The recoil system can either be integral with the barrel or the carriage. Some guns designed before recoil mechanisms became integrated on the gun carriage could be attached to an external shock absorber which was a spring/rubber tether that attached to an eyelet on the base of the gun carriage and was attached to a ground anchor at the other end.
A disassembled Mauser action showing a partially disassembled receiver and bolt. In firearms terminology and law, the firearm frame or receiver is the part of a firearm which integrates other components by providing housing for internal action components such as the hammer, bolt or breechblock, firing pin and extractor, and has threaded interfaces for externally attaching ("receiving ...
The usual recoil system in modern quick-firing guns is the hydro-pneumatic recoil system. In this system, the barrel is mounted on rails on which it can recoil to the rear, and the recoil is taken up by a cylinder which is similar in operation to an automotive gas-charged shock absorber, and is commonly visible as a cylinder mounted parallel to ...

The cooling jacket for all those designs also acted as the frame within which the barrel recoiled on firing, and which the fixed portion of the muzzle booster was mounted on. In 1915 an air-cooled version was created for use as a fixed aircraft gun, designated the lMG 08 (or LMG 08, traditionally with a lower case "L"). Eliminating water ...
Since the spring can only be compressed a certain amount, this limits the amount of force the spring can absorb, and provides an inherent level of self-regulation to the action, allowing a wide range of shotshells to be used, from standard to magnum loads, as long as they provide the minimum recoil level to compress the spring. Note that the ...

The original idea was based on the Knight's Armament Company Masterkey system, which dates back to the 1980s and originally comprised a shortened, tube-fed Remington 870 shotgun mounted under an M16 rifle or M4 carbine. The M26-MASS improved upon the original Masterkey concept with a detachable magazine option and more comfortable handling ...
