Cmmg Spring Action Ar15 Carbine

The CMMG Spring Action AR-15 Carbine is a high-quality replacement action spring specifically designed for AR-15 platforms. This carbine-length action spring is essential for maintaining the proper tension required for reliable cycling of the bolt carrier group, ensuring consistent performance during semi-automatic fire.

This spring plays a critical role in governing bolt carrier velocity and return timing, making it a vital mechanical component. A worn or compromised spring can lead to sluggish bolt operation and inconsistent cycling, which can negatively impact accuracy and reliability. CMMG's manufacturing tolerances ensure that this spring meets AR-15 MIL-SPEC parameters, making it suitable for both duty applications and precision builds.

Ideal for armorers and gunsmiths, this spring is a verified component that outperforms generic alternatives. It fits standard AR-15 receiver extensions without modification, making it a convenient choice for maintenance and repairs. Keeping a spare on hand is advisable for field repairs or as part of a dedicated maintenance kit.
