Thread: DPT Suppressor seized up

Some people can read a magazine while having a sh@t so maybe taking the suppressor next time and clean it, plenty of time there i guess😁

i use crc aerosol copper anti seize on the threaded parts, and wd40 specialist silicone on a rag on the outside and inside to clean never had a problem with any stuck sections

They already have a purpose built wrench, available at the shop, I’ve watched Nick use one.

I’m pretty sure it’s available for sale.

Always a good idea to follow the instructions that came with your suppressor:

Suppressor maintenance instructions - DPT Machinists

Having used them for years and been through this multiple times with my rough as mates, I can assure you the DPT will not seize if you do the basic preventative maintenance and don’t over tighten the baffles when reassembling. I watched one particular mate of mine, who is an enormous unit with hands like walrus flippers, carefully reassemble his suppressor after I had cleaned it for him, and then go to each individual baffle and give it a twist as if he was torquing up cylinder head bolts. Despite the threads having just been lubricated, I couldn’t get it undone again. Irritating! Old mate got it undone…. eventually.

You can always mention one of the guys directly and if they are around they will reply, usually.

However… I was in the shop of a well-known person in the trade last week, and I asked him why I hadn’t seen him around on the forum for ages. Very straightforward answer, he thinks the forum has been taken over by a bunch of whingeing anti-everything fuckwits who attract exactly the wrong kind of attention to all of us, at a difficult time. He named some names, some of whom were removed in recent weeks.

When I left the shop I was really annoyed, but fully understood where he’s coming from. I think it’s a great shame that the expertise of some of our innovative New Zealand guys is not as available to us in public forum as it used to be, for precisely the reasons that some of us have been going on about for bloody ages. No it wasn’t one of the DPT guys, but come to think of it I haven’t seen them around here for ages either.

Anyway. Rant over.

Maintain your suppressors!

This is my first modular suppressor and really happy with the performance and build quality.

@tikka how did you find it compared to the Oceania Defence can? Are you replacing the Oceania can with the dpt?

Back at work tomorrow.
Any body who has one of our suppressor stuck , we usually take it appart and service it at no charge. Juste bring it with you to the workshop.

Cheers.

Me two
I guess it's all very well using this and that but if the bloke that makes them tells you to do something to maintain it I'm picking he knows what he is talking about
I'm sure if DPT came up with a better solution than they already have then they would tell us,

@Friwi. Whats are good alternative to wd40. Innox, CRC, Break Away, All in One, gun oil......?
Can Gun cleaner be used to remove carbon build up?

You can use Inox if you do not have wd40. Avoid CRC 5.56 at all cost as we have found that its rust removing formula tend to degrade the finish of the suppressor over time.
There might be other alternatives out there, but frankly wd40 works very well and is available in pretty mush every supermarket in the country.

Both equally great in sound suppression in the 300 blackout supers and subs, both are top quality builds. The 3D printed titanium in the ODL makes them pricey for the average 20 rounds a year shooter.
No not replacing the ODL can, I only got it for my 300BLK and is coming up to 6000 rounds with zero issues and would get another if I built a custom rifle.
The DPT can is on the 308 and works perfect, I strip it down every 50 - 200 rounds, clean and re-lube the baffle threads, no problems for a $200 second hand suppressor. I haven’t had any alloy baffle wear yet with rapid 10+ rounds goats culling and has only done 800 rounds so far.

Here’s my stuck baffle removal kit, 2 hose clamps and rubber strips to grip and unmarked baffles. A few light taps from a hammer and free or unless your got the strength of 10 village idiots that will work too.

I'm gonna have to try again, I have 3 seized suppressors, the 4 newer ones are ok as I finally read the instructions that come with each one.

We cover the stainless baffles in white vinegar. The crud comes off and leaves it spotless. We use kero to clean the inside of other baffles with a rag and put Valprex grease on the threads when reassembling. We have both MK1 and MK2 cans. We have the DPT grips for both models.Shame not not use the proper gear if it is available.2C.

It’s the kiwi way to think out side the box to get it done on the cheap.

Must have learnt from the Scots!
