Quiets the recoil - Armaspec AR15 Gen4 H2 Stealth Recoil Spring

I installed this system into a 16" barrel and toke it to the range. I was very happy with the noise reduction, since the rifle no longer had the sound of the recoil spring dragging along the inside of the buffer tube. The reason for the 4 stars is that it is a little difficult to install into an existing rifle, trying to depress the catch and install the system is a little difficult. I would recommend this system to my friends since they have also stated they do not like the typical sound of the recoil and a JP system is a lot more money.
