Always dreamed about an MP5sd, the integrally suppressed MP5. Just sick. but they cost like $7k now

Then I moved to dreaming about an SP5k, the modern version of the short MP5. Obviously I would suppress it.

Now the B&T ACP9 and ACP9k have been getting a lot of love

Then I just discovered the integrally suppressed ACP9k Pro SD - wow

https://bt-usa.com/products/apc9k-sd2/

this thing has a built in suppressor, and you can use regular ammo and it slows the bullet down so all of it is sub sonic (the MP5sd does this too). A regular PCC with a suppressor does not do this.

Thoughts? The ACP9k Pro SD might be the winner, and it costs less than an SP5k with an extra suppressor.

I would get a Noveske Space Invader or Space Baby if you insist on PCC. Otherwise I’d get their Ghetto Blaster.

Though the B&Ts do seem pretty sweet too

This is purely a function of barrel length. Short bbl, less time for powder to burn.

AP5 is by MKE, Turkish import, manufactured on HK licensed tooling. Well reviewed. There are three sizes. The LE is the full size (AP5-P) with a 1/2x28 thread instead of the tri lug and is like $850. Form 4 it and red locktite a cheap thread on tri lug and you’ll be john McLain for under 2 Gs.

It has something that apparently the mp5sd called a ported barrel that supposedly does slow down regular ammo to sub sonic velocity. Then it has an integrated suppressor. It's more than barrel length.

I'm aware of the AP5 and other brands, in addition to the new MAC 5k ones that are also made with the same machinery as the mp5
