Just thought I’d do a write up on my MK18 builds.
I never thought of myself as a cloner, but I’m friends with a lot of them, so here my two, not so clone correct attempts.
The first rifle the Mod 0 started life as Colt 6920HBPW
So a heavy barrel, 14.5 with and extended A2 pinned and welded.
I purchased this rifle with the intention of making a Mod 0 MK18, I opted for this over the traditional 6920 because I wanted the heavy barrel. I had spoken to the gentleman who is going to do the work and cutting down the barrel, I told him the flash hider was pinned and welded, he told me it would be an extra hundred dollars for him to do disassembly on the barrel since it was pinned and welded I couldn’t remove the barrel nut assembly or FSP. I said no problem I got this.
I used the dremel and took the pin off and removed everything and saved myself $100. Obviously since I was getting the barrel chopped down to 10.3 the existing threads didn’t matter. So I was rough with the dremel.
Once the barrel was chopped, I reassembled every, and already having the accessories on hand I was able to put it together, I prefer Free Float rails. And since I was already going off playbook with the heavy barrel, I choose the Free Float RAS from Knights over the drop it. Other than that, the build is Kosher Clone correct. Complete colt parts.
As for the Second MK18 or the Block II.
It started life as a 2013 Colt Socom. M4A1 without the property mark.
I then took MANY liberties, well cause frankly, I don’t like the Block II CQBRs.
First thing I wanted was a FSP. So I removed the barrel from the Colt M4A1, sold it and replaced with a factory colt 10.3.
Then I was able to get a chopped M4A1 RIS II rail from ChopBoss, chopped to imitate the MK18 RIS II FSP, since they are no longer produced.
Second I HATE EOTECH optics. But wanting to keep the Block II vibes I choose to build using a tan ADM mount, and a T2 with a FDE Tango down cover to at least give the color the right vibes. I then placed behind it the Eotech G33 as I do love those magnifiers.
I do love the right side light on the mod 0 so I want to emulate that as close as possible, I choose the surefire M300 mini scout, in an ADM FDE QD mount.
The Block two has the Tango Down VFG, but I find it’s too large for my hand to shoot comfortably, so I chose to retain the KAC grip from the Mod 0 but grab the taupe to match the ready of the build.
The Bolt carrier is a LMT enhanced carrier with the Colt internals.
SSA-E trigger
Both SBRs have Geissele Super 42 buffer systems in H3 configurations and run immaculately well.
Currently the “Block II” has a RC2 pending in jail.
I hope you like my custom take, with artistic liberties of the MK18 builds. Neither of them are clone correct, But they were never meant to be.
My Block two isn’t done, but it is nearing completion.
