NEW Hunters EDGE Ultralight.
We created this new ultralight hunting stock using the technology we developed for the very popular EDGE benchrest stock. It is a slim classic style and may be inletted for any right or left hand Remington 700 or Model 7, Savage, Winchester Model 70 or Montana 1999 bolt actions in most bottom metal configurations. The slender forend will accept up to a factory magnum barrel contour or custom barrel similar to a #3 Douglas or smaller. This all-graphite stock comes standard with aluminum pillars, a 1/2" Pachmayr Decelerator recoil pad and two sling studs in any of our painted colors. The finished stock will weigh in at 21-23 ounces, depending on the action cutout. It is not available in molded-in camo or marble finishes in order to save weight. Though an ultralight, it is still guaranteed to handle the recoil of all magnum cartridges thru .338 caliber.
That sounds very light for a finished stock.
