The Lo-Pro Classic might look simple with its standard handguards and slick-sided upper, but it'll shoot circles around the competition without denting your wallet. The Lo-Pro Classic has a button-rifled, 16" 4140 chrome-moly steel bull barrel with 6 grooves and a 1 in 9" right-hand twist. Like all Panther rifles, it's built around a reliable gas-operated rotating bolt and a 8620 steel bolt carrier. The 6066-T6 aircraft aluminum upper receiver features a Lo-Pro Extruded flattop design and the 7075 T6 aircraft aluminum lower receiver features a semi-auto trigger group, an aluminum trigger guard, and an aluminum magazine release button. The stock is an A2 standard black Zytel fixed model with a trapdoor assembly and the handguards are oval, carbine-length GlacierGuards with an aluminum Delta Ring. 30-round magazine. Lever-style safety.
