Thread: Unique Arms X51

Hi, I am new to this forum as I am desperate to find parts for an old Unique Arms X51 22LR. I was gifted this firearm some years ago from an Estate, but unfortunately both the magazine and the rear sight has been lost. It is the earlier model firearm of which I believe it to be pre 1983 manufacture.... an from what i understand it will require the 10.4mm wide mag. I completely understand the rarity of these and I am hoping that someone maybe able to point me in the right direct to locate one. Either locally or internationally. I would appreciate any guidance
