    All I can say is if you have a BCM buffer tube installed and use this buffer spring there will be no "spring noise" when hitting the bolt release.

    Solid spring

    Purchased a decent AR pistol build kit with a terrible gas block. Wouldn’t cycle, failed to feed, weak ejection and it jammed occasionally when it did try to feed... purchased BCM Gas block, buffer (H) and buffer spring. Build runs FLAWLESSLY NOW! AWESOME PRODUCTS! Should’ve brought an entire BCM build kit from the get go...

    It’s a spring. Runs in concert with H3 Carbine Buffer on 300 BLK pistol. It works. Standard issue BCM goodness. Ships fast, too. Would definitely recommend.
