Thread: Oceania Defence suppressors

The big bore can will be for 338 and is not designed yet. It will not be started til the QD is fully operational.

The second part of your question is complex and deserves a proper explanation.

I started out making cans without the benefit of sound testing gear. Once I had the gear and fine tuned what I wanted from a can, I set out to make world class cans. Suppressors that have the features that people want and will stack up to what is offered from the best manufacturers in US and EU. Many manufacturers have gotten so caught up in the mil spec testing that they made cans that are very quiet at the muzzle but fairly loud out the chamber right where your ear is. This does not matter as much with bolt gun cans as you really focus just on making the front end as quiet as possible since you will automatically pick up a 6 to 10 dB reduction at the ear. It is a much harder balancing act on a semi auto.

All design is a compromise but I will provide accurate data on my cans mainly so that the purchaser will be able to determine its usefulness as a safety device for hearing protection. My first 556 cans hit all my design goals of hearing safe at the ear as well as hearing safe at the muzzle (milspec) while being lightweight and very short for overhang. I have not changed the Samson model at all but have made continuous subtle improvements to the 556-45. By making a small change and metering the improvement, I implemented a list of baffle features that work better.

My last 556-45 is quieter than listed in my site due to these improvements. It is too heavy though, and too specific and as such is not going to be continued. The Samson is getting changed to fit all the rifles the original 556-45 was made for and still provide the smaller package but with improved sound at the expense of slightly more overhang from the muzzle. I have tried to keep these units in stock while testing and improving, but occasionally run out. My last batch of cans lasted a week. After this batch of Samson cans is tested, I will publish the data and stock up.

My first 30 cal cans were not as good as I would like them to be. They were hearing safe from a bolt gun at the ear but not good enough at the muzzle or at the chamber on a semi auto. They were very short but I have the ability to make them quieter. As such I have not stocked them on the web site but have been testing and improving them. The 300 BLK can is about ready to release again with very good specs for sub and super and acceptable levels of sound at the ear in 308 on a bolt gun for such a small can. The AR10 can will be out next and will have to deal with shorter barrels. I may not be able to get the sound down to hearing safe on sub 18" barrels at both chamber and muzzle without a lot of length.

Much of the baffle design improvements have come through intensive development of a pistol can. Once you get past the Neilsen device spring tension, all the focus was back into the baffle design which carries over into the other cans as well. After 17 iterations of design changes in different cans, it is ready to compete with the best in the world in sound at half the weight. It is the best compromise of length and sound to fill most user requirements. This can is in stock at one retailer who took all my first order and placed a follow up order. As such, it is not shown in stock in my site but will be next week with a variety of threads for the pistons.

As I get a feel for how much to stock of each can, I will be less likely to run out. However, retailers will always get stock before my site does if a model runs out.
