Never heard of them I prefer the knoxx stocks on a 870. Take that back thats the what sells on evel bay for 28 bucks facotry deal that you cant give away...just get a Knoxx.
I've done an older 1100 in black, and 870 in black and an 870 camo. The fit has always been good without any additional fitting. Price is reasonable. Other than that, not much more to say. Oh yes, one thing; the stocks are hollow and noisier when tapped on the side. This could spook some game when least expected. Tried to quiet one by inserting foam and surprised that it made no difference. ....
+1 to what Pahoo said.... the supercell recoil pad included with the stock is also great. I hunt with mine and havent had a problem spooking anything with the hollow stock
