View Full Version : Building a Mk18. Opinons on rail.

27 March 2015, 14:53
First post here.

Been looking at some of the builds here and wanted to try the sbr route. I'm planning on a Mk18 barrel 10.3" DD and have looked at 9.5" rails. There aren't a lot out there, but wanted some opinions on these or other options. I do not want a RIS II or any quad pic rail.

I want to cover the barrel as much as possible but still be able to mount a suppressor with QD methods. 9" rail is of course an option, but I really like the barrel covered.

Here's what I have so far.

Geissele (hard to find)

Centurion CMR

Hopefully these pictures post.

Any input is appreciated.

Here you go, 10.3 Rainier Barrel on a 9.5 Geissele MK2, and a DD 10.3 Barrel on a CMR 9.5

Non-DD handguard = not a MK18

However, I'm buying a 10.3" DD barrel myself, and planning on buying a BCM KMR 9.0 for it.

Next you'll tell us it can't be an m110 if it ain't kac...

What's horrible is the call of duty crowd that can't just use normal terms and has to dredge up acronyms that don't mean anything outside the mp name.

"Mk18” is the "lol wut" in this conversation.

MK18 MK19 wutever it takes....

I agree, it's not a mk18 or CQBR, just a DD 10.3" barrel. Noveske chainsaw receiver set arrived and Form 1 filed yesterday (my first NFA paperwork, eform through a trust).

Kind of leaning towards the CMR. Thanks for the pictures UW.

BCM isn't a bad option. NSR is another for the 9" varients.

Mega will have a 9" soon also.
