Abstract: A modular gun stock includes a forestock supporting the action and barrel, and a buttstock assembly removably secured to the forestock. The length of the buttstock assembly is selected to provide a desired length of pull, such that replacement of the buttstock assembly provides ready customization of the length of the stock for different shooters, or for different shooting situations. The buttstock assembly includes two projecting locating pins that are received in complementary bores defined in the forestock. A rubber insert, located in the tip of each locating pin, and a gasket disposed between the buttstock assembly and the forestock, are respectively slightly compressed as the buttstock assembly is secured by a threaded fastener to the forestock. The durometer of the rubber insert and material of the gasket are preferably selected to lessen felt recoil and damp vibration.
