Choate's 12-gauge Side Folding M4 Telescoping Stock has been designed withstand the recoil from hundreds of rounds of 12-gauge 3-inch magnum buckshot and slugs and can be used while stock is folded. This stock is sold as a kit and includes the 870 12-gauge side folding housing, stock, buffer tube, and locking nut. This five position telescoping stock has two storage compartments with O-ring sealed screw-in caps. The storage compartments are water tight and will hold two AA or three 123 Lithium batteries in each side. The stock features an ergonomic cheek piece that fits and feels great against the shooter’s face. The stock has a non-slip hard rubber butt plate and three places to attach a sling, one on bottom, a slot through the stock, and a sling swivel in the middle which can be moved to either side. The aluminum recoil buffer tube and storage compartment caps are powder coated in a matte black finish.
