My uncle had an old Mossberg 342 and maybe one of his boys has it now. The tip of the forearm (about 8" or so) was on a hinge and would fold down to act as a vertical handle. It was ugly and looked like a club. It was topped with an old 22 scope - one of those old skinny jobs. But boy could that rifle shoot. I remember taking it out with my two cousins and we were all saying - NO WAY. That rifle would make any target 22 sweat. At 25 yards it was shooting such tight groups it was insane.

been doing it for years! great fun
