Bought Specter Gear CQB Sling For Remington 870 with Magpul SGA Stock. The coyote color of this sling matches the color of Magpul SGA Flat Dark Eart (FDE) stock. Forward sling mount adapter included. It installs between magazine extension and magazine tube. It’s kind ironical that you can’t use Specter Gear CQB Sling For Remington 870 with Magpul SGA Stock with standard Magpul forend. Magpul Remington 870 forend is little longer and you won’t be able to slide forend forward with front sling adapter installed. So if you want to use Specter Gear CQB Sling For Remington 870, you have to choose different forend.
