Overview
FAB Defense AGR870-FKSB Remington 870 M4 Shock-Absorbing Collapsible Stock
The FAB Defense AGR870-FKSB is a fixed-mount, M4-style collapsible stock system for Remington 870 12-gauge shotguns. This configuration combines an ergonomic pistol-grip adapter, adjustable M4-style stock positioning, and an integrated shock-absorbing system while retaining a fixed, non-folding connection to the shotgun.
The AGR870-FKSB is distinguished from FAB Defense's folding AGRF-series stocks by its fixed stock adapter configuration. The stock itself remains collapsible, allowing the shooter to adjust its position along the M4-style extension tube, but the assembly does not incorporate a side-folding hinge. The shock-absorbing mechanism is integrated into the stock system to manage rearward movement under recoil.
