**Disclaimer ** I have absolutely no ties with Knoxx except being a customer.
I bought a SpecOps stock from Knoxx after much investigation and put it on my Mossberg 500 12 Ga. slug gun.
Here are before and after pics: (Forgive the photography)

There are a few more pics at (and they may look better as well); http://www.picturetrail.com/gallery/...464&uid=680057
for those who are interested.
Installation: Backend - piece of cake if you h ave a socket set with extensions for it.
Forearm - Requires modification of the forearm for proper fit. It needs trimmed back for the forearm not to bind during shell ejection. Not a big deal but a kind of a pain. I used a dremel and it took about 1/2 hour. Make sure you have a forearm wrench for this one. This part was the worst part of the whole process. My opinion is that it shouldn't be necessary to modify the forearm but it was. You could go with the synthetic forearm from Mossberg but that's hard plastic and I wanted the softer grip forearm.
PowerPak - VERY tight tolerances but all and all not too bad
Ball end Wrench - recommended, but for the PowerPak more than anything
Hand All Grip - Place in boiling water for 5 minutes - no problem.
Overall installation: somewhat trying but nor really too bad. The forearm was the worst part and did take some patience.
Legality: It is legal to install on pumps. They don't have them for semi's because if put on a semi then it's classified as an assault weapon. <shrug> Don't ask me, I don't make the rules, I just follow 'em
I have a 2x7 Leupold scope on my setup that has about 4 1/2" of eye relief.
How it did:
They claim 90-95% reduction in felt recoil. I don't know if it was that much but it took the 12Ga shooting Federal slugs from a pretty good kick to about the equivalent of shooting 20Ga with birdshot. Virtually zero muzzle jump too. I shot 2 boxes in a short sleeve shirt and my shoulder didn't even register it. I did notice a slight irritation on my cheek. Not sure why but it's certainly not bad. The pistol grip (with the Hand All Grip) was very comfortable and the adjustable length stock made fitting to different shooters a 3 second task, literally.
The main section of the gun from the backend forward actually moves back about 1" before the two recoil reduction systems kick into play but 1" is about as far as it goes. Absolutely no way the scope would hit anyone, at least with the Leupold. I can't speak for others but from what I saw today anything with 3+ inches of eye relief, which is dang near everything, and there shouldn't be any problem.
I'd recommend it. It's not cheap but it does function as claimed. Only drawback is the cheek irritation and I think that's solvable if you're going to be shooting a lot. For hunting purposes, which is my main use, I'm not going to even worry about it.
They make it for:
Rem 870 12 ga
Rem 7600, 7615, 7400 20 ga (why you'd need it for
a 20 ga I can't figure out but maybe for a youth
just getting started? )
Moss 500, 590, 835, Maverick 88
Winchester: 1300-1200/FN Police series
They do make other stocks but the only one I investigated was the SpecOps.
