    930 SPX Tri-Rail from Aimpro
    I received the new rail for the 930 SPX from Mike Shain at Aimpro today. Here are some pics.

    The rail arrived in a sealed plastic sleeve, wrapped in shipping foam in a heavy cardboard box.

    The package includes the rail assembly and 12 soft rail ladder covers.

    That's an awful lot of rail! Especially with a little TLR-1 on there. Truthfully, at least for my purposes, I cannot fathom the need for that much rail on this gun. It already has a rail on top of the receiver to mount a red-dot if one wants to. All you need is a spot for a white light, and that should pretty much do the job. But, to each their own. Hope it works well for you.

    No problem.
    As far as the whole need thing goes, that's a slippery slope to go down. Sometimes it really doesn't matter what someone needs on their firearm. Some people buy their firearms and items to put on them because they simply want it. Not everything about or on a firearm has to be a need.
    Some people may need that much rail, or at least the ability to put stuff in a variety of locations. Some people may simply want it. If you think that's too much rail, you should look at the ETA Bulldozer rail. 6 linear feet of rail if it was all laid out end to end. Does anybody need that much rail? I doubt it. But there are people that want it and buy it.
    I don't know how many people I've had ask me when this railed forearm replacement or one like it was coming out. So while there may not be a lot of people that need it, there are at least quite a few that want it.
    All I have on there right now is the TLR; doesn't mean that that is all that is ever going to be on there. There is room for a breacher/lowoutput light on the other side, a VFG/AFG underneath, and a laser if one were desired. The rail gives the user options as far as what can be put on, and where it can be put.
    As far as what others need, I leave that to them to decide. Just because one individual has a certain set of needs does not mean that everyone else has those same needs.
    I have no doubt it will work out for me, it already is. I put this post here because there are people that want/need one, and this post will allow them to see it, and ask questions about it before buying one so they can make an informed decision without spending their money.

    How much does it weigh? or differential to the stock forearm?

    I won't be able to weigh it until I can get to the dope scales at work tomorrow or Tuesday. However, Mike said that the rail runs about 14.5 ounces, for a net gain of 9-10 ounces more than the factory plastic forearm. It is obviously slightly heavier, but with the location it is not very noticeable.

    Here's some pics of the rail/reciver interface at the bottom:

    There's a technical "feature" that I was wondering about that Mike gave me a little info on that I'll be posting about once I get a chance to check it. If you notice in the interior pic there are some cuts at the front in the collar or plug. Those are gas bleed off chambers. Mike advised that they've actually seen some improvement in shotguns that don't cycle low power loads with the rail installed. If it works as I've been informed, there will be a lot of people that could take advantage of not just having a railed forearm but also a more reliable shotgun.
    As for the utility of that much rail, here's another use that someone mentioned to me. At a 3 gun match there was a shooter using an offset side-mounted RDS for slug use at long range. The exact same concept as used on carbines and rifles, and she was making hits at 120 yards. The guy asked about mounting an RDS to the Tri-Rail, so I slapped one on there. So another use for the rails.

    Where do you get a sling attachment like what is on the buttstock there?

    That does look cool. For those that may complain that its too much rail... its really no different than a quad rail on an M4. Using every square inch of rail is not the point. Options to locate stuff is the point so if you only have a light and a bunch of rail covers...I am all for it.

    It also gives you some easier options on sling mounts and the like, not a bad setup at all really. I am looking for ideas on my 930 HD, I need an extension, and I might just need that forend as well.

    You're exactly right. I don't have a pic of it, but I've got a sling point on the left side of the rail.
    The Tri-Rail offers options. It may be a case of wanting more locations to put one or a few items, as opposed to loading up the rails with every conceiveable item.
    Depending on the sling used, the rail offers the user the entire length of the rail to mount the forward sling point. A three point user may want the sling all the way forward, while an adjustable two point user may want it in closer to the reciever.
    Mix:
    The rail is about 11" long, which is just under the length of a standard rifle rail handguard, and it is only three rails as opposed to the 4 usually found on AR type rail systems.

    There have been a few outfits working on this. AFAIK, Aimpro is the first to actually put one in production. The ETA Bulldozer has been out for a while, but is a different rail with a different intent and focus. I've also been surprised that it has taken this long for one to come out. That said, I think the Aimpro model has been worth the wait.

    that was a long time ago, I just put up a new video from my sordid law enforcement past http://www.youtube.com/watch?v=oJYsX1YGiGA

    I kinda wonder if there is enough weight forward if you had a single point hooked up right at the closest point to the receiver if it would hang right. I guess what a fella should do is just get the stock adapter and go with a quick adjust two point or three point.

    I will check that out tomorrow since I will probably home with a sick kid again. I don't think there will be enough weight forward. The receiver plate would be the best way to set that up.

    I have tried the receiver end plate deal and don't really care for it in a Mossberg application. I can be just about as happy with a 2 point as anything anyway, and this looks like a great way to do that.
