The flintlocks are flinteaters, hard to get replacement parts and then also expensive.
The guns are muzzle heavy and flintlocks are just modified percussion breeches with a touchhole liner drilled in from the side. The flintlock rifle I had was from the 1990ies but the breech was so narrow it always gunked up after the first shot and nearly mad me quit the sport. The barrels are ok, but are shallow button rifled, not deep cut rifling. Nothing is done and fastened the correct way (pins), the barrel fastens with short screws through the ramrod thimbles to a threaded nderlug on the bottom of the barrel.These screws also hold the ramrod thimbles. Trigger guard is bolted to the trigger assembly on the front and srewed on the back with a "thin" and short wood screw.
My recommendation: Get a rifle from Tip Curtis made from quality american parts and you will have much more fun and less grief in the longrun. Especially the chambers flintlocks are so much better when it comes to flint life. I get 80 shots out of a flint or better. With my Pedersoli lock maybe 30-35.
A quality flintlock can simply not be produced for the price they offer them in retail over here. Essentially the gun is sold to the merchant for 50% of the retail price or less.
How many Pedersolis do you see on the primitive range in Friendship,IN? Maybe a few percussions but never a flintlock.
