ABUOKC

Thanks for the guidance. I plan to remove/install the tube myself. I recently bought a heat gun (SEEKONE Heavy Duty) and IR thermometer (ETEKCITY LASERGRIP 630). I am curious, though. The videos I've reviewed show heating of just the outside of the receiver. Thanks again. With the information you've provided, I think I'm all set. Best regards for a Prosperous and Happy New Year.

I see that many have switched out the M4 H20 5 round magazine tube for the 7 round magazine tube. I own a fairly new M4 H20 with pistol grip and have recently bought a 7 round tube from Benelliparts.net. Here's the question: what method have any of you used to remove the 5 round tub? Has the heat altered the H20 finish in any way?
