LR-308 Side-Charging Upper Assembly – 20″ Black Nitride Heavy Barrel, 1:10 Twist Rate with 15″ M-LOK Split Rail Handguard

Description

Full 20″ .308 performance with charging that stays on the right side.

Built for shooters who want every bit of velocity a .308 can give, this LR-308 upper pairs a 20″ heavy-profile barrel with a full rifle-length gas system for a smooth, soft-shooting cycle. The 4150 chrome moly vanadium barrel is finished in black nitride for corrosion and wear resistance, runs a 1:10 twist that stabilizes the most common .308 bullet weights, and wears a spiral flash hider on 5/8×24 threads. A 15″ M-LOK split-rail handguard gives you room for a bipod, light, and sling, while the Gen 2 right-side charging handle lets you work the action without taking your eye off the glass.
