Question on barrel replacement ...

Ron Wood · 05-29-2011, 12:53 AM

This is probably a really stupid question, but perhaps did the barrel come from a long receiver gun?

GT,
I have run into this problem a few times, sometimes it was so close that a little extra "elbow grease" tightened it on up, but left a gouge mark on the end of the bbl. On the others, it was necessary to file a little metal off the end of the bbl to give clearance. Be sure to check headspace after removing any metal from the end of the bbl. But you are doing this anyway after installing a bbl aren't you?

Hi Ron, nope, all short shank outfits, and parts.. I measured from the rear toggle pin to the front of the receiver face,and compared it with another perfect condition stripped receiver, and it's to within .0015" of the other...I think all that's different is the relief clearance at the barrel base of the internal rail slots on the receiver ... ?? I can only see shaving the back of the barrel a few thou to make it fit correctly.... More mesurements to follow tomorrow... I'll know a'lot more when I'm done....Best to all, til...latr...GT....

Hi To all, and Hi Hugh! Thanks for you post..... after a few hours with the digital caliper, I found out the following... The barrel I'm using hand tightens up to exactly the same extractor width distance desired by hand on three different receivers... 1920 commercial, 1920/ model 08 commercial navy, and 1917 DWM WW1 receiver... The receiver in question, 1916 navy, measures exactly the same in all regards, within .0015" everywhere... and with the very same barrel, probably 190 to 200 degrees from straight up tight... probably 180 degrees from desired position at hand tight.. So, it apperas thet I'll have to shave the shoulder, shave the barrel breech end, and deepen the chamber / headspace... Sooooo, it apprears a finish reamer, and a "go" and "no go" gauge(s) are in the future purchases or trades list... any of you guys got any spares you're willing to let go... I've got trade bait coming and going all the time!!...

... Thanks guys, this is really staring to get fun now... Now I can actually screw my own stuff up!...

... Might be time to make a barrel also... we'll see.. best to all, til...lat'r....GT
