Barrel Spring 12in x 2.5in x 125#

The Barrel Spring 12in x 2.5in x 125# from SWIFT SPRINGS is a heavy-duty compression spring engineered for precision firearm assembly, recoil management systems, and tactical weapon platforms. Built for law enforcement and military applications where reliability under sustained firing cycles is non-negotiable, this spring delivers consistent force delivery across thousands of rounds. Whether you're maintaining duty rifles, building custom tactical platforms, or servicing military-grade hardware, this spring provides the predictable performance operators depend on in the field.

This barrel spring features a 125-pound force rating, meaning it exerts consistent compression force throughout its 12-inch length and 2.5-inch diameter, making it suitable for high-stress mechanical applications in tactical systems. The spring's robust construction ensures it maintains tension integrity across temperature extremes and extended operational periods—critical factors in field conditions where spring fatigue can compromise weapon function. SWIFT SPRINGS' manufacturing tolerances guarantee uniform coil spacing and wire diameter, preventing binding and premature wear that plague inferior springs in duty applications.

Operators maintaining AR-platform rifles, precision rifle builds, and modular weapon systems will recognize this spring's utility in buffering assemblies and recoil mitigation setups. The 3.4-pound weight provides meaningful mechanical advantage without destabilizing firearm dynamics. Installation requires basic armorer knowledge and standard spring-handling tools; replacement intervals depend on round count and platform design. Law enforcement armorers, military gunsmiths, and precision shooters sourcing replacement springs for in-service rifles benefit from SWIFT SPRINGS' reputation for consistency and durability in high-cycle applications.
