MK11 Mod 0 Project

Blackfoot 7 · May 18, 2020

I'm just a "fanboy military groupie gargling on the balls of Uncle Sam" sharing my latest project (because I like to share). It's a good minute to a minute and a half shooter and won't claim otherwise. Tried to get it as close to "correct" as possible, but of course had to compromise on one or two components in order to get it up and operational. Will be 100% when the can clears. Thank you for your time and consideration.

Excellent, thanks for posting up the photos and details.

That is a very nice collection!

Must say it is looking nice. It's been 8 years since my issued MK11 was replaced with another system. When did you submit the paperwork for the suppressor?

It's on order. Haven't even been sent the invoice yet.

So that’s where the lunchbox kit went

The Lunchbox lower isn't married to the MK11 upper. Just figured I put it to good use until the rest of the Lunchbox parts are released. Eventually I will be replacing it with another lower dedicated to this project.

Di you print the manual yourself?
Nice case!

I wouldn't mind that or "MK11 MOD 0" stamped on the lower receiver. The operators manual pictured is authentic. I do have a reprinted color copy as well.

you need this lower and a Douglas barrel spun by CLE.

I thought about having a barrel spun, but so far I'm happy with the Rainer Arms MK11 barrel performance. Squeezing sub-MOA with 175gr FGMM and it's barely broken in. Looking forward to trying some home brewed loads and M118LR.

Did you ever get that MK11 can in? I’m curious how the fit is with the Rainier barrel. I’ve got a build going myself and am considering this barrel.

Looks great, man. The Mod 0 is my favorite semi auto platform. For reference, the barrel is .725” at the muzzle on mine.

I did. No fitment issues. Goes right on. Haven't shot with it yet. Still waiting to clear NFA hurdles.

@Blackfoot 7

Any update on the can?

Still waiting on mine.

It's good to know though that the barrel is working out - my Mod 0 upper is an agency trade-in that, so it's not brand new.

Was trying to figure out where I could get a replacement barrel down the road someday if/when accuracy on the factory stock barrel starts to go.

No updates. My check was cashed on Sep 3 2020, so I'm thinking a few more months worse case. I don't remember if I did it through my trust or filed individually.

Yeah, my check was cashed on Oct 20 2020.

My last can was approved in 5 months and that was filed as an individual, so I'm hoping this will be around the same - hoping for sometime in the next few weeks.

Blackfoot 7 · Mar 11, 2021

Correction. My check was cashed Sep 1, but still...

According to the NFA Tracker the average Form 4 Trust approval is 197 days with an additional 20 days or so before the stamp is received. I'm currently at 192 days. Keeping my fingers crossed.

My MK11 can took 8 months flat. I’ve got another as well as an M110 headed to Form 4 first of the week

Reassuring news. Thanks.

Yeah I envy the folks with 5 month turnarounds. I’ve got 4 in jail all together and two just surpassed the 5 and 6 month mark. Looking at the NFA thread on here I’m seeing a lot of approvals from check cashed in September right now.

Yeah, it's funny - my Surefire 762-RC2 was approved in 5 months, and this was a Form 4 Individual.

I just assumed my Mk11 can would be around the same, but it sounds like I could be waiting longer.

261 days from check to stamp. 1 SEP 20 - 20 MAY 21. I got the call to pick up 4 JUN 21.

Glad to hear it!

Get some pics of that thing in here. Need to see it mounted to the rifle - in all its Mk11 glory.

Blackfoot 7 · Jun 7, 2021

I'll be sure to get some internet worthy shots posted up.

mallen45 · Jun 7, 2021

Working on a MK11 Mod 2 now as well. Both will be getting NF scopes in the near future.

In regards to the Rainier barrel, did you do the gas block yourself or have it done by someone? I am looking at going that route and wanted to know before I pulled the trigger on it? Have you found a load that it likes reloading yet, if so what are you shooting out of it? Thanks in advance.
