CROSS-REFERENCE TO RELATED APPLICATION
This application is a Continuation-in-Part of pending application Ser. No. 09/239,274, now U.S. Pat. No. 6,256,921 filed Jan. 29, 1999.
A stock connector allows for secure attachment of various stocks to firearm receivers. The stocks can be changed out easily and quickly in the field, without the use of specialized tools.
A gunstock incorporating one or more storage magazines for temporarily storing and retaining ammunition for easy access, the ammunition having a generally flat or recessed nose such as found for example in shotgun shells. The magazine has a port allowing insertion and removal of the shell and a biasing means whereby a single or multiple shells is pushed forward such that the recessed nose abuts against a projection member. The junction between the magazine bore and the magazine port is configured as a cornered edge on the interior side, and the distance from the cornered edge to the projection member is determined as a function of the ammunition to be stored, such that with a shell disposed against the projection member, the cornered edge will be located at least halfway up the annular brass base of the shell. In addition, the gunstock is provided with a pistol grip, which provides an improved means for grasping and holding the weapon while ammunition is being removed and loaded.
A gun barrel handguard includes half sections having longitudinally spaced apart fins of plastic material positioned around the exterior of the gun barrel for absorbing heat but preventing it from being quickly transmitted to the exterior of the handguard.
