The KE Arms Buffer Tube Kit is a complete rear-end assembly solution designed for AR platform builds and upgrades, providing all necessary mil-spec components except the buttstock. This kit is ideal for builders looking to source matched, quality-controlled buffer tube components from a single manufacturer, ensuring reliability and performance.
The kit includes a mil-spec buffer tube, KE Arms steel endplate, a 3-ounce carbine buffer, buffer spring, and steel castle nut, all manufactured in the USA. The robust steel construction of the endplate and castle nut ensures durability and stability during repeated disassembly and cleaning cycles, making it suitable for law enforcement and serious-use environments.
This kit is particularly beneficial for operators who prioritize domestic manufacturing and component traceability, as well as builders upgrading worn-out rear assemblies or completing 80-percent builds. Its lightweight design of 0.75 pounds reflects a balance of strength and efficiency, making it a practical choice for constructing new platform rifles from the ground up.
