Thread: DPT Baffle Corrosion

after a week long trip i cleaned the rifle and at the same time thought i'd have a look in the baffles of a 6 month old DPT magnum suppressor. I was surprised to see a significant amount of corrosion and build up in the first couple of baffles in particular, but noticeable on all baffles. i gave them a clean/scrape and it has quite noticeably eaten away at the aluminium of the baffle. i've fired max 30 rounds of 7RM through the suppressor - is this normal?

i know they only have a limited shelf life, but at this rate it looks like it will be well shot by the time i get anywhere near a couple of hundred rounds (perhaps this is the brilliance of the relatively affordable DPT replaceable baffle system???)

so should i be looking after it differently? e.g. open the suppressor after using it and clean with solvent - or similar??


also have a Hardy Gen V and a Gunworks for other rifles and it makes we wonder what is going on in their internal organs...

Hmmm. Maybe you need to ask @DPT

Id be asking the man who makes them, probably knows about them a lot more than others.

Aaargh.
Don't use solvent. Use the instructions DPT gives you with the suppressor.
Clean with warm water, dishwashing liquid and a soft brush/cloth and grease the gaskets when dry and reassembling.

Get the additional steel baffle from his website if you are worried about life span.

I use my sonic cleaner with simple green to clean carbon and stuff off parts. Works a treat. Just need to protect said parts properly after doing so.

Get hold of Darren. He is great to deal with and will sort any issue you have.

I have had him go over one of my suppressors and he cleaned it up and returned it with an extra baffle I wanted within a week.

thanks guys, i don't recall seeing the instructions but may have tossed them as i have an aversion to anything printed on paper. will clean it the way you describe

its not a major issue yet, but the first baffle will be quite corroded by the time another 6 months comes around.

seeing this is a good reminder to NEVER leave a bloody can on the end of the barrel to eat away at the crown...

Do you have a picture?

Crickey, I haven't touched my DPT for ages as I can't unscrew the baffles (utterly buggered shoulder). Shot close to 1,000 223 rounds through it, I just figured it was like the Everready battery, just keeps going and going and going

I had fairly bad corrosion in my .17hornet after about 400 rounds, gun since sold, but Darren PM"ed me re the damage, Contact him direct, SS baffle I think helps

Yes 17 hornets are very hard on cans apparently & S steel baffles are best. That reminds me to open it up and have a gander Maca

Hi,

Corrosion inside the suppressor is caused by moisture mixing with the burnt gunpowder, this creates ammonia, the obvious sign of this is a white powdery buildup. After every use the suppressor needs to be left in a place/ position that will promote it to dry out, this point his highly stressed in the instructions that is supplied with every suppressor we sell.

Thats one trade off with ultra light suppressors is they need more care and attention.

If you email me some photos through id be happy to take a look and give you my opinion sales@dpt.co.nz

Quite a few of us never see the instructions as the supressor goes directly to the gunsmith and all we get/are interested in is picking it up fitted and ready to go. Had this concern with mine and you set me straight over the phone, but maybe posting the maimtenance instructions here might be usefull.

I've got a pdf of the instructions.
Anyone know how to post onto here?

post some pics of the baffles.. id like to see as im sure everyone else does

I would like to see these instructions as mine definately didnt come with any, it also has quite noticeable corrosion on the first baffle after only 30 rounds of 270 wsm, suppresor is only a week old.
