Since I'm tired of using and buying brass for just its sliding capabilities, has anyone found a combination of pvc/electric conduit that slides well with one another? You know how 17/32 and 9/16 brass slides well with each other and creates a good seal, no gaps, but not too tight? Well I need some PVC to do that. I know bolt master zero got a working combo, but I don't remember what he used. I have a home depot and a lowes nearby so I don't want to order from any online PVC specialty stores.

thanks for any help (*ahem bolt master zero* )

I'm not sure, but I think that there's some acrylic pipes that fit really well, I think it's the pipe that fits megas and the pipe that fits micros.

If you mean tight as in like, no air escapes, I can't help you. But boltsniper used two peices of pvc for his bolt action on his rifle. I know it's probalby not what you want if you want something air tight.

Theres a size of brass that fits reasonably well within .5"PVC, but I don't know if it's as perfectly airtight as two pieces of brass that are once size off from each other. Aside from that I can't think of any standard pvc sizes that would fit well together that slide, although there are a few that could be forced within one another with a good hammer for a permanent connection.

16mm conduit usually fits in 20mm conduit, but most of conduit sizes fit inside each other over and over.

I don't know if that helps at all, but it's what I've discovered with my conduit.

You want it to be 1/2 pvc so that you can can shoot megas? I haven't found any yet but if I do I shall tell you.

He didn't mention anything about shooting megas, and 1/2" PVC is pretty common.

Don't look at me! I haven't found a good combination. Best thing I'd say to do would be to use 1/2 PVC and 1/2 CPVC. I usually use my dremel to widen 1/2 PVC so it can fit 1/2 CPVC in it. However, that won't go very deep so if you want more then 1/2in. of overlap or so, you'd have to sand the 1/2 CPVC instead.

I am just looking for a cheapo alternative to using brass so much in each and every gun I make, well excluding the barrel.

Thanks for the info peeps, I think I will try my luck again at my conduit section of lowes/home depot for 16 and 20 mm. If not I guess I will take the sanding approach.. which sounds painstakingly rediculous already!

Yea, its a pain. However, you should not have to sand very much off to get it too slide. I can sand down a barrel in 1 to 3 minutes depending on the length.

19/32" Brass is the size that fits in 1/2" PVC.
19/32 would be the size for the "gripping" stage of a telescoping brass barrel, assuming that it works like 9/16 and 17/32, which are neighbooring sizes.
