Description
The Spuhr G3 Upgrade Kit offers superior ergonomics, and is the lightest and most durable upgrade kit available for the HK G3 Battle Rifle and clones. The kit consists of an adjustable stock assembly (SKU R-410,) a modular forend (R-401,) and a Picatinny top rail (R-402).
The heart of the upgrade kit is the R-410 6-position adjustable stock, featuring a non-reciprocating cheek piece (available in four different heights) and a high heel, which allows for superior recoil absorption and faster target transition. Made from advanced polymers with an aluminum buffer tube, the R-410 also allows the retained use of the G3 standard and heavy buffers.
The R-401 modular forend features Spuhr Interfaces along the sides and bottom, allowing accessories and rail interfaces to be attached as needed. Sans accessories, the aluminium forend has the same weight as the original forend.
The R-402 top rail features a unique cummerbund design, which attaches around the front of the receiver, for a rock solid foundation for optics
