ON the down side, it doesn't matter what sight is fitted or the size of the hole, the position of the moon or the breakfast menu that day. The rifle isn't a target rifle and never will be. And while the rear sight base is articulated against the foresight and the barrel, this or any sight mounted to the TMH will not make a jot of difference. Just my opinion based on nothing more than a goodly dollop of experience, a modicum of common sense and what my mum used to call the bleedin' obvious. Just my view of course.
