in the case of the traditions kits (spain) they can be hit or miss with regards to parts fitting, but mostly missing and requiring some thinking, improvising, and labor. you do what you gotta do to make it all work reasonably well. after building a dozen or so of different offshore trad ML kit guns, the investarms (rebranded as lyman, DGW, cabelas, etc) are a bit better on the build, specifically because their breech plugs can easily be pulled with proper tools. not so with the spanish guns where their plugs almost seem to be welded on and traditions specifies attempting to pull plugs is tantamount to destroying the gun.
almost all the offshore trad ML kits will sport those patent ante-chamber breeches (that require special attention for fouling control and cleaning), and none of these guns will have much in common with real 18th century firearms, if that even matters to most folks. they all kinda look right from that era, but in reality, nope. doesn't mean that's bad or good as most folks just want them to work and that's where the flintlock versions can be Very hit or miss as lock geometry and parts are typically not that much up to par.
so, it can be kinda important to understand just what yer buying with regards to both the offshore trad ML kits and completed guns. some or a lot of that understanding will lean on yer technical ability and tooling to make "adjustments" both with their build and their shooting. they is what they is, and they can all usually be made to work from reasonably well to extremely well with understanding and time at the least.
