Thread: Blown suppressor baffle - Launched 20m downrange

Do not use copper antiseize on an aluminum suppressor or an aluminum anything.
The two react.

Off topic. Beats Kroil? Bookmarked that.

does it cause galvanic corrosion?

Yes to galvanic reaction r

Yes togalvanic reaction

The problem here is the 6mm creedmoor. If it was a good old 243 would never have happened……��

I just use silicon grease on mine and loosen the baffles off when im finished using it

I resemble this remark lol. Heard the story about the aftermath of cleaning one with petrol - kaboom!! Often wondered why WD40 or the CRC I use doesn't do the same. I'm doing load dev at the moment with my shorty 1915 SMLE with a DPT Muzzle forward can. The first four shots I last tried at 50m were near max charge for cast bullets.. only one hit paper. There were clouds of smoke out of my newly cleaned DPT - hard to tell if it was leftover CRC (I was liberal as last shot in moist conditions) or vaporized lead or disintegrated powder coat. Anyhow, back to the range today to try again with diff projectiles starting low. One interesting observation with this particular setup, I shoot the first two of a load without suppressor to check they are leaving the barrel pointy end first, then add the can. Immediately the POI moves up a couple of inches or three, at 50m.

Back to topic, I've been using DPT on several rifles for some years. Also have Gunworks and ASE (could only afford one). I happen to clean them and keep off the rifles when not in use. No issues to date. Would certainly buy another.

Hello Roarless,

I am sorry you have not had satisfactory aftersales service from us, it is definitely not the way we want our customers to feel.

We did try to call you back multiple times but for whatever reason the calls did not go through, so just on closing we emailed you. The reason for the straight to the point reply by email was, I could identify with reasonable confidence (from the photos you sent me) that this failure was caused by corrosion. This failure is not a faulty product or faulty material related failure. The reason I came to this conclusion with my first assessment of the failure, is we have 50,000 ish suppressors out there and we have seen plenty of failures relating to misuse, from suppressors being plugged with material, suppressors not being screwed on, bullet strikes, etc etc, As well as corrosion. During our product development we have put the suppressors through some pretty hard failure testing and seen how the material fails. Failures caused by fatigue or the alloy being put over its rated strength, breaks differently to corrosion related breaks, it fractures differently and is very obvious for me to identify. We would have loved to have gotten the damaged baffle back to look over it and definitively confirm the cause of failure, but given it had already been machined out in your lathe that is not possible.

With the hopes of moving forward, please send the suppressor back to us, we will disassemble it, clean it and go over it to make sure it is sound. Also feel free to send back any other dpt suppressors you have, at the same time and we will do the same to them.

As a side note to all the other readers, we have always offered a free suppressor disassembly service, feel free to come in if you have a suppressor with stuck baffles and we will sort it out.

Cheers
Darren

On a more merry note, a bazooka.

Short range at that

you cannot ask for better service than that...good on you Darren.

@DPT Hi Darren,
Thank you for this reasoned explanation and offer.
Its a pity the calls wouldn't go through after the first call to me working. This is the sort of response I was expecting to hear from you on the phone.
It's too close to my planned hunting trips to risk sending my suppressors up to your team. I'll look at doing so after all my Roar trips are finished early May.

Regards

Grease the O ring and threads with lithium grease before re-assembly.

Hello Roarless,

Not a problem. If we don't hear from you within 6 weeks I will flick you an email as a reminder.

Cheers
