@teamjawbox @BravoSierra @titom110 thanks for the kind words y'all. Still getting situated, moving across the US and buying a house right now... 2/10 would not recommend.

That said, I have 14 foam cases that are getting glued up as we speak and will be ready to ship this week. They're already live on my website right now so if anyone wants one, now's your chance. I have 14 sets available and that'll probably be it for a couple months. Still TBD on more bore guides as well, but so long as there's demand I'll keep doing them.

ETA: Sheeit, top of the page, gotta kick it off with a photo.

If you go this route let me know how it goes.  I am thinking of doing something like that myself with a more modern scope for my Mod 0.  I was also looking at a similar Spuhr mount and the Badger C1 Max (which I recently saw in use on a late Mod 0)

Werent the originals closed cell?

I have an original and it's definitely open cell.

Open cell doesn't necessarily look like a sponge like a lot of people assume.  However, closed cell tends to look and feel rubber-like.

The closed cell holds the shape better and doesn’t soak up moisture. I figured these would be the same as the mk11 case foams which are closed cell.

I could be wrong about mine being open cell, who knows.

The closed cell is the hard foam that looks more like a plastic.

This is a late navy case. The box itself is a hardigg im3100. Foam is more rigid than the original mk12-1 cases and the cut is slightly different. Has lexan inserts like you see on the MK13 / mk15 / mk17 / mk20 cases.

I've had several early original SPR cases and nearly a dozen issued Mk12 mod 0/1 cases. For the Mk12 in its heyday, they were all open cell polyurethane foam which is what I use for my repros.

You're absolutely correct though, if you were going to make a rifle case from scratch today, closed cell is probably the better material to use. Like you said, it doesn't really absorb moisture and it tends to be a higher density material and also have a higher durometer (measure of shore hardness. higher the number, firmer the material) making it more durable and wear resistant. Closed cell high durometer foams tend to tear out less than open cell PU does too, and it's better for sonic/heat welding as a manufacturing process which is harder to do with open cell.

All that said, I don't make reproduction cases to be empirically "good" I make them to be as close to the originals as possible.

Thanks for sharing that photo, I don't know if I've ever seen that newer version before. Looks to be a little more "universal" with the way it's cut. Should be able to fit a 20" barreled upper in there no problem. I can tell by the photo though, that's almost certainly closed cell polyethylene foam.

Wow, went looking for rifle length KAC goodies, $1300?  When did they go full retard?

I guess the waiting game begins.

Dealers have started to get them in at $450.  Mostly filling pre-orders.  Call around and get on a list. There's two on the EE.  One at $1300 and one at $1700.

They dropped the price; It's $1295 now.

Just get on a waiting list. D Todd got some and operation parts had some too.

I'm on the operation parts list as of yesterday.

Black Phase tactical has centurion build Mod 1's. obviously not clone correct being everything centurion except the ff ras but centurion has quality stuff!

You may wanna fix a few things and report back.

No longer OD green. Glad to have located another part for the SPR build.

I've got something interesting in the works for the early style coated gasbuster since my upper was missing the original. Shame that no one seems to do the NP3 coating anymore, though.

you could fit a 20" barreled upper in there forsure. But the case is mk12 specific with kit contents

Eagle TAS1 Sling Swivel Adapters in case anybody is missing them. ITW and AB (AllBest) mfg 1" oval sliders, 1" Mil-W-17337 nylon webbing, properly 42-stitch bartacked to form the HK Snaphook Loop.

I could use one of these. Where did you find them?

I built a mk 12.1 back in 19-20 but unfortunately built it as a resto-mod instead of a real clone. It did drag me back down the cloning rabbit hole so now I’m looking at making it more of a clone and less of the train wreck that it is. Luckily I didn’t run too far off course and have a usable upper with a ras, cle spun Douglas barrel, Badger gas block,  aem5 and mount. I do have a few questions and a bit of an idea of what I’m thinking. Im not chasing after early production parts to build a museum quality clone due to the tax now required due to the popularity of the platform.

