I have a custome 54 if you are interested . Just got a full knee transplant so I am going to be running on 2 cylinders for awhile . PM me and I will send my cell if interestedIv been eyeing up the investarms gremmer either in kit or complete but on muzzle loader.com they have in left handed and in different calibers, .50 and .54 I believe. From what I can see it’s a nice rifle for the price, Italian company but from my understanding not pedersoli. That’s an option and in .54 whoohooo you can’t go wrong!
