Thread: Oceania defense suppressors

Hey team. I was at the Sika Show and saw these suppressors up close at the Glacier Rifle Stand. I had a chat to Jed who from my understanding is one of the engineers at GRC. I think they supply certain parts for the OD suppressor.

I was very impressed with his rundown on the suppressor however I don't seem to hear much about them. Not many threads about them either.

Does anyone run these on a magnum? I'm looking at one for a 20" 6.5prc. Just looking for pros and cons. (One con obviously being the cost)

Yeah there are threads on here, in my opinion best suppressor you can buy in NZ, overseas people are very impressed as a number of foreign Special Forces have trialed them.

Only thing is they are a bit more expensive than other NZ made ones but on a par or cheaper than overseas top of the line ones.

Why I like them is they give your rifle back it's balance for freehand shooting.

I just run an m14 Thread Oceania Alpine 30 cal on 270, run my old black rifle 556 Samson on my 22.250. Also have a 30 cal rachet/brake one that can quickly pop on my 22 Creedmore, 6.5 Creedmore or 308.Also have a 9mm pistol one use on a glock.

Cracks me up, my 22.250 Ruger cost 700 bucks with a set of dies, sports a 9 hundy suppressor, 3-15 Vx5 and javelin bipod, great wee rifle though!

270 is using about 57 grains of Super-performance powder with the Alpine model, I reckon you would get away with it on 6.5 PRC if you want super-light and compact? If you want greater noise reduction could go up to a magnum, bit more expensive.

I'm wanting my 6.5 as light as possible yep. I'm not shooting often, I'd be lucky to take 1 shot on a trip. I was hoping to run a non magnum but thought there may be some issues with that? What issues could arise if I ran a non magnum version? @jackson21

Maybe give them a call? But my thoughts are whilst it's called a magnum if you can run cartridges with simular powder weight I wouldn't think it's an issue as surely it's same pressures etc?

I was bit nervous running my 22.250 through my 556 one but seems fine, probably put 600 rounds of 22.250 through it, probably 2500 rounds of 5.56 before that.

Will do. I've tried calling a couple of times but haven't got through. Makes sense though, cheers for feedback

I would, but I don't want to be giving you advice above my pay grade. I was going to run it on my 6.5 x 284 which is simular to a prc but decided to just leave as was with longer barrel un-suppressed.

I think when they mean Magnum it's like 7mm, 300 WinMag with large case capacity, and then they do a 338 Lap as well.

I have an oceania defence alpine on my 30/06. I really rate it

Best suppressor money can buy

good units, recommend

Lighter is better

Their muzzle foward right?

Not all of them.

They are now.. all the new ones are muzzle forward.
I cant keep up with them.. they seem to constantly be changing them and developing something "better".
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.

When I bought mine they were not even twice what a Hardy was, actually my first one was only a couple of hundred dollars more than a Hardy at the time as someone had used it as a demo.

Maybe they have gone up in price and Hardies down? I'm guessing you probably shoot from a bipod? If your are trying to shoot unsupported that extra weight saving not on end of barrel I find a massive difference to being able to hold steady.

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.
