LBE Unlimited CBUFKIT 6-Position Commercial Buffer Tube Kit for AR-15 - Black

The LBE Unlimited CBUFKIT 6-Position Commercial Buffer Tube Kit for AR-15 is a straightforward, no-frills upgrade for shooters who want a modular stock solution without breaking the bank. This commercial buffer tube kit gives you the flexibility to choose your own stock and grip configuration, making it an ideal choice for AR-15 builders, gunsmiths, and anyone looking to customize their platform rifle to fit their specific needs—whether you're setting up a patrol rifle, sport shooter, or home-defense AR.

The 6-position design lets you dial in the length of pull that works for your body mechanics and gear setup. Unlike integrated stock systems, a buffer tube kit puts you in control: pick the buttstock, grip, and accessories that match your mission. This approach appeals to experienced builders and those who want to avoid the one-size-fits-all compromises of factory setups.

LBE Unlimited has built a reputation for delivering practical, durable AR components at reasonable prices. This kit handles the mechanical backbone—buffer tube, spring, and detent hardware—so you can focus on selecting the rest of your setup. Black finish resists corrosion and blends with most modern AR builds.

• 6-position adjustable length of pull for personalized fit
