Hey guys, there are a lot of good observations in this thread, especially by John A. and I thought I would go over the design of the Venom Suppressor to explain in a little more detail.
For those that don't know, I am Sven at Manticore Arms, and I designed the Venom Suppressor.
The goal of the project and the design was to make a suppressor with the shortest added length and largest overall volume without requiring "permanent" modifications to the gun ( i.e. drilled barrel or anything that caused it to not be able to be fired without the suppressor core installed), and that was easily installed, serviceable, and removable by the end user, and that was at a price point we felt was reasonable in comparison to the base cost of the scorpion.
The suppressor core does sleeve over the barrel (or rather the muzzle device) a bit. This accomplishes two things in one use- first it acts as the alignment system between the bore and the suppressor core to keep everyting co-centric, and second it acts as additional valume. The reason it does not sleeve father back is the weight per volume gained started to go up substantially, and the core itself is designed to a length the will work on a shorter forend for the Micro EVO that will be a follow up release.
The muzzle device itself is what takes the brunt of the particulate and initial blast from uncorking- it is essentially the blast baffle you see on other suppressors.
The only purpose of a ported barrel is to keep your bullet velocity down to (theoretically) subsonic levels, but with the vast availability of heavier and subsonic rounds today, I personally do not think that there is a lot of added advantage to the extra cost, complexity, and one way direction of drilling the barrel to make all rounds subsonic. With a standard barrel you can run subsonic if you want it quiet, and run the hottest rounds you want for more hitting power downrange. Either way the suppressor will still reduce the sound even if you have a supersonic crack. If you want to get a ported barrel setup there are options out there, my personal take is non-ported is the way to go.
As to how we can slide a core into the forend and not have gas leakage at the interface of the two surfaces- the fitment is carefully toleranced, but more to the point the gas goes where it is easiest to flow- out the bore hole. This concept was tested and proven out in the earlier ZRX suppressor for the Tavor SAR 9mm which Ratworx put out about 5 years ago, and the simple truth is even if there was a tiny amount of gas leakage at the interface....it doesn't affect anything. The gas is still contained and released slowly as it cools.
