Marui M4 RIS Question
 

http://www.uncompany.com/pageproduct...sp?prodid=6150

I'm looking at buying a used one minus the (outter barrel) mounting brackets. So my question is:

Does the RIS attach to the receiver AND the outter barrel?

If so, is there much play/wobble when the mounting brackets are not attached?

I think I may have some mounting brackets made or jimmy rig something up myself if they aren't the main things supporting the RIS.

Also, is there room to fit an 8.4v mini in there?

Thanks,

Mark

Edit: Just noticed this is probably is in the wrong section! Move if needed, thanks.

Yes, the supports are needed unless you have a one-piece outer barrel, otherwise you really need those supports as the barrel wobble is obvious at first and will only get worse. A one-piece outer barrel is the quick and easy solution. However, depending on the outer barrel, you may lose the ability to fit a small battery in the RIS, and may have to go with a Crane stock, AN-PEQ, or RediMag to house the battery.

I have a TM M4A1 new type w/ the one piece outter that's supposed to prevent barrel wobble. Discovered barrel wobble after my first game so I did a shim type mod and now it's pretty solid. So without the brackets it should be fairly solid by itself?

When you say barrel wobble, do you mean just the outter barrel wobbles OR the foregrip/RIS will wobble with it?

Just the barrel (on the old-type M4's) would wobble, but because the rail is held in place by the rear d-ring and the front retaining ring by the front sight (which is attached to the barrel) you may have some movement of the RIS unit, too. You *shouldn't* have a battery-storage issue with the "new-type" barrel as it is bevelled and stepped to accept a battery to begin with.

The ultimate cure (and will make your RIS solid as a rock, BTW) is to add a Laylax Nitro Rail, which attaches to the top of the RIS and goes straight back and bridges to the flat-top of your receiver. It make the whole thing "knock-down-trees" solid.

You can see a pic of the Nitro Rail/RIS combo here: http://img.photobucket.com/albums/v5...ors/ecco16.jpg

I bought the actual rail and RIS from the guy in this picture, BTW.

This is what I'm looking for?

Any cheaper?

Also, I've been told by one source that I can't fit a battery in the RIS. Is this true? And if so, would a bit of dremeling fix the problem without compromising the RIS too much?

Yes, that's the right part. I couldn't fit a battery in mine, but I figured that was because of the outer barrel. I don't think there's much inside the RIS to dremel out, anyways.

No, you can't fit a battery in a RIS. It's just not possible, due to the profile of the RIS.

You'll either need to go with an AN/PEQ2a LAM type solution or a rear stock solution (full stock, G&P crane, etc)
