Sprinco M16 Rifle Buffer Spring, Chrome Silicon, Stand-Alone

The Sprinco USA M16 Rifle Buffer Spring (Sprinco part no. 25001) is a stand-alone replacement spring wound from chrome-silicon (CS) wire and sized for the rifle-length buffer tube used on M16-pattern uppers. The buffer spring stores and returns the energy that drives the bolt carrier group forward into battery after each shot, and Sprinco’s chrome-silicon wire resists the fatigue that gradually weakens standard music-wire springs.

Key Specifications

• chrome-silicon (CS) spring wire resists the fatigue that gradually weakens standard music-wire buffer springs.
• sized for the rifle-length buffer tube used on M16-pattern uppers, not the shorter carbine tube.
• sold as a stand-alone spring so it drops into an existing buffer tube without other parts.
