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.
Claims19
A buttstock assembly for use with a gas operated firearm comprising:
- shoulder stock;
- two guide rods with notches;
- a housing comprising an exterior and an interior with said interior defining a longitudinally extending circular bore sized to receive a buffer tube comprising circumferential ridges that contact an interior of said longitudinally extending circular bore;
- said housing having a forward face comprising a protrusion to engage an opening on a lower receiver of said gas operated firearm;
- said housing defining three openings, wherein one of said three openings is sized to allow passage of a threaded portion of a buffer tube and said one of said three openings is smaller in diameter than said longitudinally extending circular bore thereby creating an internal shoulder between said opening and said longitudinally extending circular bore, wherein said internal shoulder rests against a forward face of one of said circumferential ridges, and wherein two of said three openings are smaller openings to receive and support a portion of a guide rod;
- wherein said shoulder stock is mated with said two guide rods, which are mated with said housing to form a portion of said buttstock assembly;
- and
- a bolt carrier having a front end and a back end as said bolt carrier is positioned in a receiver of the autoloading firearm, said back end defining an enclosed longitudinally extending bore, a buffer having a generally cylindrical shaped front end and rear end with a connecting member extending there between, said front end and said rear end of said buffer are larger in diameter than said connecting member, said connecting member of said buffer is housed within said enclosed longitudinally extending bore of said bolt carrier, said rear end of said buffer protrudes from said back end of said bolt carrier.
