DPT Suppressor tight baffles

Team, I have a DPT over barrel suppressor with modular baffles. Very good unit and Im getting another one put on the 7-08 now.
Maybe I should ask Darren first but my baffle stack has two units pretty much stuck together and the first baffle also won't come off the main section.
Anyone have the same problem?
I don't want to put it in a vice or similar as the walls are not very heavy and I don't want an oval baffle.
I did try a little bit of heat without success and was thinking a soak in something may be the fix?

I have one the same. Stuck baffles.
The last one I got had instructions about grease and how to keep them freed up, but it was a bit late.

Same here. I dont care though. I'll shoot it out till its buggered and buy another one. That'll be a while yet I'm sure I'll get my $300 worth :)

Anti seize is a wonderful thing.

I would try boiling the thing then with gloves submerg the male part only in ice water and try and undo by hand.
failing that i would not recommend any other method to someone who is not me :D

that way you should get enough expansion,contraction without enough heat to damage anything.

as a fridge dude you would have access to liquid freon ;)

They stick with carbon buildup and occasionally wet carbon that liquified then dries in the threads similar to black loctite :)


The trick is to disassemble regularly and clean and grease properly.

If stuck I can imagine soaking in diesel/kero mix for a week should soften the carbon, and won't harm the anodising.

I think you'll find the first baffle that won't come undone from the main section is in fact the module containing the threaded section, and is loctited to the main chamber. Have a close look inside with the other modules off. Unless you're meaning the next one along of course..

My modular can is all fused up too - so now with my more recent overbarrel, I just unscrew each of the modules a few turns of the thread when storing. Only takes a couple of seconds to get it ready to go again.

Is there any particular reason why these cans are modular? Just interested

I have the same thing with mine its been used twice the 1st time I went to take it apart to clean the threads as I don't want not to be able to take it apart. and found 2 had stuck together wasn't worried too much though 2nd time I used it I noticed another 2 were stuck together so now I have 4 of the 5 stuck together
this is after less than 20 rounds.... ive very carefully tried a soft jaw vice to grip one baffle while using hand pressure to undo but no luck...

however that being said they are a very good unit and work extremely well mines quite fine to shoot with out muffs and is way quieter than some other way more pricey ones I've owned/used so very happy with the dpt (apart from this relatively minor issue )

its so you can remove/add baffles so you could remove 2 of the 5 baffles and sacrifice a little quietness but have a shorter suppressor or buy an extra baffle or 2 and add them to make it even quieter but make it a little longer it just makes things a little more customizable for your needs

As 7mmsaum suggested, soak them. Brakeleen?

Dealt to it.
Shear horse power from the hands department got one apart ;) and a strap wrench dealt to the other.
Still got the cap on the forward unit but meh, not worried there.

dpt lock tights that on its not ment to be taken off says that on the info sheet you get with your can:)

just managed to get mine apart as well got my brother onto it who is a lot stronger than me he managed to take them apart by hand

They will come undone with some muscle. I take mine apart regularly as I switch between 6.5 and 308 barrels

Anti sieze or grease on the threads

Carbon will build up inside where they screw together whuch may explain the tightness. Like everything elee look after your gear. Mine hasvprob 200 riunds through it so far

Ive had mine a couple weeks an over barrel on a 243, Just a bit of brute hand strength to get it all apart. The end cap and module are Loctite and the first baffle with the thread has Loctite as well. The instruction sheet explains the care and cleaning etc. I just loosen the baffles a bit by hand and tighten again after firing and will do the first clean as per instructions.

Mine is a different brand but two of the modules were tight together when I got it. Gunsmith said he thought they were loctited but I had a go next day when I was feeling stronger and they came apart with bare dry hands - no loctite in threads that I could see.

Now I use a lithium grease between them and dismantle after most uses. Once got quite a bit of rainwater inside it carrying over my shoulder in spring weather. Green powder inside as if vapourised copper was mixed with the powder residue. No problems taking it apart at all.

I reckon the suppressor, all its joints and attachment to the barrel is a key precision fit area of your rifle like scope mounts or bedding so try and keep them all clean no grit, no dings on the muzzle thread, modules snug and in same order. I only use 2/4 modules; suppressor is short and light and still does the job - no ringing shooting without protection. Real good.

I clean mine and grease as per the instructions after around 25 shots.
Comes apart real easy.
