The AKITA adjustable hunting stock with forend from ATI is designed to fit 12 & 20 gauge shotguns from Mossberg (*500/535/590/835); Winchester (1200 & 1300) and Remington (870) using the included adapters. The length of pull can be adjusted to 4 different lengths from 12 3/8" to 14 3/8" with the push of a button and the cheek rest is adjustable up to 1/2" to further customize the fit. The included Scorpion Recoil Pad absorbs the energy wave from high powered shotshell loads. Camouflage and wood grain patterns are injected into the DuPont Extreme Temperature Glass Reinforced Polymer stock using the DyeHard process that makes them impervious to solvents, oils and insect repellants. All adapters and bolts for all 3 guns are included. *Forends on the Maverick 88 and the new Mossberg 500A, B & C cannot be replaced because the action bars are attached to the forend.
