Jason,
The M4A1 FSP is in stock and will be added to the website soon. In the meantime, one may order over the phone. The price is the same as the M4A1.

Very nicely laid out carbine.
Mr. Rice
I don’t see the GL/SSC on your website. Also, is the 9.0 Omega going to be available in FDE? Thanks.
Jim
The RIS II GL/SSC is currently not available.
We now have the RIS II M4A1 FSP available in both black and SOCOM approved Flat Dark Earth. (Pics to follow)
The Omega Rail 9.0s are also available in FDE.
That sounds great. Will the RIS II M4A1 FSP be a regularly stocked/manufactured item?
Absolutely.
Just ordered a M4A1 RIS II FSP in FDE. The .mil discount is very nice.
Thanks DD!
I am really starting to think about one of these for my LMT. It may be worth the hassle of removing the Perm FH and selling the LT 7" to get one of these.
Stick, do you have any intentions of mounting one of these on a weapon any time soon? I would like to see that…
Here’s mine, installed by the great folks at DD!

is the .750" gas block the one meant for underneath the Mk18 rail?
What length barrel is that? 14.5"?
Yes, it is a 14.5.
I’ve got a 10.5 inch as well, with the MK18 rail that they installed for me. I think I’m going to run that this tour in the desert as well.
I’d take both, but I’m afraid I won’t be able to get more than one back when I return.
more pics can be found here
Sadly, I’ve got a shortage of barrels, so its going to be a little while until I can build this one up.
If you check out the link over on WEVO, you can see my old RIS II prototype setup, as well as an unofficial history of the DD RIS II rails.

Haven’t we all. That stinks, but I guess it’s just how thing are right now.
Yeah I have checked out the “evolution” of the RIS II rail a bunch of times on WEVO and it never gets old.
Thanks, thats a heck of a compliment.
From the looks of it the RIS II FSP would require the removal of the FSB to install; is that correct?
Thanks,
Bill
Okay, serious question here:
What is the real difference between the Lite Rail 12.0 FSP and the RIS II? I get that the RIS II is a two-piece and allows free-floating an M203.
RISII is 9.5" long, just a tad longer than a 9.0 (obviously).
