StrangerDanger Posted June 25, 2009 Share Posted June 25, 2009 I was going to get a X400 for my XDm, but I'm a little over extended right now since I'm trying to get a LMT MRP piston upper for my AR15. My concern for the X400 would be the mode switch at the very bottom. My cell mate has one and we were looking at it's viability for a rifle/shotgun/subgun install. If you're looking at it for the lowest weight, that disappears as soon as you attach that XT07. Another issue with the X300/X400 series on a side mount is the battery compartment latch is exposed. One bump and it'll loose it's lunch. This photo shows you the slight parallax issues you'll have. Notice that the rail isn't aligned perfectly with the axis of the barrel. You're better off without the XT07. It was hard to push. The constant on button was nice though. Plus, the 7 inches is no where near enough in my opinion. Here is my Sidearmor with the Scout. I tried to fit my Surefire X300 on a LaRue mount, and the XT07. Think about where the mount is for the X300/X400 series. It then has the large tail piece that sticks out towards the back. Then, the stiff wire protrudes rearward also. I would guess this combo would extend the package about 3 inches further back. Now, you can get the XT07, and pull off their tape switch that has the picatinny rail mounted pad. Then, you have to buy a STxx switch like this: http://www.surefire.com/Plug-In-Tape-Switch-for-WeaponLight They have several different lengths to get the switch where you want it. The silver plug simply pulls out of the XT07 tail piece. Then you replace it with this one. If you mount the light on the left side (assuming you're right handed), you could easily run a short switch to the handguard. Attach the velcro to the handguard and the switch to a position you like. Personally, I like it under my support thumb. If you try to mount the light to the right side of the weapon, you'll run into wire routing ****. http://farm3.static.flickr.com/2446/3632303936_99696a5a56.jpg?v=0 Here you can see that if the light package extended further to the rear, it would begin to crowd my hands. http://farm4.static.flickr.com/3355/3632303902_2c8c92ca58.jpg?v=0 With the X400 being on the bottom of the light package (stupid) it will introduce approximately 2 inches of horizontal parallax. http://farm4.static.flickr.com/3303/3632303882_93963f82b0_o.jpg X400 - 450 XT07 - 165 ST Cable - 80 or Scout Light - 475 ST Cable possibly - 80 The package from LaRue has a 7" switch. (The price on the Scout light just went up in the past week about 50$.) http://stores.homestead.com/Laruetactical/Detail.bok?no=165 Also, I'm selling a 7" Surefire switch that I took off my Scout. It'll work on the XT07 tail piece if you want it. I never even used it. http://v4.beta.gunbroker.com/Auction/ViewItem.aspx?Item=132291912 If you want it, I'll sell it to you for 40 dollar shipped. Just throwing you some options. This has been my big project for the past month or so. Quote Link to comment Share on other sites More sharing options...
