Orion Posted April 23, 2018 Author Report Share Posted April 23, 2018 Thanks Eric, I have a lot of movement but it operates fine; I just want to make sure it will not cause any excessive wear issue's. Andy Link to comment Share on other sites More sharing options...

AndyIs your WW2 or WW1 ??? Should be easy to replace WW2 and it should be tight. I would correct that issue.Eric Link to comment Share on other sites More sharing options...
emmagee1917 Posted April 23, 2018 Report Share Posted April 23, 2018 (edited) Should wiggle a little . There is only a couple of thousandth clearance between piston and cylinder , far too little for a ridged rod of that length to hold . As the piston enters the cylinder , gas pressure will cause it to find it's own center . Same for coming out . This is why you see pics of Marines stripping their BARs after a beach landing , one grain of sand there will lock her up . Otherwise , she's about bulletproof .Chris Edited April 23, 2018 by emmagee1917 Link to comment Share on other sites More sharing options...
