NP - they are designed to be "taken down" for cleaning every time they are fired, if cleaned properly, thus they are designed that way.

I will also state that I take down my flintlocks (remove the barrel and lock every time I clean them, which is AFTER every time I shoot them. One has 3 pins and 2 screws holding everything together while the one with the 44" bl. has 4 pins and 3 screws as the lock is held on with 2 screws in this model of rifle. (lock screws plus the tank screw which screws from the tang into the trigger plate.

Many people do not take their long rifles apart for cleaning, but I (& my brother) maintain you cannot properly clean a muzzleloading rifle or smoothbore, without removing the barrel and lock from the stock.

With the long rifles, I leave the ram rod in the stock for extra support of this delicate part, when the barrel is removed.
Guns with hooked breeches are designed to easily be "taken apart" for cleaning. If this is necessary for storage, fine and dandy. Do not lose the barrel wedge. Many guns have a slotted & pinned wedge that is "captured" so it cannot be lost.
