If you're interested, ERGO makes a very nice rail shotty fore end for a fraction of the price www . ergogrips . net They will ship to Canada and offer a 10% discount to military and LE members. The lady on the phone is top notch, truly a pleasure to deal with. I think I paid ~$80 for mine with rail covers and I had it in a week. It's all one-piece machined and fits my 500 like a glove. I owned a surefire picatinny front on an other shotty, and I do not see a quality difference between the two, in fact the ERGO fit very tight onto the action tube, while my surefire needed the tube nut to be tightened right up for a secure fit. This could be a small size difference between the mossberg 500 and remmy 870 action tubes though, I've heard of a couple 870 owners having to loctite or put a small piece of scope tape in the tube for a tight fit. The price and availability make it an easy decision if I ever need to outfit another gun. I'd highly recommend them.
