Description

Want an LR-308 that looks as good as it performs? Want to develop that “extension of yourself” level of familiarity that only building it yourself could grant you? Get your zen on with this LR-308 upper assembly, with a black nitride barrel that’s been given straight fluting to show that attention-getting stainless steel underneath.

This side-charging LR-308 upper assembly comes with a pre-built side-charging upper assembly that features a 20-inch black nitride straight-fluted Heavy Barrel paired with a 15-inch free-M-LOK floating handguard. Once you complete your LR-308 (DPMS gen 1 patterned) 80% lower, you just build it, and mount the backup sights or optic of your choice.
