The Remington 12 Gauge Magazine Tube Extension Support With Swivel Stud For Rem 870 XCS is engineered to stabilize the magazine extension on 12-gauge 870 XCS shotguns. Built to OEM specifications, this steel support clamp secures the extension under recoil, helping reduce flex, vibration, and impact-related shifting while providing a solid mounting point for a sling via the integrated swivel stud.

This dedicated 870 XCS component is well suited for hunters, range shooters, and anyone upgrading or rebuilding an Extreme Conditions Shotgun that may see wet, humid, or harsh environments. By maintaining proper alignment and tension on the magazine tube, it supports smooth feeding and long-term durability, reflecting Remington’s long-standing reputation for practical design and dependable performance.
