Choate's AR-15/M-16 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 has a nonslip hard rubber butt plate and three places to attach a sling -- one on the bottom, a slot through the stock and a detachable sling swivel in the middle which can be moved from one side to the other. The aluminum recoil buffer tube and storage compartment caps are powder coated in a matte black finish. The stock will support the weight of the front tire on a full-size pickup truck. It also will withstand the recoil from hundreds of rounds of 12-gauge, 3-inch magnum buckshot and slugs.
