I replaced the stock on a 870 with a knoxx recoil reducing stock when my son started shooting. The thing about the knoxx stock is you have to lean into or push back against the recoil for the spring to work. You can also adjust the lop..
I've been looking for one for my sister as she wants to shoot trap, turkey, and waterfowl. I've been looking hard at the Escourt youth model semis, good priced and seem alright. Charles Daly also makes one that the local 4H shooting club has. we're going to try that one out for her before we buy anything. This is a great thread, thanks for starting it.
I dont recommend a Charles daly for waterfowl. I bought one Wal-Mart had marked down to $125 because it set there so long. I had just turned 18. Great skeet shooting gun and lightweight. Winter and big loads are not suited well for it. It jammed often its first duck season and kicked like a mule. Ive heard others say the same. I did love it shooting skeet though, not bashing them.
