What I did was cut a bunch of vinyl stencils in flecktarn patterns and stick them to the gun (after lightly sanding and cleaning with mineral spirits). I painted black first, added some stencils, then brown, added more stencils, red - added more, green, and so forth until the last coat was dry. Then I removed every stencil, which took a while. I'm very happy with the results, but not sure if I'd go through the process again unless I had a lot of free time to do it. Since the dark OD was my last coat, that color is the most prominent, with black being the least since it was first.







ETA: This was the basement in my previous home: before anyone calls out the janky outlets mounted to boards - I eventually fixed those with proper conduit and drop down boxes. I discovered that fun feature when I "unfinished" the basement from the previous owner

I have a couple of Mk12 Mod1 FDNY clone questions.

Are the rings pictured in the classic FDNY photo A.R.M.S. #22 High rings? I know they are #22, I am just checking the height.
Are the there more photos of the FDNY rifle, I am aware of the photos of the rifle in pieces and put back together at Knights Armament Company.



I took the Armalite AR receiver off my Mod 0 and installed it back on the KAC FF PN 21318 RAS.

I am still on the hunt for a 5.56 #36 S-EX Swan Sleeve. For time being I am using a machined A.R.M.S. #36 EX AR10 OSR to work as a stand in until I am successful in locating a 5.56 #36 S-EX.

I do have a correct surplus tear drop FA coming.

I likely won't ever have deep enough pockets for the correct period Ergo G rear grip.




I'll close by saying after shooting it today I am not the biggest fan of the A.R.M.S. #22H rings on the #36 Swan Sleeve when compared to a Mod 1 #22H on a receiver or a Mod 0 on a #38 rail with #22M rings.  I have a set of #22 Medium  NLS rings but they would not be able to clear the KAC large knob 200-600 sight.  The #22M rings also would not be clone correct if I am correct that #22 High rings were used on the original rifle.

Any comments or referrals on locating a #36 S-EX swan sleeve are greatly appreciated.

They are the High rings. They're not good on a Swan Sleeve yeah, you want the scope to sit low on the rifle. SSgt Miller just took the issued scope and rings and threw it on the sleeve, he wanted the better eye relief the #36S-EX gives you and because he had to keep the iron sights on the gun he had to keep the tall rings on the scope for the eyepiece to clear it as you mentioned. I've also seen claims that his rifle had the Armalite handguard, they made uppers for the Mk 12 program and got a license from KAC to produce a copy of the FF RAS to help fill demand. It would make sense given the Armalite receiver but since they're identical there's no good way to tell which rail he had

As mentioned they're the #22 H.  There was a member here that had one of the Armalite marked rails.  I haven't seen him on the forums for a long time though.  I don't know of any other photos that have been shared.  Here's an older pic of mine with issued scope and barrel.

Sold my not correct but pretty close 3x9 as I unfortunately needed to free up a few dollars. So I guess I'll take this opportunity to make this more better as cash becomes available....and elusive parts.

Currently:

CLE barrel
Full address FSP
Winged #38
NLS #22
NLS #32
Non winged #40
Non winged TRS/TRR whatever that top rail is forgot.
Key hole upper, have a like new AF upper I'm thinking of swapping.
Non marked PRI side rails, and three dot bolts
Original welded latch PRI charging handle




Lower, could use some improvement across the board and might got to an A2, might go a Intlmilco at some point

Optic, we'll see.

This may be a dumb question, is that SSGT Miller in the bottom photo with the ball cap and Mk12 from the left side? Do we know if the FDNY rifle was used by SSGT Miller since no one is identifiable in the photo with the FDNY stock stencil.

Looks like I don’t have pic of my Mk12 clone on this device.

PRI 18” Mk12 Mod0 upper on an H&R blem lower with an Ergo grip, A1 stock and a generous amount of Rustoleum. Correct ARMS no nub rings. No ambi safety, no teardrop FA, does have Geissele SSA-EX - the earlier gov’t version with standard trigger profile, not lightning bow. Looks and feels good to me and I’ll post pic later.

Planning on an OCM6 when available.

Haven’t decided on optic; a correct scope may be more than I want to spend. I have a late 1990s vintage SWFA Tasco SS 10x mildot that would work and has matching paint. The Bushnell LRTS 3-12x44 has the G3 reticle which I like and have on other optics. The ideal for me, I think, would be the Leupold TS30-A2 Mark 4 2.5-8x36mm TMR - 8x seems about right to me for 77gr pills. I live in the Southwest and have ready access to places to shoot where I can enjoy full advantage of the rifle’s capabilities.

I did write Leupold asking for a special retro run, noting consumer interest,  and got back:

“I have passed this suggestion along. As a Mk12 enthusiast myself. I would enjoy this too!”

Welcome thoughts on optics.

CPW, who are enforcing it, clearly stated it applies to any firearm which meets specific criteria at point of sale.

A stripped lower does not have any of the features listed that require the 'additional training'.

I mean it'll all be tossed in a couple years anyway after the lawsuit is filed so compliance is optional lol

7/23/2026 2:19:15 AM EDT
[#39]
Looking for some help on lower selection for a MK12 mod 1; IMC has a few different options for year/serial range.  On their non hydramatic lowers, is there any particular lower style that would be more correct out of: 1969 1.6 million seri., 1971 4 million seri. , or 1975 5.1 million?

I'd like to go with the hydramatic lower as there are plenty of reference photos, but IMC production can have pretty long lead times between batches, so I may have to spring for whatever becomes available, so was just curious if any of the above serial ranges would "more correct"? Admittedly, other than serial number, I don't know if there are physical differences, so any input is appreciated.

Looks like it might be a 20" bbl but it has the pri charging handle.  There's no collar visible in the bbl shadow, maybe it has a 3 piece near the handguard.  If you look close at the shadow it looks like he might have a 951 or 952 on the left side.

Id guess thats pre 2005 based on the old style block Motorola, 3pt sling setup, and snap gear.  Also: holy height over bore batman

The top-rail he's using is the Knight's SR25 rail with the integrated rear sight. Wish I'd kept the one I had all those years ago; it looks the best, and boy do they fetched top-dollar!

And I agree, I think it's also a SAM-R. Those also used the Mk12 FF RAS. @MNRidesHonda has one of the cleanest SAM-Rs I know of.
