Timber Creek Arbtbb Ar Mil-Spec Buffer Tube Burnt Bronze Ar-Platform
The Timber Creek Arbtbb AR mil-spec buffer tube in burnt bronze is a direct-fit replacement or upgrade component for AR-platform rifles. Whether you're building a new lower receiver or refreshing an existing carbine, this mil-spec tube forms the backbone of your stock assembly—the tube itself slides onto your lower's receiver extension and anchors your buttstock, buffer, and spring. Burnt bronze is that warm, earthy metallic finish that's tough enough to handle field use while looking sharp on the bench or slung across your back.
Timber Creek Outdoor Inc makes components that earn their place in working rifles. A mil-spec buffer tube means you're not fighting fitment issues; it's the standard that fits standard parts. If you're swapping stocks, tuning recoil feel, or just need a replacement tube that won't strip threads or lose zero after a season in the field, this is a no-nonsense choice.
Burnt bronze has become the go-to for shooters who want something less reflective than bare aluminum but with more character than black anodize. It hides dust, handles UV better than bare steel, and pairs well with modern furniture. Drop it into your receiver extension hardware and you've got a solid foundation for your AR carbine or rifle.
