>>5451719From what I've seen, most people here don't do barrel replacements.
It really depends on what sort of blaster
you.re working on.
For air guns like buzzbeebigblast s or titans you want about a foot of petg piping nested inside pvc for sturdyness.
I've got no effing clue where to get petg anymore. But believe me, it's good shit.
For clip stuff like longshots, you're gonna have to rebuild the entire breech, most people use brass for this, it's complex though, so you're gonna have to do some research on that one. Just search "nerf brass breech" and plenty should show up.
For single shot pistols, petg will still work. Or a short piece of copper or brass. But my favorite solution is to rip off the top and end cap of a crayola marker, still it out with a 1/2 inch drillbit, and use that. Makes for a snug fit.
