Thread: Ammonia in supressor!

Just took my suppressor off after giving it a workout over the last couple of days. Unscrewed the base (its a DPT modular) and the smell of ammonia made my eyes water took the front baffle off and got a second dose. I have read somewhere that ammonia and aluminium don't get on so anyone know what causes this and how to stop it doing any damage.

That would probably be the powder residue that you can smell, seeing it is a modular suppressor you could always give it a clean with hoppes no9 if it is concerning you

Ammonia and aluminium are quite happy together. I work with the shit everyday and we use ali gaskets and other component. Im not 100% with aqueous ammonia but would not expect much difference.

Ammonia probally cant hurt, Ruskis used to piss down their mosin, mind you thats steel rather than duralium.

It tells you about this on the info sheet DPT supps come with doesnt it?

come on thats reading the instructions

I can read instructions, it's just like most blokes I choose not to and by now they will have binned along with all the packaging.

And that would be uric acid

You should try shooting a few mags through an AR15 without an adjustable gas block or a gas busted charging handle if you want to make your eyes water with ammonia fumes.

I was joking but not sure if your actually offering to send me bottled urine..? Free shipping?

Are you running full powder loads or what is the brand of powder.We run 5 baffle Tok Cans with BM2.Very clean ignition.Easy to disassemble and clean.

A snip from the instructions

During shooting condensation is created inside the suppressor, containing amongst others ammonia (mixture of burnt powder and water). Failure to remove the suppressor within a reasonable period of time after shooting will cause rust to form in the gun barrel. It is therefore practical to unscrew the suppressor after shooting on a range before packing the firearm for transport. When hunting the suppressor must be removed after the end of the hunt. Store the suppressor so that air can flow freely through it and dry it out, if suppressor is put away wet a white powdery build-up may occur on the baffles, in this case just wipe it off and wipe thin oil over the baffles. When the suppressor is dry it is advantageous to spray a little oil (aerosol) into the suppressor. In short, treat the suppressor as you would treat your rifle.

There if only I'd read the instructions might have to buy another so the missus can read them first, then set me a test. Thanks all
