Fell apart after ~500 rounds/2 weeks. - TANDEMKROSS Shock Block Bolt Buffer for Ruger PC Carbine

Needs a major design overhaul. The aluminum piece (red) is only as big as you see it. The rest of it is just two pins that only go 1mm into the aluminum and that's what holds the rubber shock absorbing piece against the red aluminum block (that's a 4 piece buffer design!). Imagine the force the pins that only go 1mm into the red aluminum part experiences. My PCC jammed up and wouldn't cycle/couldn't pull the bolt back because the pins that barely go into the aluminum block fell out so the whole rubber section was just sitting loose inside the action, preventing the bolt from cycling back. At least the OEM recoil buffer is a single piece of plastic. Do not buy unless you want to replace potentially after a single shot.
