I recently traded for a Knoxx Spec-Op II stock/forearm kit for one of my Mossberg 535's. I got the stock installed and went to put the forearm on, well the forearm would not go. The slide action rails on the 535 were different than the Knoxx forearm (slanted). I called Knoxx and explained I had traded for the kit and was wanting to order the right fitting forearm. The customer rep lady said "We'll take care of it" She said they would send me the right one for free even though I said I pay for it. I couldn't believe they would take care of me even though I had the stock/forearm second hand.
So hats off to BlackHawk/Knoxx Customer service!
