BMG rifle and want to go back to their original requirement for a semi-automatic rifle. 50 BMG rifle.

Given the success of the USMC with the Barrett M82, a number of companies decided to develop their own semi-automatic. Including the 50 caliber rifle, Knight Manufacturing Company (now known as Knight Arms). Eugene Stoner, the designer of the AR-15 and SR-25, and later a KMC employee, began developing semi-automatic ones.

1996 50 caliber rifle designed to complement the SR-25. The rifle was designed for a short period of time, about a month; a working prototype was also produced for internal testing at KAC's old facility in Vero Beach, Florida.

The rifle was advertised on billboards, and people who wanted one paid a $1,000 deposit.

At the same time, however, KMC has doubled the manufacturing capacity of the Mk 11 series. This is a case of poor timing when the Clinton ban went into effect. As a result, KMC invested all of its funds in the expansion to meet its military contracts and perform commissioned work for Colt.

Eventually, KMC received an order to build mufflers for the MK23 and the entire Heckler & Koch product line, and the SR-50 project was put on hold for a short time.

The first prototype was called too light, although it worked well after some modifications to its magazine. Some kinks were also found in the second model, which is believed to be ready for mass production.

While KMC was producing some parts for a small test series rifle, it was later discovered that there was a problem with the bolts, causing service to be suspended.

Unfortunately, before this was all done, Stoner died of brain cancer and essentially stopped developing; the weapon was later handed over to "an incompetent designer" who was said to have worked so hard on the design changes, so much so that a complete overhaul was required to approach the reliability of the previous prototype.

Some engineers at KMC attempted to restore the project to its starting state by designing another improved version of the rifle; parts were also fabricated to test and evaluate this improved design.

Ultimately, KMC decided not to pursue the matter, as the military didn't seem to have any real interest in autoloading. 50 caliber rifles other than the Barrett M82, with a focus on SR-25 production.

KAC appears to have refunded everyone who ordered the SR-50 "without losing their place in the queue".

Only four rifles were made, three of which survive today; Rifle No. 1 is in the Modern Arms Hall of the Military Technical Academy; No. 3 and No. 4 are believed to be still in KAC, while No. 2 was removed "for incompetence" destroy.

The history of this rifle is considered by KAC employees as "the most wonderful pain point".
