Mike,
I bought the 20ga/.22lr matched pair for my stepson a couple of years ago...I took the first shot with it right out of the box and even with a dove load in it, it kicked harder than my 12gauge with 3" BB.....The butt plate is exactly that...just a little plastic, curved plate screwed into the end of the stock...to be honest it kind of hurt like SOB....I bought a slip on recoil pad for it and my 11yr old is able to shoot at least 6 Rem. High Velocity slugs out of it at one sitting. He used it for deer hunting this year also, had a shot at a doe @ 10 yds but missed....He practiced shooting standing up, while hunting he was sitting and using a rest (my fault on the set-up)...the barrel only has the bead at the muzzle...I since taped a plastic, hollow cylinder (plastic spacer for a tv mount) to the rear of the barrel to help line up a little better...I shot it after that and it is dead on at 20yds now.
He will use it again for turkeys this spring.
