Oceania defense suppressors

if its really quiet it would still be ideal for the pest control guys working from a truck where weight doesnt matter...

I think that as long as minimum suppression required is met I would consider length forward, and weight and to a lesser extent durability as the next items of concern.

This is right, people try and make overbarrel, but then there is not much gained by behind the barrel. The weight thing is not such a big deal if shoot from a bipod, but trying traditional shooting positions that weight on the end could cause problems with hard to stop rifle wavering all over place.

Missed getting a shot in on some decent reds years ago. Had a heavy barrel Rem 308 with MAE on the end. Thought was good suppressor. Was spring one year and grass was quite long. Spied some deer and had to get into a sitting position to get a shot in above grass, couldn't stop the rifle waving around. Didn't shoot and figured it out when got home. Tried rifle with on, with off.
Balanced nice off, but on just kept fighting it as centre of balance had moved so far out. Changed to a DPT, wasn't as quiet but got balance back.

Got some nice Jacindabucks for the MAE when that opportunity came along.

Is interesting but materials always been cheap labor and R and D are expensive if you make it in NZ.

Might considering it's over 10inchs muzzle forward and half a killo hanging of the end of a rifle even in a short 16 inch AR it's equivalent to a 26 inch barrel.

The other thing people don't consider is that one factor is that actual volume added to the blast chamber by the overbarrel part is quite low as the isolation tube removes that extra volume to fit the barrel and usually its not optimized for volume more so the ability to fit a wide range of barrel contours. Plus having to add a second tube adds weight for little gain. It's a bit of a nessarry evil sometimes but it's not efficient weightwise. Could be more effective it the isolation tube was removes and rear sealed to barrel or if the iso tube size was minimized. The kimbers quite light so even a 300gram suppressor changes the feel alot.

If you compare anything made in China its going to be significantly cheaper, there costs/ materials/ labour/ contractors/ etc are far far lower than ours. Look at the price of a Chinese firearm and compare it to something made in Europe.

I wish it would only cost us $90 to produce a centerfire suppressor.

It is not quite market ready but the pricing gives an idea of what suppressors are really worth. The mono core is actually much quieter than baffles which surprised me. The gas / smoke is trapped very well and is much slower to exit after a shot. I guess what i am trying to explain is that the gas retention is better with this monocore, possibly because it spins the gas to the outside and cycles it back directing gas flows against each other to cancel sound

Any pics? Be cool to have a budget option in nz

I would love to be able to post pics to the forum again but windows 10 has stopped the download camera option and the new phone ( samsung galaxy) wont do it, new tech has disabled everything for me

The early Greystone suppressors sealed on the barrel without an isolator. This was a disaster with the CO2 and water vapor forming carbonic acid and literally eating right through a barrel down to the rifling lands.

The full overbarrel suppressor and ported barrel is probably the best option for shortness
With the 285 mm suppressor on the break open gun, overall length is still only what an unsuppressed bolt action is, so I can live with it but totally agree that a shorter one would be better. The gunsmith who designed it and threaded the barrel told me that for subs a long slim suppressor is superior to a shorter fatter one even if the latter has greater capacity.

I've got the 762 QD ODL can. I've shot it on a 308 and used a Hardy Stealth on the same rifle after. I personally found the ODL suppressed better but it does have a noticeable first round pop.

I tried it hunting but I just didn't like how much muzzle forward it was, I've ended up using a DPT which I think is a better option for hunting. The weight difference isn't that much with the ODL brake included in the weight.

Positives with the ODL are the fact the QD system means it won't come loose, very quiet and strong for the weight and it can take a high rate of fire.

I mainly see its use in NZ on a PRS rifle or something that needs a muzzle forward like a lever gun.

Personally I'm not a fan. They are 3-4 times the price of a good alloy over barrel, they are no quieter than any other suppressor and IMO (and Hardy's) the DPT and Hardy are quieter. They are not actually that light, titanium is a heavier material than the alloy used by dpt and Hardy and if all things were equal wit the Oceania muzzle cans eg diameter and length/internal volume etc they would actually be much heavier.
They are strong where it counts and can cope with sustained full auto for which is why they have been tested by over seas defence agencies but that is of no use to us.
The reason they dont make a larger over barrel unit is mostly because of the cost of printing it.
While the tech is cool I'm not a fan of the gritty finish and the odd looking raised twist patern on the outside of the can. It just looks wrong.
The price tag doesnt reflect a 3x better suppressor than others so I for one will continue to use DPTs and Hardies.

We swear our MKll 243 magnum is quieter than our MK1 223 with 7 baffles. Plus o/b. Whats not to like. New DPT MKll. LOL.

Yes, the QD is a bloody good system but the addition of the muzzle break does add a bit and is a bit longer than say an alpine. I would go back another 2 inches on rifles that I want to balance correctly with this system. Like you said for PRS Bipod shooting doesn't matter...

It's just a continual quest for right calibre, right barrel contour/length, right scope, bipod, suppressor combo holy-grail.....then what do you do, fun trying to find it?

@Seventenths ... any change in point of impact when you removed baffles?

@Maxx I honestly can’t remember if there was a point of impact change as we were just testing the sound.

I’m hoping to be at the range in next week or two, will test the POI with removal of a baffle ��

I havent noticed any shift in POI with different numbers of baffles on my DPT
I vary between 4 and tons more when I feel like it so I suspect you wont be able to tell the difference

Thanks guys....
