Like many people I found the Spectrum's stock foregrip to be small, wobbly, and uncomfortable in either position but without it there's not a good place to hold the blaster. The solution? This super comfortable and tactical foregrip. This grip has been designed to mold to the contours of your hand and features light texture on both sides to prevent hand-slip when things get intense (and sweaty). This foregrip is made up of 2 halves that clamp over the forward rail and give you a solid place to put your off-hand. The halves are held together with 2 screws (included) that make sure it doesn't move.
Kit includes muzzle, foregrip, and stock adapter
Internals add-on includes Switch plate and Lipo Battery tray
