LBE Unlimited Recoil Buffer — .308 Win Carbine-Length AR-10, Silver Aluminum (Model ARBF308C | UPC 765857617718)
Optimize control, reduce felt recoil, and improve cyclic consistency in your AR-10/.308 carbine build with the LBE Unlimited Recoil Buffer (Model ARBF308C). Designed specifically for .308 Winchester / 7.62 NATO carbine-length gas systems, this precision-engineered buffer delivers smoother bolt carrier return, reduced muzzle rise, and improved shooter comfort without compromising reliability. Machined from lightweight, durable aluminum and finished in a corrosion-resistant silver, the ARBF308C is a simple swap that yields measurable improvements for hunters, competitors, and tactical shooters alike.
Built for .308 Carbine-Length Systems
Unlike universal buffers, the ARBF308C is purpose-tuned for the mass and gas timing of carbine-length AR-10 platforms chambered in .308 Win / 7.62 NATO. That targeted design helps moderate the unique impulse characteristics of larger calibers—softening bolt impact against the rear of the receiver and delivering a more controlled, consistent cycling rhythm across a wide range of factory and handloaded ammunition.
Key Benefits & Performance Improvements
Reduced Felt Recoil: Absorbs and spreads rearward energy to lessen sharpness of recoil impulse, improving comfort during extended strings of fire.
Improved Muzzle Control: Damps muzzle rise for faster follow-up shots and better target recovery.
Smoother Bolt Carrier Impact: Lessens bolt hammering on the buffer tube, reducing mechanical shock and perceived “snap.”
Enhanced Reliability: Promotes more consistent carrier timing and helps reduce bolt bounce or timing-related malfunctions when tuned with the correct spring.
Lightweight Durability: Aluminum construction reduces unnecessary mass while providing rugged longevity.
Premium Construction & Finish
Material: Precision CNC machined from high-grade aluminum for strength, dimensional accuracy, and reduced weight compared to steel buffers.
Finish: Durable silver anodized/coated surface for corrosion resistance and a clean, professional appearance that complements stainless or silver-accented builds.
Form Factor: Carbine-length profile sized to fit standard AR-10/.308 buffer tubes and interface reliably with common carrier geometries.
Ideal For
AR-10 / .308 carbine builds (carbine-length gas systems)
Precision shooters and hunters wanting improved recoil management and faster follow ups
Competition shooters in PCC/centerfire classes using carbine-length setups
Law enforcement and tactical users seeking reliable, repeatable operation under varied loads
Gunsmiths and builders tuning buffer/spring combinations for optimal performance

Compatibility: Standard AR-10 carbine buffer tube and bolt carrier groups (verify carrier fit and spring pairing for your specific lower/upper combination)
Installation & Tuning Notes
Safety first: Ensure firearm is unloaded and the upper is separated from the lower before working on the buffer assembly.
Remove the existing buffer and buffer spring from the buffer tube.
Install the LBE ARBF308C with the proper carbine-length recoil spring recommended for your AR-10 configuration.
Reassemble and perform a function check. Confirm the rifle cycles reliably with your typical ammunition range (from light loads to higher-pressure rounds).
Fine-tune spring weight or buffer length if necessary — .308 AR variants vary; pairing with the correct spring (or aftermarket spring) may be required for optimal reliability and reduced felt recoil.
Note: Because AR-10 platforms and bolt carrier groups vary by manufacturer (weight, gas system timing, and buffer tube dimensions), always verify fit and function in your particular rifle. If uncertain, consult the rifle or upper manufacturer’s recommendations or a qualified gunsmith.
Care & Maintenance
Clean periodically to remove carbon and fouling that can build up around the buffer and spring.
Inspect for wear or damage—replace if unusual deformation or excessive wear is observed.
Keep the anodized surface clean and lightly lubricate contact surfaces as part of regular rifle maintenance.
