FAB Defense Collapsible M4 Stock Features The FAB Defense Collapsible M4 Stock brings an adjustable M4-style stock platform to the Remington 870 12 gauge shotgun letting shooters change length of pull to match their body type or the gear they are wearing. Constructed from durable polymer the stock is built to handle the recoil of repeated 12 gauge use without cracking or loosening over time. The collapsible design allows for quick tool-free adjustment between multiple length of pull settings which is especially useful when switching between standard clothing and bulkier cold-weather or tactical gear. This adjustability makes the shotgun more versatile across a range of users and shooting conditions. The kit includes a pistol grip replacing the traditional straight stock grip with a more ergonomic vertical grip angle that many shooters find improves control during recoil. This modernized control layout can make a significant difference in follow-up shot speed and overall handling particularly in home defense or tactical applications. Finished in Black the stock and grip combination gives the 870 a cohesive purposeful look that matches other tactical accessories. The FAB Defense Collapsible M4 Stock is for sale at GrabAGun for Remington 870 owners who want to modernize their shotgun s ergonomics and adjustability.
