Welcome to Whisper Springs

The latest in AR 15 buffer springs! Whisper Spring Technologies has combined decades of high-performance compression spring technology into their Silent buffer springs for AR-style firearms. Each time you fire a round, the proprietary Nylon coating process gives the spring the ability to compress inside the firearms buffer tube without creating harsh scraping noises. It also works when the spring decompresses and pushes the buffer and bolt carrier group forward, eliminating the ‘twang’ noise when charging another round.

Count on Whisper Spring Technologies Silent buffer springs for thousands of rounds. Simply insert your existing buffer in one end of the spring and reinstall it into your firearm. Use it with any regular ammo, subsonic ammo, .300 Blackout, suppressed firearms, or even full-auto. 

If the Silent spring ever needs to be cleaned, use mild soap and water to clean off any oils or carbon, let dry, and reinstall. The Silent buffer spring can be installed in any new or used AR in good working condition, select the right length for your application and purchase today.

Enjoy taking your AR 15 or AR 10 out to the range again with the Silent buffer spring from Whisper Spring Technologies.
