LBE Unlimited Standard Recoil Buffer — Carbine Length AR-15 — Silver Aluminum (Model ARBUFF, UPC: 765857617350)
Optimize your AR-15’s reliability and feel with the LBE Unlimited Standard Recoil Buffer — Carbine Length (ARBUFF). Machined from high-quality aluminum and finished in a durable silver tone, this carbine-length recoil buffer is a direct, drop-in upgrade or replacement for builders and shooters who want consistent cycling, reduced felt impulse, and long service life from their carbine-length AR-15 platform.
Precision Machining & Rugged Construction
The ARBUFF is manufactured to precision tolerances for a repeatable fit inside a standard carbine receiver extension. Constructed from robust aluminum and surface-finished in silver, the buffer resists corrosion and wear while offering a lightweight, durable alternative to heavier steel buffers. Its solid construction ensures it withstands repeated cycles and the stresses of everyday range use or duty carry.
Designed for Carbine-Length Systems
Specifically built for carbine-length AR-15 systems, the LBE Unlimited recoil buffer functions optimally with standard carbine buffer springs and carbine receiver extensions (6-position or fixed). It’s fully compatible with most mil-spec and commercial AR-15 uppers and lowers that accept a carbine-length buffer assembly. Whether you’re assembling a lightweight patrol rifle or a comfortable range gun, this buffer integrates seamlessly into your build.
Performance Benefits
Improved Felt Recoil & Muzzle Impulse: The buffer helps smooth the rifle’s rearward energy transfer for a more manageable shooting experience and quicker follow-up shots.
Reliable Cycling: Precisely cut dimensions and concentricity contribute to consistent bolt carrier group velocity and reduced malfunctions due to timing variances.
Durability: Aluminum construction gives exceptional fatigue resistance and longevity without the corrosion concerns of untreated metals.
Lightweight: Keeps overall rifle mass down for easier carry and faster handling — ideal for hunters, competition shooters, and operators who prefer a nimble carbine.
Installation & Compatibility Notes
Easy Drop-In Installation: Removes and installs quickly with standard armorer tools. No gunsmithing required for most builds.
Works With: Standard carbine receiver extensions, carbine buffer springs, and mil-spec carbine bolt carrier groups. Confirm your platform uses a carbine-length buffer system before installation.
Not Intended For: Rifle-length or pistol-length buffer systems — verify your rifle’s specification prior to purchase.
Safety: After installation, perform function checks and verify proper cyclic operation and headspace; consult a qualified armorer if unsure.
Ideal Applications
AR-15 carbine builds (civilian, duty, competition)
Lightweight hunting and patrol rifles where reduced weight matters
Builders swapping components for tailored recoil profiles
Shooters seeking consistent performance from a reliable buffer component
Care & Maintenance
Keep your LBE Unlimited ARBUFF functioning at its best by inspecting for wear during routine cleaning. Wipe down the buffer, make sure threads and mating surfaces are free of heavy fouling, and lightly lubricate contact areas per standard AR-15 maintenance procedures. Replace springs or associated parts that show fatigue or deformation.
