Nice work with the pictures and vid. Glad you got the cant fixed.
Something I don't understand: Are you saying that your barrel was fine prior to removing the side rails? Why are your side rails still on, if you removed them?
Thank you Kansas boy. Yes it was fine before. It does feel great in hand as I can grip the gun more but two issues arise once the rail is gone.
1. Only the middle screw is held by a square plastic bock that resides inside the upper. Without it, the gun is left with a big hole and the piece that was holding it rattles inside the gun.
2. If you decide to put the screw back on with the block inside, you now have three screws all sticking out like sore thumbs.
It bothered me that's why I put it back on.
