Hi! I am just curious about something I noticed on my new 870 express. I noticed the magazine tube is brazed, or silver soldered, I dunno. Also, I am assuming that the square piece that is on the breech end of the magazine tube is also brazed or soldered on. To further clarify, the chamber end of the barrel looks like it "rests" on this piece on top of the mag. tube. I am curious... how in the heck did they braze this piece on? I am a 10 year journeyman plumber/pipefitter, and right now I work for a refrigeration company so I literally braze everyday for eight hours on end. I can see how the mag tube was done, as there is a ring of solder around the circumference of it, however, the square piece shows no evidence, such as the bead I see around the tube. I can't see even getting a torch in there easily. I know it is a dumb question, I was just curious if maybe one of you guys could enlighten me!
