Yeah that was way worse than the mag tube
I tried for like 10 minutes with the trusty harbor freight heat gun but I didn’t feel like getting cramps holding it up all day as I didn’t feel any progress. Went to Home Depot and saw a Bernzomatic FLAME COMMANDER and figured that’d do the job swimmingly with a name like that. Took like 5 minutes of very very careful heating as I tried my hardest to avoid discoloring the receiver finish. Cleaned off all the old gunk afterwards easy peasy with a brass wire brush. No issues on the receiver and it runs.
If any fellas plan to do this, go straight to the torch and aim at the recoil tube, not downward at the receiver. I heated it in one spot, occasionally moving to a new spot after trying to make it budge with a wrench. Don’t use a channel lock like an idiot like I tried to, get a 1 1/16 wrench, ideally adjustable so you can turn the tube itself after you take off the nut on the receiver.
