This is how I flush after using corrosive ammo. It slides on the rinse hose in the kitchen sink and the other end is a clear plastic tube that fits in the chamber. I don't even have to remove the furniture because it is leak proof. Just hold the muzzle over a bucket and run hot water through it. It works very well. It even makes cleaning after the dirtiest ammo much easier. The metal dries almost instantly if it gets hot enough.
