LBE Unlimited ARBUFFRFL Silver Aluminum AR-15 Rifle Length Recoil Buffer

A solid AR-15 rifle length recoil buffer is one of those components that doesn't get glamorous attention, but it absolutely matters for reliability and shooter experience. The LBE Unlimited AR-15 rifle length recoil buffer is built to handle the job: it's engineered for any rifle-length buffer tube setup, comes loaded with five internal steel weights, and is manufactured right here in the USA. If you're running a rifle-length system (as opposed to carbine or pistol length), this buffer absorbs and dissipates recoil energy to keep your action cycling smoothly and predictably, shot after shot.

LBE Unlimited has built a solid reputation for producing straightforward, no-nonsense AR parts that work. This buffer's aluminum construction with internal steel weights is the standard approach for a reason: it's proven, reliable, and delivers the mass and damping characteristics that rifle-length systems need. Whether you're assembling a new build, upgrading an existing rifle, or keeping spares on hand, this is the kind of component that earns its place in your parts bin through consistent, dependable performance.

Made in the USA, the LBE buffer fits any rifle-length buffer tube and pairs with standard rifle-length springs. It's a straightforward swap if you're refreshing your action or fine-tuning your build's behavior.
