The PKT (ПК Танковый, "PK Tank") (1968) is a solenoid-fired coaxial version of PK to replace the SGMT Goryunov vehicle-mounted machine gun. Modifications include the removal of the stock, a longer (722 mm (28.4 in)) and heavier barrel that adds 30 m/s (98 ft/s) muzzle velocity, a gas regulator and an electric solenoid trigger.
The extractor moves with the bolt to pull the cartridge case rearwards out of the chamber, and at some point, the ejector eccentrically exerts a frontal push (from the case's frame of reference), which torques and "flicks" the case out of a side opening on the receiver known as the ejector port.
Most push feed mechanisms use a spring loaded plunger type of ejector situated at the breech face, and this system ejects the spent casing as soon as the case mouth clears the ejection port. [9] Most controlled feed mechanisms use a fixed mechanical ejector attached to the receiver, which results in the bolt having to be pulled all or almost ...
The Heckler & Koch G11 is a non-production prototype assault rifle developed from the late 1960s to the 1980s by Gesellschaft für Hülsenlose Gewehrsysteme (GSHG) (German for "Association for Caseless Rifle Systems"), a conglomeration of companies headed by firearm manufacturer Heckler & Koch (mechanical engineering and weapon design), Dynamit Nobel (propellant composition and projectile ...
Modified M1903 Springfield with ejection port on the left side of the receiver to accommodate a Pedersen device.30-18 Auto, also known as the 7.65mm Longue. Prior to the United States' entry into World War I, John Pedersen, a longtime employee of Remington Arms, developed the Pedersen device. His idea was to dramatically increase the firepower ...
Nembhard, who avoided ejection for the scuffle with Portis, hit 3 of 4 3-pointers en route to 15 points and nine assists. He and backup point guard T.J. McConnell combined for 17 assists with zero ...
The PDW concept has not been widely successful, partly because existing PDWs are not significantly cheaper to manufacture than carbines or full-size military rifles. Most PDWs also use a proprietary cartridge, such as the 5.7×28mm cartridge for the FN P90 or the 4.6×30mm for the H&K MP7, neither of which were originally compatible with any ...
"Full-size" variant of the MP5K, introduced in 1991. It is designed to provide the benefits of the MP5K with the size and handling of a regular MP5, and is essentially a regular MP5K with a custom folding stock, "Navy" trigger group, and 5.5-inch barrel with a custom "3-Lug" muzzle similar to that of the MP5N but for a Qual-A-Tec suppressor.
