I've used copper tubing like 2dBat. For the front sight on one I cut the sight base off a trashed Mauser barrel (I think it was a '93 Argentine) and soldered it on he tubing. The second one I bought the front sight base from Numrich, cut the ring part across the bottom so I could spread it apart, slipped it over the tubing and squeezed it back together, then soldered it in place. The tubing is slightly larger diameter than a Mauser barrel, so there's a small gap in the ring. For a bushing I found a nut that would slip over the airsoft barrel, then ground down the outside until it would slide into the copper tubing. Then I epoxied it in place. Which it where the project stopped, because epoxy got inside the opening on the nut and the airsoft barrel won't go through it. One of these days I have to get a long enough drill to get in there and clean it out.

Volks its so gratifying to hear your stories of missteps and blunders. Gratifying because it reassures me that I'm not the only one who fairly consistently does such things. Back when my son was 10 (He's 31 now). We made a plywood Panther tank in the garage for use in a Paintball game. It ended up about 1/2 scale which was still quite large. As I was building the fake tread wheels (using cut down MacDonald's 5 gallon pickle buckets). My son kept saying I was doing it wrong (I of course ignored him). Once done I went to hang them on my chassis. I had built them identically which is to say I had two left sides. Oops! My son reminds me of that screw up all the time.
Once done it was actually quite cool. For the event we had 3 completed. They had two motorcycle wheels in the center with small caster wheels in the corners. Two people could fit inside and the plan was for them to be flintstone powered. Once in the field in tall grass and with the Panther side skirt the fact that the treads didn't turn was not really noticeable. Unfortunately other than on pavement they were too heavy to push around with just the two guys inside. The four or five attached Infantry hiding behind provided most of the power.
That build was a huge learning experience for me and a great father son project.

Volkssturm, that is how I get the mauser front sight over the m4 barrels since the diameter is much larger. I cut the band at the bottom, spread it over the m4 barrel, and epoxy it in place.
I actually have a piece of copper tubing from Home Depot I thought about using, but I wanted something a little stronger with a thicker side wall.
