Runs smoothly - JP Enterprises Gen 2 Silent Captured Buffer Spring System

This is my second JPE buffer spring system. I have one in my Radical RF15 and I got one for my Aero M5 build. I know it has o-rings that will need replacing, but these don't reside in my SHTF rifles, I use them for 2-gun and gas PRS. My M5 dry weighs in at 17lbs close to 18-19ish with seeds and between the buffer system and the weight of the rifle I would say it's an easy 40%-ish decrease in "felt" recoil when compared to the standard buffer setup. I say "felt" because that is what it feels like to me, you may have a different experience from mine.
