Great responses - especially the reference pics - that is too cool.

I ordered A107s (1.125) NF rings for my NXS 5.5-22x56. Both are in the mail.

I guess I won't really know until I test it out how the objective bell will sit above the barrel - I can always return the rings for a higher set if this doesn't work out on this rifle:

I don't know the NF model number, but here's info from the source re 1.5" rings (sounds like small variation b/t Combat Commands).

For flat rail weapons like Mod7 and Mod5 with the iMUNs, then use 1.5” rings or if LaRue the 1.535”. Depends on the user and which SB PMII scope you use or which Component Command you want to copy. Most long range clip-ons are 1.5” centerline. The ARMY wanted 1.535” as that was SOPMOD/WPNAC height. Close enough for most applications.

For drop down rails, we used the 1.285” Larue or the 1.25” OPSS/AWP. These LaRue mounts were upon Gould’s insistence and for the most part I think the guys were happy with them. LaRue LT111 and LT120 or OPSS/AWP 1.5” rings or 1.25” rings.
...I may ping him next week about the obscure engineering topic of centerline daytime scope + NV optic alignment, just out of curiosity...

One note re the LaRue LT120 mount as mentioned in the context of what I suspect is a late Mod 5 or maybe a Mod 7:
https://www.larue.com/products/larue-tactical-qd-scope-mount-lt120/
"The LT120 QD Scope Mount is similar in design to the LT111, however it allows scope to be mounted lower to the bore. It is available in 34mm or 30mm rings. The height is set for 1.285" centerline of the scope above the M1913 Picatinny rail. Because the LT120 sits the scopes lower to the bore, they will not align properly with weapon-mounted clip-on night vision devices which sit at 1.535”. Additionally, it will not work with scopes that have an Objective Housing larger than 56mm which is the largest that will fit and still allow the use of lens caps. The mount has a 0 MOA built-in cant. The LT-120 will also accommodate the US Optics T-Pal with its larger turret body. The generous 2.9" ring spacing accommodates large turret blocks with ease.
...vs their LT111 mount:
"The LT111 OBR (Optimized Battle Rifle) QD Scope Mount was designed specifically for the OBR, available in 34mm or 30mm rings. The height is set for 1.535" above the rail, for perfect alignment with weapon-mounted clip-on night vision devices. There is zero built-in cant to ensure perfect centerline alignment (the OBR rifle has 20 MOA built-in to the upper rail). The LT-111 will also accommodate the US Optics T-Pal with it's larger turret body. The generous 2.9" ring spacing accommodates large turret blocks with ease."
I think Gould might be associated with the Special Forces, so a replica with the LaRue mount is an option, assuming that is correct inference re his Combat Command. My 2cts.

I believe the Ops PSR High rings are 1.125. I posted a photo of them on a Mars mod 5 a ways up.

This is another take off Army mk13 mod 5 take off scope (5.5-22x56mm USASFC spec) with issued larue rings on a mars. 3A707474-130C-4A3A-B166-197CC2B16617.jpeg

I think you might be right, based also on the pics by 0812guns of PSR rings. Maybe that was a typo and he meant to write 1.125 instead of 1.25.

Can someone post a pic of the correct thumb screw for the cheek piece in the mod 0 stocks? Mine came less screw and McMillan is having a hard time figuring it out. They said the .950 gen 1, but it's a 10-32 and the stock hole is 1/4-20.

@0812guns helped my friend source a thumb screw for his cheek riser. He can help you get one. McMillan didnt have the hardware in stock at the time.

Here is a pics of the correct thumb screws for the mk13, SSR and early DMR. As far as I know mcmillan has not had any more of the correct screws in a long time. I have quite a few extra surplus ones that I would be willing to sell.

very generous of you.

Interestingly, one of my issue mk13 mod 0 stocks had the same thinner thumb screw that has been seen on mk15 mod 0 kits. My other 3x mk13 mod 0 stocks had the thicker screws like yours.

My 2cts after speaking with Lynn at McMillan Stocks over the past few years. She said that while they make all their fiberglass molds and the stock itself (paraphrasing if not verbatim): "We use subcontractors for all of our stock hardware."

At the time I was asking about a cheek piece for the M2A M14 stock, and she said that their subcontractors require a minimum order of 50 parts to make their stock hardware. So if McMillan doesn't have spare hardware pieces in inventory for a discontinued stock that might need a repair, one may be out of luck, as they don't manufacture the stock's hardware in-house. My guess is that the knurled knobs they use on the various stocks might have changed subtly over time. The knob I ordered in 2009 (is smooth on face) like the one on the right in post #915.

