I think this is a fantastic upgrade for the Remington 870. It may look funny, but the grip is comfortable, and the polymer is extremely tough. In addition, the SGA is extremely comfortable, with a lot of adjustment available to the shooter.
The SGA Stock is an ambidextrous, user-configurable buttstock designed to add much-needed adjustability to the tried and true Remington 870 12ga shotgun. Featuring a spacer system for length of pull adjustment, improved grip ergonomics, recoil-reducing butt-pad, optional cheek risers for use with optics/raised sights, and other accessories, the SGA 870 brings Magpul design and engineering to another classic American firearm.
