DD RIS III

[drtywk]

I'm thinking this might be an alternative to the MK16 rail for Mk18s. It would be much easier for a unit armorer to just swap these out using the old barrel nuts already on the guns rather than having to disassemble everything for the G rail.

Did anyone actually read the post or comments on SSD regarding this rail? It was developed at the request of a Marine Corps unit, but was not selected. It is being evaluated for other programs and it looks like DD may also launch them commercially.

I personally prefer the Hodge Wedgelock and the new Geissele systems over the DD system. I am also really looking forward to the new Pinchlock rails from
Hodge.

I think part of the issue is there are other systems which install quicker and with fewer parts. While the RIS II is a solid system, if you look at the Geissele / Centurion Arms / and others, the use of a non-timed barrel nut along with only two or three screws from the side make for a rapid installation. This means nothing to the average person, but combine the fewer parts to maintain (or lose) along with the time involved in rebuilding hundreds of weapons, and it starts to become important.

The attachment system of the RIS rails requires that the rail itself be pretty wide and by default, heavy. Can't they do something a little more streamlined?

They absolutely can, it is more a question of if they see a benefit in doing so. In the pictures shown, they are using (or what appears to be) a standard RIS II which had the sides milled and MLOK style slots put in. Same extrusion and existing hardware keeps costs down. If they were asked for this, they did what was requested.

With Geissele making headway into the military rail game, DD may have an agreement in place with them, or may already have other samples made which feature simplistic installation. None of us know at this point outside of DD and G, but I wouldn't be stunned if both ideas were in place.

Think of it this way. If SOCOM or the Army wants an complete upper receiver group, and Geissele makes the rail with DD making the barrels, they both win.

And anyone who has installed a 6 bolt RIS rail knows they are a pain in the ass by comparison.

The only way to do them in volume is to have a long flex drill piece and use the right bit. That way you bypass the cursing and quarter turns with the allen wrench.

I’ve always used ratchets with extensions to reach the head. Normally works pretty quick, but I’m only working on one, I can’t think of how it must be to work on them in mass.

Striking resemblance to the new Hodge rail:

Mr. Hodge mentioned on another forum that this rail was developed to spec for a government request, I wonder if DD was competing for the same contract.

That painful install is Juice worth the proverbial squeeze.

I'm liking the looks of that. Hopefully they will be able to found, unlike the Wedge Locks which are usually out of stock everywhere.

Don't tell me that you have not only embraced the idea of rails, but that you prefer the pimptastic ones!?!?! Hard to get more combat pimp than the RIS II series....
