Re: Integral suppressor accuracy question. ???
BenY, the answer to your question requires a fairly deep and broad review of the rifle shown in your photos. In doing so, you can only get a small part of your question answered as to accuracy for this design, as it would take a close examination to really know for sure.
There are few supressor designs that will perform as remarkably as an integral. When properly prepared they rival the very best possible in regard to accuracy, suppression and sheer technology poured into a single host. But that comes with very real limitations, mostly driven by cartridge selection and caliber as integrals, by design, make most sense as strictly subsonic platforms. For reasons we can go into if you wish, they also are pretty much deligated to small caliber (majority are by far rim fires) as well. In fact, I would go as far as to say that if one's intent is to shoot supersonic rimfire, an integral makes for a poor choice over blast can designs. And that is where we have to begin.
The great advantage of integral designs are their ability to acheive the highest subsonic velocity uniformity and therefor, the longest possible range, highest terminal force and best chance for consistant accuracy. This is acheived by "tuning" a properly prepared integral by taking a quality supersonic cartridge and bleeding off pressure to drop the velocity to transonic levels. There is a great deal to be said of the advantageous found in REDUCING supersonic velocities down to a uniform subsonic velocity over INCREASING subsonic cartridge velocities to acheive transonic envelopes tailored for every action/barrel/suppressor. Perhaps even more importantly, the current production of subsonic cartridges are uniformly filthy by way of powder choise (read this as cheap crap), and the bullets are not plated (an important feature especially in integrals) to greatly reduce leading. Its the tuning, the PROPER tuning of an integral that allows for maximum performance. The best are built around a fairly well defined supersonic cartridge or family of cartridges whose velocity is specifically tuned so that what comes out of the end cap is as fast, stabile and clean as possible. Gone are the days of "swiss cheese" ports, this is all done with a single port, properly placed. But there is more, that port and its potential to path supersonic gas to "precharge" a target chamber makes for the potential to eliminate, as best as possible, FRP. So, before we even talk about the accuracy of the barrel, the appropriate design and execution of the stack, its purge and heat pathing, the precharge" we spoke of above, or the means to properly compress that barrel, we had to cover velocity.
So, where are we with the rifle we see a link to? Well, unfortunatley, that is not an integral design at all. It is a "dedicated" stack with a compression envelope. It does not tap gas, to does not reduce velocity, it is just a can stuck on the end of a barrel with the potential of some improved barrel whip characteristics due to a poorly executed compression sleeve. Many really can't even tell the difference, makers, it seems, included. Could it have been more? Sure, it could have used the outer tube as the intitial chamber, ala a "reflex" like the Aries design (also a "dedicated" design. But, a close examination of the first chamber shows no gas deflector. The first clue? No gas tap, the second? No ported diverter with redirects in the stack, the third? the length of the barrel. Compression in this platform is not complicated...until you add the right precharge path.

This maker, to my mind, could do much better, and you can too. There is a ton more on this subject, but I am not sure anybody even reads responses this long anyway. Best.
