The Magpul SGA Shotgun stock is an aftermarket stock available for the Remington 870 and (separately) the Mossberg 500/590/590A1. It features:
- An ergonomic grip
- An adjustable spacer system that give flexibility on length of pull (12.5″ – 14.5″)
- A decently squishy buttpad
- Built in 1.25″ sling loops on both sides
For accessories, there’s a cheek riser and a butt-pad adapter that lets you use Remington 870-compatible butt-pads instead of whatever pattern Magpul used.
