Armaspec ECB Kit – AR-15/AR-10 Enhanced Captured Buffer System (Black)

The Armaspec ECB (Enhanced Captured Buffer) Kit replaces your standard AR-15 or AR-10 buffer and spring with a self-contained recoil system that reduces felt recoil, eliminates buffer rattle, and smooths out the cycling action. Ideal for shooters who want a quieter, more refined rifle without modifying the lower receiver or buffer tube. The captured design keeps all internal components sealed within the buffer body, preventing spring noise and simplifying maintenance.

Constructed from durable polymer and steel internals with a black anodized finish. Installation is drop-in—no gunsmithing or permanent modifications required. Simply remove your existing buffer and spring, then install the ECB kit in seconds. Compatible with standard carbine and rifle-length buffer tubes on AR-15 and AR-10 platforms.
