Only tried once so far - worked as advertised/reviewed - BlackHawk Knoxx Comp Stock Shotgun Stocks

I've only used this stock once so far, and it worked well in reducing recoil. It also looks nicer than the original stock with its Hogue grip.

I have a SureFire foreend so that I didn't put on the included fore-end, but it also looks like it would work well, though I also read it's a little shorter than the stock one. I would research whether it is though, and I also remember reviewers still liked it, and I can't argue because it's also Hogue.
Pros: Regular-Style Stock, Heard Good for Pump (Rem 870), Easy to Install, Nicer Than Original Stock
Cons: Reportedly Less Recoil Reducation, But It's Likely More Natural, e.g. Doesn't Swing Side to Side
