Thanks everyone for the advice.
I’ve messaged the seller (friend of the family) that I want the rifle and have cash in hand.
Now I need to buy some .54 RB and flintlock accessories. I’ve only shot percussion in the past.
Thanks all for the information.
I would use the rifle for target shooting (paper/steel). I know I don’t need a .54 for that but I can buy the rifle for $400 and it’s like new. I see the retail price online is $729...
