The present invention is a modular gunstock utilizing a two-piece mounting structure and a stock module. The structure comprises a weapon attachment, in the case of an AR15/M16 rifle a receiver extension tube, and a sleeve slidable over said attachment and containing mounting structure for the stock module. The disclosed stock module is adjustable for length and features a length pre-set system, a latch with independent dual-pawls and an integrated impact buffer, modular tailpiece, and storage. The sleeve also features a position selectable fixed cheek plate.

What is claimed is: 1. A modular gunstock comprising: a. a weapon interface structure having a cylindrical profile; b. a sleeve module slideable upon the cylindrical profile, the sleeve module further comprising interface structure for a stock body; c. structure to fixedly interface the sleeve module and the interface structure; d. an adjustable for length stock body with a latching mechanism, the latching mechanism further comprising two independently operated pawls designed to interface with the interface structure for the stock body. 2. The modular gunstock of claim 1, the weapon interface structure being a receiver extension tube. 3. The modular gunstock of claim 2, the structure to fixedly interface the sleeve module and the interface structure being a bolt secured end cap keyed into structure on the sleeve and being secured to the interface structure. 4. The modular gunstock of claim 1, the interface structure for the stock body being a rail, located on the lower half of the sleeve module. 5. The modular gunstock of claim 1, the latch further comprising an impact buffer. 6. The modular stock of claim 1, the stock body further comprising a selectable and replaceable tailpiece. 7. The modular stock of claim 1, the sleeve module further comprising a cheek plate removable from said sleeve module and positionable in one of a plurality available selectable positions relative the sleeve module. 8. A modular gunstock comprising: a. a weapon interface structure having a cylindrical profile; b. a sleeve module slideable upon the cylindrical profile, the sleeve module further comprising interface structure for a stock body; c. structure to fixedly interface the sleeve module and the interface structure; d. an adjustable for length stock body with a latching mechanism; and e. a length of pull pre-set system, the system comprising a plurality of threaded holes located on an underside of the sleeve module, a stop bolt capable of threadingly interfacing with any of the holes, a spring biased lateral latch with an upwards angular block located on an upper side of the stock body and positioned such that the angular block will strike the stop bolt if the stock body is extended relative to the sleeve module to a point determined by the location of the stop bolt and the latch is in a neutral position, and may be extended beyond said point of the latch is biased so the angular block avoids the stop bolt.
