This LWRC SIX8-SPR rifle in 6.8mm SPC II and black finish is built to a California-compliant configuration (brand part no. SIX8RB16SPRCAC), pairing proprietary upper and lower receivers optimized for the 6.8 SPC II cartridge with a magazine release via a Juggernaut Tactical rear takedown pin. LWRC cold hammer-forges the 16-inch heavy barrel and nitride-treats it, cutting the rifling at a 1-in-10 right-hand twist and running an adjustable 2-position gas block. An LWRCI birdcage A2 flash hider caps the threaded 5/8×24 muzzle, and LWRCI Skirmish back-up iron sights pair with an enhanced fire control group for a crisper trigger pull. A 12-inch user-configurable rail system, an ambidextrous charging handle, and a fully ambidextrous lower receiver round out the controls, while an LWRCI adjustable compact stock and a Magpul MOE+ grip complete the ergonomics. Unloaded weight runs 6.95 to 7.25 pounds depending on configuration, and the rifle ships with extra Picatinny rail sections for attachments. Among AR rifles, this SIX8-SPR configuration favors California shooters who want a purpose-built 6.8 SPC II platform in a legal configuration.