I think I’m going to grab a H&R m16a1 lower, my understanding is these are the next best thing to the Russian Paint lowers. I have a lone star a1 grip squirreled away I will probably use. I don’t know if I will try to grab a sopmod stock or a a1. Kinda leaning toward the a1 because it would be my only fixed stock ar.

For the lower is the colt short/long ambi selector correct at all?

My current Harris bipod uses a adm mount that I like a lot because it’s qd and ditches the stock mount to loose some weight, but I guess it sticks out like a sore thumb. Is the Arms Harris mount #32(?) been seen on a mod 1 at all or only on the mod 0?

Next question is the upper receiver I grabbed was one of the NON- C marked square forge with the numbers next to it. Are the C-AF still the most correct marked uppers. Have any of the more recent pictures from sniper comps ect shown these going through a rebuild with updated receiver markings? Not sure I want to buy another upper just to grab the caf markings but feel like I really need too. I plan to throw on a tear drop f/a like the fdny rifle.

For glass what all modern options have been seen in the more recent pictures like the sniper comps ect? just the mk5? Has the atacr been seen at all? I really don’t care for the old leupold glass and planned to go with a atacr originally. But not sure… could always go with a nxs I guess to be more correct but really like the idea of the atacr.


Trying not to derail and go too far off base. Let me know the thoughts and ideas. I have a hard time sticking to a strict clone and fit more in the gwot inspired area.

Ambi selectors are newer and seen on the sniper competition guns with both Mark 5HD and 1-8x ATACRs.

On the upper receiver, I’d personally not use a square forge.  C keyhole would work and were very common on the later mod 1’s.

I just received my FF RAS from Dennis A Todd today. Started installing everything and totally forgot to get a gas tube. . . . I am an idiot. Will post pics tomorrow when I go snag one and get everything buttoned up.

Found some MK12 scopes on GB. No idea how good of a price these are but TS30 and MK4. $2500/ea. If only I didn't need to get some parts for a CQBR... https://www.gunbroker.com/item/1002329046   https://www.gunbroker.com/item/1005284384

I put a Atacr 4-16x42 on my mod 0.. No ragrets.

For an early return scope I don't think that pricing is out of line.  He had them listed here in the EE a while back for much more than that.

I agree, particularly on the TS-30s. Those are pretty scarce, and a must for an early mod 1 or FDNY build. Looking at what round illum housing 2.5-8s go for the USMC turn-ins he has aren't all that bad either.

I was hoping that same seller might have some Vari-X III 3.5-10s to list. SPR doesn't look right without one.

Yup.  Early scopes are just plain sexy.

This is what I’m leaning towards but didn’t want to come out and say it. I prefer a bit more mag for varmints and such.

Can't decide which of those is cooler. Excellent builds.

One thing on the FDNY has always confused me. Why would he use the #36S-EX sleeve and then put an iron sight on top of it instead of just using a #38S-EX that has an iron sight integrated into it? Having the rear iron sight half an inch taller than the front has got to affect zeroing too, wonder what the MOA bias on that is

Just put a Leupold Mark 5HD 3.6-18 on mine.  No regrets either.

No idea.  Possibly as simple as he just wanted to run the scope higher and that #36S-EX was what was at hand to get it done.  

Could've just stuck it there so he didn't lose it.

I’m a clone gun guy, but at the end of the day I’m function over form as I’d not hesitate to use these rifles for shtf. I love the mk12 platform, but I wanted quality reliable modern glass. NF is always the answer imho.  I do have a 2.5-10 on my mod 1 and it’s a great scope as well.

Things got a little weird today with the mini Mod H

That Mini Mod H is sick as hell dude.

Unrelated, do we know if the FDNY Mod 1 was a Colt or GM?

Colt serial # 4804945

Question guys if doing a MK12 mod 1 clone would it be cool to use the daniel defense mk12 gas block ?

cant seem to find the badger badger ordnance one anywhere

A little birdie told me you should call Badger next week.
