Abstract:
A buttstock assembly configured to work in conjunction with a compact buffer assembly consisting of a buffer tube, spring and bolt carrier with an integral buffer is provided. The buttstock assembly, buffer tube and bolt carrier are configured to work with AR15/M16 type firearms and their derivatives. By incorporating the buffer onto the bolt carrier, which is used in conjunction with a buffer tube of reduced length, the overall length of the host firearm is reduced by approximately 3.2 inches. No permanent modification need be made to the host firearm in order to utilize the compact buffer assembly and buttstock assembly disclosed herein.

Claim (Index 14):
A buttstock assembly for use with an autoloading firearm comprising:\n a housing having a longitudinally extending interior bore constructed with a front opening and a rear opening, said front opening is smaller in diameter than said interior bore, between said front opening and said interior bore there is defined an annular shoulder, said housing defining a comb about its exterior surface; a shoulder stock having a front side and back side with a opening extending therebetween, said shoulder stock has a means to slidably connect with said housing; a receiver extension which is generally cylindrical in shape defining a longitudinally extending interior bore extending between a front end of said receiver extension to an interior back end wall, defined about the exterior are at least two circumferential bands having an outer diameter that is in contact with said interior bore of said housing when coupled therewith; when said receiver extension is coupled to said housing, the forward most circumferential band bears against said annular shoulder of said housing thereby securing both said receiver extension and said housing to the autoloading firearm;
