Thank for any help
I've tried a couple different flush kits...one that clamps over the vent, another that screws into the vent seat.
The one that screwed into the vent seat worked better but if you can't/don't want to remove your vent, then that's out...(not sure I understand why it can't come out though).
The clamp type never seems to be 100% leak proof for me, but I found laying the ML on its side in one of those Outers Gun Cleaning cradles at least let the drop(s) fall straight down away from the mortise;
But...even knowing I have to be extremely careful with removing/cleaning/reinstalling a barrel due to risk of marring the stock, it is without a doubt the quickest, simplist, and most satisfying to me in terms on 'knowing' that bore & breech are 100% squeaky clean, dried, and lubed...and the exterior is maintained completely clean/lubed/rust free as well.
Carpeted, waist high work bench is extremely helpful, just 3-4 pins depending, and a tang screw...reverse very slow and very carefully. Have done each of 3 Flintlocks that way about a dozen times each and haven't noticed any loose pins, stock damage, yet...so far, so good.
