Want an LR-308 that looks as awesome as it performs? Got the urge to develop that "extension of yourself" level of familiarity that only building it yourself could achieve? Get your zen on with this side-charging LR-308 build kit, with a black nitride barrel that's been given straight fluting to show that eye-popping stainless steel underneath.
This side-charging LR-308 build kit has a pre-built side-charging upper assembly that features a 20-inch black nitride straight-fluted SOCOM Barrel paired with a 15-inch free-M-Lok floating handguard. Also, you get the rear end of your rifle, the 6-position buffer tube assembly and butt stock. And of course, there's a standard lower parts kit included.
