  • Publication number: 20150075051
    Abstract: The present folding stock adapter can be used with many types of military-type assault rifles that typically comprise a receiver extension, buffer and action spring. The present folding stock adapter can be used to add a folding capability to a standard stock allowing it to fold against a rifle's receiver when the weapon is not in use, thus reducing the overall length of the weapon. This reduction in length can facilitate its maneuverability, storage and transport in cramped quarters. The present device can also allow for the quick unfolding of the stock in order to allow the weapon to function and be fire normally.

  • Patent number: 8966798
    Abstract: A recoil reducing buffer and stock adaptor having a front portion adapted to fit into and connectively engage with the backplate of an H&K-style rifle and a rear portion comprising an aperture adapted to accept and connectively engage with an AR-15/M16 buffer tube. The adaptor attaches to an H&K-style rifle between the action or receiver and the buttstock and allows the rifle to accept and function with a larger and/or stronger H&K-style rifle buffer than its original factory-installed buffer. The adaptor reduces the recoil of an H&K-style rifle by allowing the rifle to function with a larger and/or stronger H&K-style recoil buffer than its original factory-installed buffer. The adaptor also makes substantially all existing H&K-style rifles compatible with substantially all current and existing H&K-style rifle stocks and AR-style rifle stocks and stock accessories.

  • Patent number: 8955422
    Abstract: A modified bolt carrier for automatic recoil rifles and pistols preferably includes a shortened bolt carrier, a shortened buffer tube, a modified bolt key and an end cap. The shortened buffer tube is shortened by cutting-off a straight portion of a prior buffer tube. The modified bolt key includes a prior art bolt key, a rod yoke, a pair spring rods, a pair of compression springs, a spring support disc and a spring plug. The spring plug is biased outward from the shortened bolt carrier with the pair of compression springs. The modified bolt key is attached to the shortened bolt carrier and retained in upper and lower receivers of an automatic recoil rifle or pistol. The bolt spring is slipped over the spring plug and the bolt spring is retained by securing the end cap to the lower receiver with a lock pin.

  • Publication number: 20150000171
    Abstract: Threaded metal inserts for polymer lower receivers and hybrid polymer lower receivers comprising one or more of such inserts, as well as kits and methods therefor are disclosed. A threaded metal insert has a substantially circular aperture configured with screw threads to releasably yet connectively interface with a separate traditionally threaded firearm component such as a buffer tube or a pistol grip screw. Inserts can be any overall shape so long as it can be integrally embedded within a traditionally threaded portion of a polymer lower receiver in a way that does not interfere with normal operation of an assembled firearm and leaves exposed the internal threading of the insert. Inserts can also comprise textural features on the exterior surface configured to permanently interface with and embed the an insert into molded polymer.
