“Sunset” .300 Blackout Carbine Lower Kit – Team Dream Build

Features

• Lower kit based on the Sunset Team Dream Build .300 Blackout carbine configuration
• AT3 Tactical AT-15 forged lower receiver gives the build a dependable AR-15 foundation
• Armaspec Sound Mitigation Buffer provides a captured buffer setup for a smoother, quieter recoil system
• Ballistic Engineering Accurized adjustable single-stage trigger allows a lighter, more refined trigger pull
• B5 SOPMOD stock and Ergo Deluxe grip give the lower a comfortable, substantial feel
• Timber Creek oversized trigger guard, ambidextrous safety, extended magazine release, and takedown pins upgrade the control layout
• Standard AR-15 magazine compatibility works with .300 Blackout when proper ammo and magazines are kept clearly separated
• Inspired by the original Sunset employee build, which was Cerakoted in Copper, Blood Orange, and Polar Blue

The “Sunset” .300 Blackout Carbine Lower Kit is the stocked lower half of the Sunset Team Dream Build, built around comfort, control, and a tuned recoil setup. The Armaspec Sound Mitigation Buffer, adjustable trigger, B5 SOPMOD stock, Ergo Deluxe grip, and upgraded controls give this lower the feel needed to match the short, lightweight operating system used in the Sunset upper. Inspired by a custom employee build Cerakoted in Copper, Blood Orange, and Polar Blue, this lower keeps the same flashy range-build personality while leaving final assembly and finish choices up to the builder.

Note: This product page is for the lower kit only. The matching Sunset .300 Blackout Carbine upper kit is sold separately and can be paired with this lower, but assembling these components in the intended Dream Build configuration creates a short-barreled rifle. NFA rules and processes apply, and it is the purchaser’s responsibility to ensure any final configuration complies with all applicable federal, state, and local laws before assembly.

Kit Note: This product is sold as a parts kit, and final assembly is up to the purchaser. Parts and accessories are subject to change due to unforeseen shortages, compatibility updates, or compliance changes. Any substitutions will be of equal or greater value and will be noted in this product listing. Cerakote or custom finish work is not included – All parts for this build are standard black.
