M42000 for DD MK18 Factory SBR (10.3)

[Bullseye_Josh]

I'm scheming my way into one of these rifles. I don't currently have a 556 silencer, but plan to get one. Does AAC have any plans to make a blackout/brakeout mount with enough meat on the backside as to push it forward far enough to clear the rail the way Surefire has done with their FH556-212A mount?

Anyone have a custom one made? Maybe with a Battlecomp as the brake part?

Thanks!

Know 3 guys with the same rifle and Model 07 & 08 M4-2000's using blackout and breakout mounts. No issue. It is close, but it clears the rail.

You sure they do not have the Noveske 10.5 mk 18 ? Are they running a shim to space it out ? Strange never seen a 10.3 with a DD MK18 rail work.

Nope they are DD's. The factory is here in Georgia and we as LE here do a lot of business with them. Our agency just bought right at 50 Mk18's and several guys had already bought their own Mk18's from DD. I have personally shot my boss' which had a breakout and a 07 M42000.

Don't buy based on me though, call AAC and they can confirm.

I was told by aac and DD and tried myself and they bottomed out. Wonder If they shimmed them out or threw 10.5 inch barrels in there.

I will ask to make sure on the barrel lengths and if shims were used. My supervisor is out of the loop today, but I will inquire early next week.

Just tried it again no go.

I talked to someone a while back and seems like they told me they used shims on their setup.

how much space do you need?

Are you using shims behind the brakeout?

[66427vette]

No shims are being used it timed perfect with out needs about another .1 . I have a the Noveske Mk 18 version with 10 .5 inch barrel fits perfect.

I was just thinking shims would be a cheap option . . . .100" isn't much

[66427vette]

I just threw it on the Noveske .

I will post pics later.
The new blackout fh that has a little extra meat in the back will clear just fine. The brake or the older blackout fh will not. I used a spacer only to time it correctly.

Shitty phone pics but you get the idea. Last pic shows the different mounts.
