DEFINITION

Classification: 89/165

(under subclass 162) Guns, usually termed "long recoil guns", wherein the barrel and breech block recoil substantially the same distance, and the fired shell is extracted by the subsequent counter recoil (forward) movement of the barrel relative to the breech block.

(1) Note. The breech block (or an auxiliary cartridge fed slide) is usually held in recoil position during extraction by a catch which is automatically released after extraction is completed.

(2) Note. So called "short recoil" guns are distributed

among the various subclasses indented under subclass 162, particularly subclasses 171 through 176.

SEE OR SEARCH THIS CLASS, SUBCLASS:

163, 169 through 176, for "short recoil" guns, i.e., those in which the barrel recoils are relatively short distance locked to the breech block, and then the breech block is unlocked and continues to recoil, extracting the fired shell.
