Default Dead Air PBS-1 & 5.45 corrosive

Hey guys just wanna hear your thoughts.

I have a PBS-1 in jail right now and even though I primarily bought the can for use on my two 7.62 AK variants I am debating running it on my SGL 31-84, 5.45 gun.

I have a decent amount of civilian non-corrosive 5.45 but probably just as much on the 7n6 corrosive stuff. I'd imagine shooting corrosive ammo through one of these would be a bad idea but just wanted to hear for those of you that do what steps do you take to clean the can since most cans dont ever get cleaned. I guess the simple answer is just dont ever shoot corrosive through it but still. Any help or advice would be appreciated.

You'll want to clean the can. Maybe a dunk bath would be the best way and let it dry or just get most of the water out and shoot non corrosive through it to dry it.

Like you said, don't shoot corrosive through it unless absolutely necessary.

flush with water real well when done shooting. then use the 90/10 Ballistol/water mix. when you get home you can dunk in bucket of water as well.

Soapy water.

Thats all you need, make sure its dry before firing.

Frankly, the guts should be stainless at the least.

If you shoot "corrosive" 5.45, just dunk the can in hot water after you are done shooting it. The water will wash the acid salts out. Try not to overthink it, the corrosive salts are safe for the bore (which is under lots more psi) if you wash it with water afterwords.

As others have said--rinse it. I'd take it down as far as you can then and just check it the next day and see if you see any signs you didn't get it all. If you don't see anything under the mount then the rest should be good as well.

Why should the can be dry before firing? Just curious. I thought running cans "wet" was no big deal. I've dumped some water in my cans or sometimes some wire pulling gel, but my cans are form 1 home builds so the construction is different than most all commercial cans.

Most F1 cans are very similar in construction to F4 cans by large MFGs other than the store bought cans tend to have more consistent welds, more mounting options, ETC. Welds on a robot are so much more consistent. They both work on the same principal and devices. I know people with F1 K Baffle cans just like a Hybrid and I know of people with F1 monocore cans that are full titanium and machined by hand.

Shouldn't be any real harm to any can being run wet. I'd be more hesitate to run a rifle can wet just due to pressures and such but probably not a biggie.

All you need to do is flush it with water.. nothing else. Once you do that depending on where you live and what kind of finish is on the suppressor dry it out and maybe oil it like you would anything else.. Here in colorado I can just about put away a gun thats wet without it rusting, in Wilmington NC where my dad lives you can just about see an un oiled gun rust right in front of your eyes.

Actually, I think it was in the instructions for one of my cans, IE, not to run them wet, thinking as was mentioned, that it had something to do with too much pressure, and it could void the warranty.

Theory is, that since water is uncompressable, it could bulge the tube.

Further, it also appears it blows water back into the action, and all over your face/person.

Water, pulling gel, etc gets everywhere.

Correct. With rifle calibers liquid is a hard no-go. Pistol calibers it's fine and quieter.

Thanks guys I appreciate the help. Didn't want to overthink it but I figured running some warm soapy water would do the trick.
