Question on barrel replacement ...

"Also picked up the ideas of using a solvent like perhaps Kroil on the threads before removal attempts. Some time in the freezer as suggested before is good too I think. The Luger receiver and barrel as you know are kinda dainty really, sometimes a sharp hammer blow on the action wrench is worth more than an average sized guy jumping on the end of a 2 foot wrench."

DITTO what Rick said.

I had one bbl that twisted until the front sight was pointing DOWN before it broke loose with a loud "crack"! Often those guns that have been reblued with the "modern" dip blue have the threads rusted in.

I have found that overnight soaking in Kroil or Liquid Wrench helps loosen bbls, also , for really stubborn ones, heating the receiver area with a propane torch & then putting in the freezer overnight will help.

Thanks to all for the info shared.. I have a pretty good idea as to the necessary steps for success... but, one last question.. how far should the barrel screw on by hand, prior to wrenching it up to alignment.. I've read that the extractor width and no more is acceptible, others have told me 1/8" is enough... seems like it gets pretty tight, pretty fast!

All the "new" German field armory replacement bbls I have used would hand tighten to within a extractor slot or close. New after market bbls vary, some will come close, some won't, most will require a little turning on the face of the flange to fit. As Rick says, be sure to use lots of antisize compound on the threads and flange. I have had bbls that would require tightening and loosening several times to mate the bbl to the receiver in the correct position.

OK guys! Barrel removal is a snap... The rosin was just the ticket and my receiver wrench is work'en great... so, now I try to screw in an original barrel from another receiver, aaaannnndddd, it actually hits / bottoms out, on the receiver at / on, the breech face end of the barrel, leaving the flange about half a turn out...???....

... Is this abnormal, un-usual, or just beginners luck!
