500® & 835® Stocks

Comparison of action slide lengths: top 7-5/8", bottom 6-1/2" Measure from top of threads to bottom of collar that holds the action bars. This measurement is critical to fit when ordering forearms or stock sets that include a forearm. For the most part, 20-year and older sporting shotguns and new tactical shotguns use the 7-5/8" slide. New sporting models have used the 6-1/2" slide for almost 20 years. There are exceptions, however. To be sure, measure! NOTE: Since 2006, most new 500®, 535® and 835® sporting shotguns with synthetic forearms may not use an action slide tube at all; rather, the pump handle will have two integral bars pinned into the handle itself. If you have one of these, you cannot use a forearm that was designed to go over an action slide tube without first buying the correct length tube and action slide tube nut. See photo below for comparison of forearm routing for more clarification – note that the top forearm below is routed for the shorter 6.5" slide and the bottom forearm is for the longer slide.
