Product Overview
The LBE ARBUFF-RFL is engineered as a direct replacement for standard rifle-length buffers. Machined from aircraft-grade aluminum and finished with a durable silver hard-anodize, it’s designed to absorb and redistribute the kinetic energy of the reciprocating mass more gently than traditional heavy steel buffers. The result: softened felt recoil, reduced muzzle rise, and a smoother, more consistent bolt-carrier group (BCG) return — without adding unnecessary weight to your rifle.
This buffer is an excellent choice for shooters who want the handling benefits of a tuned buffer while preserving the natural balance and handling of a rifle-length platform.
Key Features & Benefits
Rifle-Length Compatibility: Built specifically to fit mil-spec rifle-length receiver extensions and buffer springs for perfect drop-in installation.
Aircraft-Grade Aluminum Construction: Lightweight and robust aluminum body minimizes reciprocating mass while maintaining strength and longevity.
Silver Hard-Anodized Finish: Protective coating resists corrosion and wear while providing a clean OEM look.
Smoother Recoil Impulse: Dampens abrupt buffer/buffer tube contact for a noticeably softer recoil pulse and reduced muzzle climb.
Improved Cycling Consistency: Promotes consistent BCG return, helping with reliable ejection and feeding across a range of loads.
Drop-In Upgrade: No gunsmithing needed — remove the old buffer and spring, install the ARBUFF-RFL, and return to the range.
Reduces Component Stress: Softer impacts to the receiver extension and carrier help prolong the service life of internal parts.
Maintains Rifle Balance: Provides performance improvements without the weight penalty of steel buffers, preserving weapon handling.
Specifications
Brand: LBE Unlimited
Model: ARBUFF-RFL Recoil Buffer — Rifle Length
Part Number / SKU: ARBUFFRFL
UPC: 784682014332
Material: Aircraft-grade aluminum (silver hard-anodized finish)
Compatibility: Mil-spec rifle-length AR-15 receiver extensions and standard rifle-length buffer springs
Type: Drop-in recoil buffer (rifle length)
Intended Use: Recoil mitigation, smoother BCG cycling, precision/duty/competition rifle platforms
Installation (Quick Guide)
Safety first: Ensure the rifle is unloaded, the action is open, and the chamber is clear. Remove the magazine.
Access the buffer assembly: If desired, separate the upper and lower receivers for easier access.
Remove stock components: Depress the buffer retainer and carefully remove the existing buffer and spring from the buffer tube.
Install ARBUFF-RFL: Insert the LBE rifle buffer followed by the buffer spring, ensuring correct orientation.
Reassemble & check: Reinstall the stock (if removed), perform a function check, and verify proper cycling using safe procedures.
Test fire: Conduct a short live-fire verification with representative ammunition to confirm reliable function.
If you’re unfamiliar with AR maintenance or uncertain about compatibility, consult a qualified armorer or gunsmith.
Compatibility & Tuning Notes
The ARBUFF-RFL is intended for mil-spec rifle-length systems. If you’re running non-standard gas systems, suppressed setups, short-stroke gas piston systems, or aftermarket carriers, additional tuning (spring rates, buffer weights, or adjustable gas blocks) may be necessary to achieve optimal reliability.
For suppressed use or hot loads, monitor ejection and bolt velocity—some configurations may benefit from a heavier spring or different buffer combination.
If you experience short-stroking or light ejection after installing the ARBUFF-RFL, re-evaluate spring/buffer combinations or consider an adjustable gas solution.
Performance Tips
Start with mil-spec components: Pair the ARBUFF-RFL with a mil-spec rifle spring for the broadest compatibility.
Test with your loads: Always verify function using the specific ammunition you plan to run — performance can vary with bullet weight and powder charge.
Pair with an adjustable gas block if you frequently switch between suppressed and unsuppressed fire or use a wide range of ammunition pressures.
Monitor wear: Check the buffer face and tube area periodically for signs of unusual wear or deformation.
Maintenance & Care
Clean periodically: Wipe the buffer with a clean cloth during standard rifle cleaning sessions. The anodized finish resists corrosion but benefits from routine maintenance.
Inspect regularly: Look for chips, cracks, or unusual wear on the buffer face; replace immediately if damage is found.
Store unloaded: Unload the firearm before long-term storage and store in a cool, dry location.
Why Choose the LBE ARBUFF-RFL?
The LBE Unlimited ARBUFF-RFL provides a practical, lightweight solution for shooters seeking improved recoil characteristics and smoother cycling without sacrificing rifle balance. Whether you’re building a precision hunting rifle, a competition gun, or a duty-ready carbine, this rifle-length buffer offers tangible handling improvements and reduced component stress — all as a simple, user-friendly drop-in upgrade.
Safety & Legal Reminder
Always follow firearm safety rules: treat every firearm as loaded, keep your finger off the trigger until ready to fire, and ensure the muzzle is always pointed in a safe direction. Verify that any modifications to your firearm comply with federal, state, and local laws. If you are unsure about installation or compatibility, consult a licensed gunsmith or armorer.
