If you're looking for a Canuck pump action replacement stock, the Canuck branded Tactical stock is surprisingly very good! I just received mine in the mail from Bullseye London. It has an adjustable cheek riser with nice controls, two shell holders (nice and snug, but will test with 00 magnum buck later to see if they hold well) and a spacer to extend LOP. Overall, it has transformed my pretty unmanageable birdshead grip set-up (good for my rucksack) to a very pointable, comfortable and practical gun. Only $35, made in Turkey, not China. I also purchased an RX Arms sling plate and handstop (a must for short barrels), which fits perfectly and is nicely finished! It also makes for a handy gun stand! I will post pics of the transformation later. I am just waiting on my 11mm dovetail to Picatinny/ Weaver adaptor which I picked-up from a non-site sponsor for cheap.
One last thing, I was cleaning both my Canuck and Mossberg 500 ATI Tactical (best shotty I have ever owned, and I have owned MANY), and aside from the Canuck being just as well built, it is by far and away MUCH easier to strip and clean. It's like the AK47 of the shotgun world. Just unscrew the mag cap, barrel and pump assembly falls out. The pump assembly amounts to three (3) parts: the bolt carrier/rails (milled!), bolt assembly and forend grip. I bet I can disassemble and reassemble in 10 seconds. Loving this gun more and more every day.
