Rynite Synthetic stock from a Thompson Center Grey Hawk percussion muzzleloading rifle with complete lock assembly and wedge. Never fired, in very good condition, showing no wear! Hammer was never dropped on a cap. I am not sure, but this may also fit the New Englander series barrels that are 15/16 inch diameter round barrel and use a single wedge. Please be sure this is an item you want before placing a bid. If necessary, ask questions or request additional pictures. Please check my other auction listings, on multiple purchases I will combine shipping costs whenever possible. NO SHIPPING OUT OF THE U.S.A.
