Abstract

Disclosed herein is a modular, replacement chassis stock system for an existing firearm's operating mechanism possessing a simple design and incorporating durable, commercially available components. The system comprises a chassis assembly with up to three integral mounting rails, a top rail, a replacement operating rod guide, a telescoping buttstock assembly, and a buttstock/grip mount assembly. The present invention may be used to replace the standard stock of an M-14 rifle (or copies thereof, such as the Springfield Armory M1A) such that the barrel is held in perfect alignment with up to five Mil Std 1913 pattern mounting rails. The telescoping buttstock assembly is adjustable in length via the use of a thumb lever release and includes an adjustable cheek-rest, an optionally adjustable buttpad, and a pistol grip. Auxiliary devices may be attached to the chassis stock system via the buttstock/grip mount assembly located above the pistol grip. The chassis stock system is secured at the rear of the barreled action by the installation of the trigger assembly and at the front by attaching it to the replacement operating rod guide.
