I have one on all my ar pistols and rifles - Armaspec AR-15/AR-10 Stealth Recoil Spring

I was a little bit skeptical at first but then I’m sold after running the first magazine with the silent capture spring installed. I don’t know about you, but that little twang from the traditional buffer spring. After installing this product, all you’re gonna hear is the rifle going off. in addition, your AR15 is gonna cycle faster, smoother, and there will be a noticeable reduction in recoil. I would highly recommend this product.
