It's tough to find a lighter full-size AR rifle on the market today than the DPMS A1 Lite 20. The Standard A1 Lite 20's carrying handle and sights make this rifle as simple as it is effective. The Lite 20 is named for its 20", button-rifled, light contour, 4140 chrome-moly steel barrel. The rifle's barrel has six grooves and a 1 in 9" right-handed twist and comes standard with an A2 birdcage flash hider. The Lite 20's gas-operated rotating bolt fires smoothly and quickly and is highly durable thanks to an 8620 steel bolt carrier. The upper and lower receivers are both made of 7075-T6 aircraft aluminum and the stock is a standard A2 black Zytel with a trap door assembly. Aluminum trigger guard and magazine release button. Standard A2 round handguards. 30 + 1 capacity.
