I am looking at the J34 and the J107 Dragonfly.I have a 300 Rum with a Manners stock T5a.The rifle is 50"1/2 long with a Nightforce scope.My question is will it fit in the scabbards ok or will they be to short or to tight.Or do you know if you can change out the scabbard on them and use the J107m scabbard instead.
