Axem Buffer 5.56 Carbine is a buffer for the AR-15 platform, designed for carbine-length receiver extension tubes and compatible with 5.56x45 NATO/.223 Rem caliber systems; it is suitable for firearm maintenance, as a spare part, and for builds where reliable cycling and balanced motion are desired. Compatibility with the 5.56 AR-15 platform and carbine-length design make installation smooth for most AR-15 configurations.
The construction features an aluminum body, steel internal weights, and an elastomer bumper, which together dampen the extremes of bolt carrier movement and support operational reliability. Precisely machined body and wear-resistant finish are designed for demanding use, ensuring smooth motion and consistent return with the correct spring.
The carbine-length buffer works in tandem with a standard carbine buffer spring and fits both mil-spec and commercial-type carbine buffer tubes (internal dimensions compatible). Polyurethane bumper and roll pin attachment ensure end cap durability and maintenance reliability. An anodized or otherwise hard-treated surface reduces wear and facilitates smooth motion within the receiver extension tube.
