View Full Version : DD MK18 RIS II upper build
I plan on building a DD MK18 RIS II rail and a 10.3 or 10.5 barrel and a BCM FA BCG. I can't find the photos of the DDMK18 in the past of a clone build using a Colt upper Rec and a Colt 10.3 barrel or a Noveske 10.3 or 10.5 Barrel. Please someone please post photos on here of all the MK18 DD RIS Uppers?

Stick you have enough room to hang a can off the end of that?

Not Stick, but it really depends on the can. I use an AAC M4-2000 Mod 07 with a 10 7/16" barrel and a Mk18 rail. I'm using the Blackout mount and I have about 1/16" room between the can and the rail.

I have a 10.5" Denny's Guns barrel. and bought the DD MK18 rail and wanted to make sure there was enough room to hang a can off it. Now if only my favorite gun store would go Class III/SOT. (Hint, Hint)

Got the SOT last week should have some stock in a few months.
Awesome news, Robb! Love when a plan comes together...

Well now I guess I know where to spend more money.

Yes, there is room for a can - the system was designed that way. It's damn near flush when mounted.
This one has a 10.5 in barrel and the Knight's Armament flash hider. Lower is the usual M16A1, with SOPMOD stock, H3 buffer and CS buffer spring.
I don't know the exact ROF, but it was noticeably faster than the Minimi we had running in the adjacent lane. It handles like a dream.
Anything else?
Gotm4, where did you get your "Ticket to Allah" Dust cover? I like and want one like it?

Here's a MK18 build I did last year with a Noveske 10.5" barrel:

Stick is my photog hero, I just have to steal his camera away;)
The MK18 thread shoulder is coincident with the end of the rail system. That makes it compatible with very few silencers as a lot of them extend back slightly behind the thread shoulder.
Here you go...

LOL, "that" camera cost me more than I care to remember, but I would rather lose it than the glass.

I've been trying to figure it out based on pics and info on Daniel Defense's site but they don't have too much detailed info or pics on it. I know the OAL of the rail is 9.5" according to their site. I'm hoping to build my mid-length upper with a vltor mur and a 16" noveske barrel w/ pinned switchblock. Any ideas if the switchblock will clear the rail? I want just enough clearance to be able to change the setting but not far enough to expose the gas tube. I think I read on another thread that the mk18 rail clears the switchblock just about the same as the noveske marked SWS rail. Any ideas?
What is the length of this rail? It looks over 9" I assume.

9.5" I believe
Can anyone tell me if the Noveske 10.5" CQB Barrel w/ switchblock fit will under the DD MK18 RIS II ?

I have that exact setup, and had to cut a hole in the rail to adjust the Switchblock.

If I was to mount one of these on a mid length upper with a low profile gas block, would it cover the gas block completely or would it be partially exposed?
Nick B, can you post a couple photos of the your whole MK18 RIS II clone? I would like to see a closeup photo of the cutout area?
That's what I'm talking about!
Got the SOT last week should have some stock in a few months.

anybody run one with an 11.5?
I have had a MK18 RIS kicking around for a long time and am getting close to building it up.
Not Stick, but it really depends on the can. I use an AAC M4-2000 Mod 07 with a 10 7/16" barrel and a Mk18 rail. I'm using the Blackout mount and I have about 1/16" room between the can and the rail.

That is an awesome looking rifle. No cans here in VT it is a fish and game violation with a $15 or $25 fine. Is that FDE furniture? Mine looks alot lighter that yours. Could just be the lighting. Thanks for sharing.

wouldn't there still be federal penalties? I feel like I would have gotten a can by now if it was only $25 fine. Shit, Im illegally parked right now.

I used on with an 11.5 and G5. Worked well.
I sold it and am now waiting 3-4 weeks for DD to make more :-(
Will AAC M4-2000 clear when on a 10.3" barrel? Looks close with 10.5" so that .2 may make a difference.

I just checked with my M4-2000 and 10.5'' LWRCi upper that I bought to help but together a Mk.18 Mod. 1 clone, it does clear. It's RIGHT up against the rail though. It touches the rail.
I wouldn't do it actually.
I'm bumping this one because I'm having a problem with a DD 10.3 and the RIS II rail. M4-2000 won't mount without hitting the rail. WTF?
It'd need a full 1/4" shim or more to work. Any ideas? (barrel length checks out at just under 10.5")

Yet another Daniel Defense quality control issue?

What mount are you using? I have the M42000 on a DD Mk18 upper but it only works if you use a muzzle device with the wrench flats behind the teeth. The 2 baffle Brake does not work. Only the Brakeout (Single baffle with 3 prongs), or the Blackout.
That was it, Jackson! We figgered it out yesterday when I spun on an extra 18T mount I had handy.
NOT a DD problem. AAC's nonsense this time.
Glad you got it resolved, I have a 51T Blackout on mine and using the Mini 4 I have "just enough" clearance.
