I'll answer some of them ??? fer him....He's got an 870 but was wanting a camo stock, but then I found Boyds custom stocks and they are AWESOME stocks...He liked the tactical stocks that can be adjusted but fer the comfort and shock absorbing would probably go to the thumbhole stock. He will be using it to hunt birds/deer, and shoot skeet so there will be a variety of ways he'll be using it.
Thanks fer all the responses fer Logan.....:letsdrink
For skeet the thumbhole or ak style is not practical. You need more of a traditional type stock some people do modify traditional stock with adjustable combs and recoil reducers.Like this mine has an adjustable comb to raise and lower point of impact.
You'll shoot your eye out........Just kidding. Nice gun. The 870 was my second shotgun that i recieved when i was about your age. Killed alot of deer and turkey with that gun. You'll be very happy with it. Just take good care of it and it will last you a lifetime.
