Recently I stumbled by some 1.5in SDR21 pipe at lowes but then I noticed that it was really dirty and had lots of discolored spots.Im guessing its been sitting there for a couple of years.I need to now if this is safe to use on a pneumatic as a barrel at 125psi.

as a barrel it would be ugly (by the sound of it) but it should be fine, as it will not be holding 125psi it should be fine unless you have uber tight fitting ammo which refuses to move then the shock pressurization could cause the barrel to explode but this is super unlikly. although if you drop it it could shatter or something. maybe you could just ask if they have some more?

I know that but I dont have any acsess to sch80 and I dont really want to order it online but if it necessary I will do that.

Edit:I didnt see ALIHSGREAT's post,Im glad to hear it will be okay and I will ask them if they have any more thats cleaner.If they dont Ill just give it a bath and if that doesnt work Ill paint it.

Ask them is they have any newer pipe as you don't want aged pipe for any cannon use,especially when it has a thin wall like SDR21.

Go to a different pipe store?

sleeve it, if you dont want to or cant find 2" sch80, it'll be fine as it is, its for a barrel and golf balls usually slide nicely in it so i wouldnt worry.
I bought a signature twice because I was an idiot. 600 bux =(

My only would worry would be if it was stored in the sun.
If not lacquer thinner or PVC cleaner will take off the stains.
