Barrel replacement 1917 DMW

[Lugerdoc]

Scott, You may be in for a frustrating but interesting experience. All of the currently available luger replacement barrels that I'm aware of, do come with the cut for the extractor & feed ramp. In the case of the Sarco LPO8 barrels, the extractor cut may not be lined up with the front sight base &/or the rear sight base. I returned 8 out of a dozen ordered, due to these 3 items not lining up. The "notch" that is refered to above, it on the front of the receiver and should line up with the rear sight base of the LPO8 barrel, so that the rear sight will be able to lay down to it's designed 50m position. Most of the barrels that I have received from Numrich are short chambered and many gunsmiths perfer this so they can do the final chamber ream for the correct head space, which may vary depending of breech block dimentions. When installing any luger barrel, you may have to "fudge" a bit on lining up the barrel extractor cut (which can be opened up) with the cut in the receiver, to insure that the front sight base is perpendicular. This is something that an experience eye can pick up better than any tool. Finally, you will probably have to make some brass shims to adapt the hole in your vise to the diameter of the luger barrel that your are installing/removing, and you should make sure that the barrel is clamped as far to the rear as possible to avoid twisting it, as may have been done on your original one. If you decide to give up, let me know as I've been installing them for over 20 years. Lugerdoc
