Dpt suppressor

Hi Team so I got a 223 & 7.62x39 threaded I was hoping to get a 15x1 Thread on them as 2 other rifles have that thread so I figured the same A-tec suppressor could be used on all 4 rifles however the 2 barrels on these two where seemly a bit slim for the 15x1 so long story short I purchased a 30cal Dpt mk2 it has 5 baffles , went for a shoot up yesterday to sight the guns in & test the suppressor out , first shot with the 223 & I immediately regretted leaving the ear muffs behind , a quick swap to the 7.62 was no different , yes it was substantially better than no suppressor but still quite a crack .
When I run the A-tec on a 308 & 22-250 it’s vastly quieter so it got me thinking...how many baffles are you guys / gals running on your Dpt ?

Chur .

5 works fine for me, with magnums I run an extra ss baffle ahead of the aluminium ones

Where did you get the stainless baffle ? , I think I will get another one and put it on see if 6 tames that crack a bit more , I haven’t had a lot of experience with suppressors I kind of assumed they would be much of a muchness but perhaps not .

dpt sell them online

Here we go , a lot of reading in there but looks like page 2 the first blue graph gives the decibel reduction, the A tec I have is a 119 hertz so not on there but still makes for an interesting read https://d347awuzx0kdse.cloudfront.ne...b01d144f6995df

Interesting, according to the graph 4 Dpt baffles is slightly quieter than 5 but 9 is the biggest reduction....& the mark 2 Dpt being recently developed is not on there either , bloody typical I find some good info but it doesn’t include either of my suppressors!!! .

It’s a trade off between size, weight and noise reduction, cos physics. Small and light = louder, big and heavy = quieter.

I think DPT has the balance about right, but still need ear defence on the range. I think that’s a good idea for any moderators to be fair.

That link is well worth a read ...another thing I noticed about the Dpt & the A-tec was the heat , the Dpt seemed a lot cooler even after 10 shots in Farley quick succession , I just weighed the 2 , A tec 349 grams
Dpt 289 grams , be interesting to put the extra baffling on & weigh it , mate has a Dpt 30 cal but don’t think it’s a mark 2.

I run 5 baffles in the DPT on my 14.5" .223 over the dog with no drama. Loaded pretty hot with H335 as well and plenty of blast on the first baffle but don't think it's noisy. Use it for pest control as well near houses and on farms and never had any complaints after slaughtering a few dozen rabbits in a row.

Run 4 baffles including one SS in the 16" 6.5 Creedmoor and again it's surprisingly quiet.

Out of interest @Boaraxa, were you shooting with any kind of surface adjacent to you, so that can reflect the sound back to you? I have found that shooting several different types of suppressor is unbearably loud when there is sound reflection involved. Really gets to me. Open country, no problem at all.

Was your A-Tec experiences in the same place / conditions as the DPT experience?

Mines at 374g on the 22-250, just added 2 extra baffles coupla weeks ago. I can shoot this with no ear protection easy, kids dont mind either.

@Flyblown the first session was at the foot of a hill but I wasn’t overly happy with that location due to livestock so shifted to a large bank further down the paddock at both locations was the same sharp crack , iv shot the A-tec heaps in all manor of locations and never felt the need for hearing protection I think I’ll just get a couple of extra baffles and be done with it had I known there would be a difference I would have done a bit more research or got the gun smith to Wack an inch off the barrel,s to allow for the 15x1 thread .

The dpt over barrel with 4 baffles is 285 grams, you are probably counting the part that threads onto the barrel as a baffle, its not, the baffles have a caliber engraved on them. The baffles are 25 grams each, so an over barrel with 5 baffles should be around 310 grams.
Our muzzle forward that comes standard with 5 baffles is about 200 grams and is slightly louder than the 4 baffle over barrel (as you have seen in the magazine)

The advantage with the over barrel is that it doesn’t make the rifle as long as a muzzle forward.

We feel we have come up with a good compromise between weight/length/forward length/and price. With the flexibility to add more baffles to suit your individual requirements.

Happy to answer any questions you have :)

Not knocking the product as mentioned I figured these things where all pretty similar, it’s got more features than the Atec , I like how it comes apart easy & more baffles can be used so that’s what I’ll do , will be interesting to see what it’s like with a couple more on there .
@DPT To me it looks like 5 baffles ?

No worries :thumbsup:
Thats four baffles, the first one with the thread engraved on it is not a baffle.

I noticed a big difference in sound when I replaced the first baffle in my DPT with a S.S one and added a neoprene suppressor cover.

First baffle or the baffle immediately over the muzzle? We are experimenting with 2 SS baffles on the 223 MK 1 can which my son says is quieter than only 1 SS. Once we have sorted that out due to get 2 new MK 2 cans on a WSSM and 243. My son has a mate who is running 3 SS on a chopped 308 which he says is wickedly quiet.

The first baffle past the threaded section i.e as a blast baffle.

I really cant work this out...Ive had a mk1 with 4 baffles ,over barrel, on my poohseventy for 3 years and find it fine...tried it today on mates 25/06 and its rather tame indeed... we might add a S/S baffle to make it last longer but its quiet enough as it is....it compares well with either of the gunworks spartans I run...

I like my Dpt's my 300blk has 12 baffles on it for subsonic goodness
I rob my other suppressors as needed for baffles
Then swap them back for supersonic use
