So my buddy was over last night till 2am installing the Hogue stock set on his Maverick 88.  It fits like a glove, with the right parts.  We ended up getting the Mossberg 6 3/4 action tube assembly and the Hogue forend adapter nut (which is longer than the Mossberg nut) and it was matched perfectly.  He then threw on the 12in LOP stock on to the 88.  The washer that came on the 88 wasn't quite wide enough to let the bolt seat evenly in the Hogue unit so we dug around and found a slightly larger washer and it worked better.  Everything seems to work so we'll take it to the range this Friday to test her out. 

So my buddy Justin is trying to install the Hogue Stock kit with the foreend, 12in LOP onto his Maverick 88.  Up until now, we've been hearing that the Mav 88 is almost a virtual clone to the Mossberg 500 and most parts are interchangeable. 

Well, we got he stock kit and started with the forend and immediately ran into our first roadblock.  Looks like the forgrip on the Maverick 88 is a bit different than the Mossberg 500.  On the Mosserg 500, the forend is actually two seperate peices.  The grip itself slides overtop of what is called an actional slide tube assembly.  Apparently, some of the newer Mossberg 500s come with this solid plastic forend with the pinned-on action bars which many people get rid of all together because they allow no options for aftermarket forends. 

Most posts we've read all recommend replacing the Maverick 88 unit with the 7 5/8 in action slide tube assembly (retails for $54.99 from Midway USA) but we've also seen the 6 3/4 in action slide tube (retails for $25.99 from Midway USA) so we'll have to do a bit more research.  We've also read that some action slide tube assemblies don't come with the Mossberg action tube nut (retails for $9.99 on Midway USA) for 7 3/4in action tubes (retails for , and other posts say we need to get Hogue forend adapter nut (retails for $12.99 on Midway USA) that's required for the 6 3/4 in.  Looks to me like you will only need the Hogue adapter nut (which looks longer than the Mossberg nut ) if you have the shorter 6 3/4 in unit, but looking at some prices, it might be cheaper than buying the longer 7 5/8 unit plus the tube nut from Mossberg.

I'll post some pictures of our mess as soon as I get a chance.
