Hi What is the secret to removing the tube? I used a torch to heat the tube from the receiver side but still could not get it to loosen. Also, the plastic guide on the barrel side of the receiver is plastic so obviously not torch/heat friendly. That plastic part seems to be glued to slots in the receiver? There is also a plastic retaining ring around the shot tube. Those plastic parts seem cheap and available so maybe I need to replace them after swapping tubes??

Does anyone sell the newer sync mount for the RMR in FDE? Also, does anyone have any of older BOR 100s for sale? I think older mount looked much better even if it may not function as well.
