Looking at the serial number on the piece of tape, you'll want a Wylie receiver to match the case. You'll also need an XTSP Mk13 trigger for your Mod 5. Good luck with hunting one of those down, I don't think that Tom at XTSP makes those triggers anymore, and now they're quite rare to see (and they currently sell for about $500+).Well I’ve been sitting on a mk13 kit for awhile because of other projects and funds. I have been debating if I was going to go Rem or Stiller action. I have a magnum Long action already but my kit came with a IMUNs instead of a MARS. Well today I realized that my case wasn’t completely scrubbed from Thoroughbred.
I guess Stiller it is, gotta match the case.
Edit: With that anyone have a mk13 trigger that doesn’t cost 2k?
Congratulations on acquiring that stock kit, and it's definitely one of mine! Unfortunately, it appears that a previous owner painted that stock. Crane didn't paint the bedding and exposed fiberglass in the inletting. Additionally, if you look at the chips in the left side of the forend, it looks like they have been painted over as well (this is what it looks like in the photos, you'll have to verify this). The chips would have been from SEALs using the rifle in the field and at the range. If the stock was painted before leaving Crane, the chips would be through the paint, not painted over.I’m looking for a bit more information on a Mod 0 stock I recently purchased, it seems like the stock was painted over shortly before leaving crane. The bedding material and areas that would be “exposed” fiberglass are all coated over, any help or insight would be greatly appreciated!

Is this the “R” you’re talking about top left?Looking at the serial number on the piece of tape, you'll want a Wylie receiver to match the case. You'll also need an XTSP Mk13 trigger for your Mod 5.

The $2,000 triggers are the Geissele Mk13 triggers, which were used on the Mod 7's. You need to be very careful with these triggers though, unscrupulous Gunbroker sellers have these Geissele Mk13 triggers available, but they're DRMO triggers that are KNOWN to have issues! But, those sellers won't tell you this, they just want your $2,000. I've probably sold about 2 dozen of these Geissele Mk13 triggers over the past 2 years (helping a friend sell the ones he got from Geissele), and they used to be priced at $2,500 a year or 2 ago. None of the triggers I've sold have been surplus/DRMO, all of them have been new in original packaging and acquired from Geissele.
Additionally, almost all of the triggers that I sold have an "R" laser engraved on the housing, which stands for a revision that Geissele made to these Mk13 triggers. The DRMO Geissele Mk13 triggers being sold by shady Gunbroker dealers don't have this revision, and that's one of the reasons why those triggers had failures and ended up at DRMO in the first place! So, if anyone here is looking to purchase a legit Geissele Mk13 trigger for their Mod 7 build, please make sure that you purchase one that's been acquired from Geissele, is new in original packaging, and has the "R" revision marking on the trigger housing. Don't risk spending $2,000+ on a faulty trigger that might break or fire a chambered round with the safety lever, buy the trigger from a trustworthy source.
If you’re using a factory R700 action, have you opened the holes up to 8/40?Hey fellas, got a MIRS rail for the MK13. Wanting to get some opinions on what the best torque settings for all the screws should be to keep it from coming lose during fire. Mine has come loose during a range day roughly after 10-15 rounds. I’ve tried using some blue loctite and even Rocksett, but neither seem to keep it from coming loose. Any suggestions on what I need to do to keep it locked down, maybe red loctite?
If you’re using a factory R700 action, have you opened the holes up to 8/40?
Yes sir, and I missing anything? I tried using 35in/lbs on the torque with rocksett and no luck. Should I use a red loctite?If you’re using a factory R700 action, have you opened the holes up to 8/40?
Also what about the torque specs for all the screws?
So this being a MARS rail, would the instructions apply to my MIRS rail?
Should be the same. Main thing to note when installing a MIRS is the tensioner screw (#3). After installing the rail via the top screws, you need to adjust the tensions crew so that it barely contacts the receiver and then stop. You do not want to over torque that screw.So this being a MARS rail, would the instructions apply to my MIRS rail?
Excellent comparison, thank you very much for posting the pics and information for everyone to see! It's great to see some of these minor changes to the stocks because it helps protect the collector value, history and provenance of the original Navy SEAL used Mk13 McMillan stocks! The new stocks are 99% correct, so they're perfect for a clone build and no one can tell the difference between these new stocks and the military used stocks (unless you have a tape measure and the knowledge about the differences between the stocks).For those considering one of the McMillan mod 0 limited edition stocks, I wanted to share a quick comparison between an issued stock and the “new” production run.
There are a handful of subtle differences. The good news - All of these are cosmetic and absolutely do not impact the function of the stock!
The issued stock is an early grey. I unfortunately do not have an issued tan stock to compare this against:
1. Profile view: The overall length of the new production stock is slightly shorter. The texturing extends a bit further on the new stock, but otherwise everything else lines up.
View attachment 8538900
2. Top down view: This is where most of the differences are apparent.
The forearm rail screw spacing and depth varies between both stocks. The early grey has the unfinished rail, possibly driving the difference in spacing. You can also better see in this picture that the new production stock is slightly shorter.

At the rear, the action and bolt relief cuts are a bit different. This is purely cosmetic and does not impact functionality.

3. Bottoms up view. Other than the forearm rail screw spacing, the remaining difference is the escutcheon used for the third action screw. You’ll likely want to have a gunsmith add a recess similar to the issued stock for the bolt to sit flush. The Frankensteined “CMP painted” guns released recently also do not have this recess, so it may have been machined later at crane.

Fantastic comparison, thanks @Werk125

The forearm rail screw spacing and depth varies between both stocks. The early grey has the unfinished rail, possibly driving the difference in spacing. The action pillars are closely aligned in the picture below (causing the new production stock to appear shorter). I’ve since resolved the reason for this further below.

Update: Upon closer inspection, I confirmed the new stock is not shorter; rather, the inlet is slightly forward. When aligning based on the buttstock, rather than the pillars as I did above, it’s much easier to see this.
