Luth-AR Lo-Drag 16" Bull Barrel AR-15 Upper Receiver 1-7 Twist

Luth-ar Lo-Drag Classic Bull Complete Upper Features The Luth-ar Lo-Drag Classic Bull Complete Upper centers on a 16 bull barrel profile that adds forward weight for stability which helps tame recoil and keep the muzzle steadier between shots. Made from 4150 chrome moly vanadium steel the barrel is built for durability and long service life under repeated firing. Its 1-7 twist rate is matched to heavier bullet weights giving the shooter a barrel suited to long-range precision work rather than light varmint loads. The button broached rifling while not chrome lined keeps bore dimensions tight and consistent for repeatable accuracy shot after shot. The Lo-Drag flattop receiver is machined from 6061-T6 extruded aluminum and finished in a hard coat anodized Black giving the upper a durable corrosion-resistant exterior that holds up to field use. It includes the Luth-AR bolt carrier group built from an 8620 steel carrier a 4340 alloy steel cam pin and a 4130 alloy steel carrier key with the Carpenter 158 bolt and 4140 alloy steel extractor both given Army spec heat treatment and a manganese phosphate finish for corrosion resistance. The M4 feed ramp geometry improves feeding reliability across a range of magazines and ammunition. Together these components make the Luth-ar Lo-Drag Classic Bull Complete Upper a ready-to-run option for shooters assembling a precision-oriented AR-15 build.
