boof Posted September 11, 2020 Share Posted September 11, 2020 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??

Scout_21 Posted September 11, 2020 Share Posted September 11, 2020 Yeah I bought replacement plastic parts and the ring as it did take a fair amount of heat to break the red loctite loose and those parts got burnt in the process. Quote Link to comment Share on other sites More sharing options...
AIRB0RNE6176 Posted September 13, 2020 Share Posted September 13, 2020 I was able to change out my original mag tubes to the 7 shell tubes by using a heatgun with a small nozzle attachment to precisely direct heat to the outside metal of the receiver. Heated up enough quickly to loosen up the red threadlocker (lots of it) and was fortunate not to damage or warp the plastic parts and my M3. Did this for both the M3 and M4, even though our unit's armorer/gunsmith said to use a torch... 1 Quote Link to comment Share on other sites More sharing options...
