buffer tube wear in piston rifles

[rob072770]

starting to see some buffer wear on the botton. I know this is acommon deal with a piston upper. I have a NiB carrier group. It. there a matching hardness buffer tube. None of the guns have this. Can you fix bolt rise? Or I need to get over it as part of the piston system. I do like the piston system easy to clean. It also works so well in SBRs

Primary Weapons sells a buffer tube with an extended lip that is supposed to assist with that tilt. Check it out here

You can also try a heavier buffer or a carrier weight system.
