Awesome discovery I made with 16mm conduit

(I'm sorry if this mod has already been done.)

As you probably know, 16mm conduit comes in 4 metre lengths and there's this thing on the end of it which joins two bits of 16mm conduit together (like a coupler).



So if you cut that off and put it on your gun it acts like a coupler, so now there will be no hassle with putting 15mm PVC onto your barrels.

You can buy 16 mm Conduit couplers... However if you can't find them or if they aren't available to you than this a good way to solve that.

That's cool. It's usually there so people can connect more pipes up when building stuff.

Hayman's Electrical is your best bet for 16mm conduit.

Or you can use a heat gun.
