With the LR-308's growing popularity among hunters and competitive shooters, DPMS opened the LR Series up into several other popular calibers to increase versatility. With standard A2 stock and 20" lightweight, target crowned barrel for improved accuracy and velocity, the LR-243 is built for hunting. The barrel is made of Teflon-coated stainless steel with six grooves, a 1 in 10" right-hand twist, and a Panther flash-hider. Like all DPMS Panther rifles, the LR-243 is built around a reliable gas-operated rotating bolt and an 8620 steel bolt carrier. The upper receiver is an A2-style flattop, thick walled and extruded from 6066-T6 aluminum. The lower receiver is milled from a solid billet of 6061-T6 with an integral trigger guard, a standard AR-15 trigger group, and an aluminum magazine release button. The stock is a standard A2 black Zytel Mil-Spec with a trap door and the handguards are a standard-length, ribbed free float tube. Lever safety. 19-round magazine.
