All three of mine have Dan Haga adapters to our ACR stocks on them. The pistol has the Dan Haga Tailhook adapter.

I think the ACR stock is far more comfortable that the stock CZ one.

I saw the ACR stock adapters, looked pretty nice! But I'd already ordered the other stuff.

Forgot to mention, if anyone has a gun with the trigger pack welded in, just contact CZ. They’ll send you a brand new lower. You don’t need to drill it out.
