Armaspec ECB Slant Kit – AR-15/AR-10 Enhanced Captured Buffer Spring

The Armaspec ECB Slant Kit replaces your standard AR-15 or AR-10 buffer and spring system with a captured spring design that reduces felt recoil, eliminates buffer spring noise, and smooths out the cycling action. The slant cut design allows for tool-free installation and removal without disassembling the lower receiver—simply insert at an angle through the receiver extension opening. This kit is ideal for shooters looking to improve recoil management and quiet their rifle's action without permanent modifications.

The ECB features a hardened steel buffer body with a black finish and uses an internal captured spring assembly that won't bind, kink, or generate the metallic twang common with mil-spec springs. Installation is drop-in with no gunsmithing required. The slant cut configuration means you can swap buffers without removing the stock or castle nut, making tuning and maintenance significantly easier.
