View Full Version : Interesting tracer implementation method

Nice idea. With good material selection, the "window" piece could be strong enough to keep the barrel rigid. Obviously, great axial care would be needed to keep the barrel sections aligned, and I wonder how leaks are avoided along with flow discontinuities as pressure increases from upgrades.

Very interesting, but wouldn't the BB, as it rides the "ceiling" of the bore due to hopup, hit the front barrel's lip after crossing the window? Maybe the Japanese type explains all that.

Google-translated version. Not very good, but it gets the point across. I like the engrish, "corresponds to also the custom cancer/gun above 9.6V"...
Do they chop the entire barrel to insert the transparent part, or only part of it?

That's interesting. It looks like, if I'm understanding the translation right, they took the inner workings of the Marui tracer unit, put the clear barrel window in, and wrapped it around that.
Besides the "window" part, that'd actually be a pretty easy home hack. But the window is the important part, so...

For AEGs, the BB doesn't really ride the top surface of the barrel as much as it bounces back and forth down the barrel.

Gotcha, thanks 'Wolv. Is that characteristic of skirting the ceiling true of LRB hopups though, or am I just missing the physics all together?

It seems like this thing would cause a noticeable loss of accuracy and power.

Village, yes on LRB.
