I just picked up a colt 6920 with the Magpul furtiture on it.  I'm wanting to mount a Grip Pod GPS-02 on it, so I am going to need to mount a picatinny rail on the underside.

I have seen that Magpul offers some polymer bolt on rails, but I not to thrilled with the sound of plastic bolt on rails.

So does anyone know if anyone makes aluminum picatinny rails that are a direct bolt on and what length I need to get for the setup I plan on running?

And finally, will this be a solid set up with the MOE handguard and vertical grip/bipod, or am I wasting my time?

Thanks

The magpul polymers rails are good to go. They are very stout and will not break if thats what your asking. I have some on one of my AR's and I have never experienced a problem with them. If you are so worried about it, Why don't you just get a Daniel Defense drop in rail and call it a day?

Get the Magpul rails, they are gtg.  I use a pair on my A2 build, and can testify it's rock solid.

I have the Magpul MOE grips and you should feel more than confident using the plastic rails.  I have a VFG and light attached to mine.

I ran a MOE vertical grip on mine for awhile and it was very solid. I have almost bought nice railed hand guards on more than one occasion, but the value the MOE offers stops me every time.

i dont have the tools nor know how to install the DD rail...plus all my other ar's have rails and i wanted something a lil different.

The magpul rail sections are fine. I've mounted a grip pod to my AR using them before. I've also put some weight behind it with the bipod deployed. It will be ok.

You could search and probably find a rail system that WILL mount to the MOE hand guards, but the polymer Magpul rail sections were made for it, and several people here (myself included) have used them with no problems, durability related or otherwise.

On another note, if you're just looking to mount a vertical grip, the Magpul MOE vertical foregrip mounts directly to the MOE hand guards, no rail needed.

im trying to build something real lightweight, so thats why its appealing to me.

i think the MOE vert grip attaches a lil differently.  If you go with  Grip Pod or other aftermarket grip, you will need a rail.

another thing i didnt think abotu is that i have a larue FUG and i dont know if it would eat up the plastic rail?

yup..i believe the gun ever comes with the MOE vert grip...but i want a bipod and i think the grip pod would give me the lightest combo.

The FUG should not eat up the MOE rail sections if it is mounted properly. If it is installed loose, most likely.

Magpul polymer sections are definitely GTG. had them on my first build with no issues. The actual mounting hardware for them is metal, if you're worried about 'melting'.

i assume that is the carbine length guard...what is the length of that rail section?  they come in different lengths and that looks about the length of rail i want.

thanks

rjpar,IM me I have a like new 5 inch magpul rail section for you for FREE if you want it. Looking for the mounting screws and nuts right now but I am sure I have em somewhere..They need to put a Pay it Forward section here for stuff like this. The plastic rails are really solid in my opinion. Have used em with a Bipod before with no problems...Thanks

The handguard is plastic, the grip pod is plastic, so a plastic rail section is not going to be any kind of weak point. Odds are, the handguard will break before the rail section anyways.

[edit] Oh man, I didn't even read your FIRST line carefully. Reading other posts I thought you were talking about the MOE grip. I'll leave this for some noob  to read. For what it is worth I find the MOE grip very comfortable for some reason. I mean it doesn't have any finger grips or nothing but it just "fits" great. I also have all separate bipods as the combo products always looked like they would be weak. I'm not saying they are and would be interested in trying on someday.

There are two different VFG for the MOE furniture. First is the MOE MVG.

It attaches directly to your handguard with supplied screw and "nut".

Second is the MOE RVG (railed vert. grip)

It comes with a very short rail (only the width of the grip) that attaches to the handguards then the grip attaches to that.

FYI, all my components on my AR's with handguards (not FF rails) are attached on polymer rails, including all bi-pods.
