Our take: The Airsoft Megastore Armory shotgun buttstock shell holder, constructed of durable tactical-grade nylon, is an efficient and secure way to store your spare shells and simultaneously have them readily accessible for reloads.
With three adjustable straps that basically guarantee universal fitment onto most shotgun stocks, you can use it on all the shotguns in your arsenal, as removal/adjustments are quick and easy to do. It holds up to five shell on the outside, and features a zippered storage compartment that can hold 7 more shells to ensure you have a reload ready when you're out of ammo out on the field.
In comparison to the majority of the other buttstock shotgun shell holders, the AMA Urban Assault DualStor stands out in a league of its own due to the simple fact that it has better build material, more ergonomically designed storage, and precision stitching.
