Re: 10/22 Barrel
Ok, I'll give it a whack....
The YHM is not an integral, it is nothing more than what we call a "dedicated can." All they have done is take a standard barrel, cut it back (and not enough to insure subsonic speeds) added a monolithic baffel set and stuffed it all inside a hollow baffle sleeve.
It does not in any way meet the criteria of integral because as we know, an integral sole purpose is to tap gas to insure that a specific bullet is always delivered to the core at subsonic speed. Why is that important? Because the only way one can insure maximum supression values, both the blast as well as the flight signature of the projectile must be attended to. In other words, the YHM is loud, as loud as any supersonic rifle with just a blast can on it shooting supersonics. It is a dedicated blast can rifle. Same for the aluminum barreled, dedicated unit mentioned by ddd above.
Now the Bowers does tap gas, but it too does so with a monolithic stack that is removeable. Whereas it is much quieter in all regards to a dedicated can shooting any supersonic cartridges it has a limitation due to the diameter of its envelope. Because the Bower system utilizes a barrel diameter that fits within a standard Bull Barrel Ruger stock it cannot tap gas and divert a high pressure stream to precharge the stack prior to the arrival of the projectile to that stack. That means that the Bower unit too has some very real limitations.
You can do better than either unit by remembering these simple thoughts:
Integrals tap gas to take a perscribed projectile to a speed that represents the highest possible subsonic velocity. That means maximum suppression while:
1. Maximum Range
2. Maximum Terminal Force
3. Maximum purge pressures
4. Maximum ammo costs efficiencies (subsonics are expensive)
5. The use of plated rounds is made possible (no subsonic has figured out that if you plate the round leading is reduced to the point where seal stacks become practical.)
6. Precharging can be made possible, removing a degree of frp and increasing fr accuracy.
7. And lastly, but most importantly, the envelope can be placed under considerable compression. That makes the barrel significantly more accurate than a standard barrel.
If fact, if you spend the bucks to have an integral and you don't get the qualitites listed above, you are missing out. The Op asked about a true integral, the AAC unit a gas tapper as well. I was just curious why you thought that tapping gas "sucked" as I have yet to see an integral that doesn't.
An integral in .22 represents the quietest and most accurate suppressed rifles currently available. Folks just need to have some sense as to why they cost what they do.
That would be my spin on it.
