The JE Machine Tech TS-ABT28B .308 Carbine Buffer is a direct drop-in upgrade for AR-10 and DPMS LR-308 style rifles that use a standard carbine-length buffer tube. Machined from aluminum with a low-glare black oxide finish, this solid, no-rattle buffer is built to deliver smoother cycling and quieter operation at the rear of the rifle.

This .308 carbine buffer is ideal for builders and shooters who want to refine reliability and shooting feel on AR-10 and .308 Winchester carbines. Its solid internal weight helps the buffer track consistently under recoil, while the pinned rubber bumper cushions impact inside the receiver extension to reduce noise and wear. Whether you are assembling a new rifle or refreshing a well-used build, the TS-ABT28B offers a straightforward, dependable upgrade backed by JE Machine Tech’s reputation for practical, purpose-built components.
