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.