Fwiw, here's a random factoid re a minor hardware change on the early McMillan A2 stocks for the Navy "M700/300" rifles circa 1995....the original cheek pieces were painted gray to match the stock, not the black color pad that they have used for the past 20 years or so. Not sure when that changed and maybe it was just for that initial order by Crane for gray A2 stocks, but just an random observation. (Part of me wants to clone the original flavor)

Top mk13 stock has (gray gel coat painted tan) and gray mk13 stock have a very soft foam like covering on them. The tan gel coat mk13 has the traditional harder neoprene type rubber, and here is a early gray SSR with gray rubber covering.

thats the screw. same one on the mk15 kits and off one of my painted mk13's. I wondered if a batch got the thinner knob or if it was just taken off something else.

Is that bottom AI long action? And if so is that to indicate the FA762SS is rated for 300wm and there were spec'd builds with so?
I dont have any info on that gun other than the mod 5 in that photo is a seal gun and the photo was taken in africa.

You’re missing a lot of the cleaning kit items, flexible chamber cleaning tool, bore guide, screwdriver kit, combination tool, desiccant pack, manual, cleaning rod.

    It has 3 ports so it's Surefires 338 brake for the FA338SS suppressor.

    I was told by Surefire sometime ago that the FA762SS is rated up to a standard magnum like 300 win mag.

    I've not seen a actual pic of the fat wrench screwdriver kit in a issued case either.Does anyone have a good pic of a actual deployment case with all the accessories intact.

    We have seen the entire fat wrench box like @USMCsean has in his case and also loose wrenches in tool kit bags with the bits inside the small 'medicine' container. We have seen the early FatWrenches with male heads and the later female head wrenches in kits.

    One of my kits came with this cheek riser - its just metal painted grey. Not sure if its from one of the early early greys or someone just pulled the pad off and sprayed it at some point.

    Thanks for that pic, given the grey paint looks like it was professionally applied - its smooth and I don't see any residual adhesive that was simply painted over, my guess is that cheek piece is probably an early original part. Perhaps painted grey by McMillan Stocks back in the mid-1990s for the original Crane order. Neat.

    Fwiw, attached pic appears to be dated Aug 1998 (ST 6 weapons), and it appears to show the cheek piece camo pattern painted exactly like the rifle, which suggests to me it was likely a bare aluminum cheek piece, since paint will typically not adhere to a rubber/neoprene surface in such a uniform way as seen in that pic. (The above pic with a painted rubberized cheek piece shows how the paint didn't stick well or has rubbed off the curved, rubberized surface). I don't know when McMillan added the rubberized/neoprene material to the cheek piece. Just an random observation re the earliest M700/300 stocks...

    My first of four Mk13 mod 0's just came home from @RWSGunsmithing . I have been collecting parts for these rifles for a while now and am completely blown away seeing the first one together and Robert's work is clean as always. He really went the extra mile on this one to preserve the original parts and seamlessly blend his work in there. Roberts done a few rifles for me and I strongly recommend him. I am very excited to see the next few rifles when they get completed.

    The rifle features an authentic stock, mirs, L lug, trigger, scope rings, and optic.IMG_3244.JPGIMG_3245.JPGIMG_3246.JPGIMG_3247.JPGIMG_3249.JPGIMG_3250.JPGIMG_3251.JPGIMG_3252.JPGIMG_3253.JPGIMG_3254.JPG

    Congrats - nothing quite like new rifle day.

    Robert built my Mod 5 - he's the best.

    EDIT: that looks great man - beautiful rifle.

    Curious to see the build. I’ll probably be sending a build or two to him this year as well
    updated the post with photos. Roberts doing my 3x mod 0's and 1x mod 3 and RedBull is doing all of my mod 5's, 7, 2. Have so many builds I want to spread them out.

    I never noticed the differences between cheek risers until you mentioned this. The two stocks I have are different as well. The one on top is bare aluminum and the one below has neoprene pad.

    Also interesting to note the different lengths of butt pad spacers just posted on this page alone

    Anyone have a Mod5/7 recoil lug they are willing to get rid of?

    Might have to resort to buying an A6 lug and having it ground to .250"

    @teufelhunden @mallen45

    I do my own work. Recoil lug surface grinding I'd have to outsource but theres a place 10 minutes from me that can do it. LRI will also (hopefully) be matching the muzzle to my suppressor once its released from jail. I'm confident in my work but that I feel should be left to Chads abilities.

    With a return stock, case and snagging an unused G658 action I'm hoping to keep it as correct as I can. I can swap a non NAV Spec scope easily, swapping in a correct lug later on is a bit harder. Hoping to get the correct one but keeping options open.

    That is impressive. Thanks for those pics....I like the markings on the suppressor too "MK11-0". (That platform is apparently where they came from).

    Underneath the neoprene, this cheek piece is painted the same color grey as the stock.
