M40 Build Guide

Re: M40 Build Guide

Good point. Like I said, speculation

Whatever their reason for adding a clip slot, it wasn't used.

The clipslot can be seen by the curve in the receiver on the left side. Also with the clipslot it is cut on top of the receiver for the scope mount that is lugged to fit into the receiver. </div></div>
BTW that picture in your post is badass.


Here is another pic of it full size.

Re: M40 Build Guide

The clip slot is I believe as said before, a carry over from years previously. The Corp has a strong history of rifle shooting, many of the Winchester rifles used in Vietnam were rifles used in competition. The 1903 rifles used in competition were clip slotted and every rifle used in competition by the corp since is clip-slotted, and since it was necessary for competition I suppose thats the primary reason.
 
Re: M40 Build Guide

In Senich's book 'The Long-Range War, Sniping in Vietnam' you can see the pin in all but 1 of the 4 pics of the M40 stock. Remington has used it on all of their 700 wood stocks so see no reason they wouldn't have added that same to the M40? Not alot of wood remaining between trigger inlet and mag box inlet so the brass pin is a cheap way to insure stock integrity.
 
Re: M40 Build Guide

SD, Thank you. I just do not notice them that much. Hard to see, I guess. And most photos show the bolt side.

About the Badger mounts, they come in today. They look right for the old actions. I will put on tonight. On the box it is marked Numeric S/N only. I guess this means pre prefix. Martin said that he had 4 others with rings last week. It was a special run, so might not happen again.
 
Re: M40 Build Guide - Not M40A1

The Badger mount fit the 221xxx receiver fine. I think there are 4 left, good luck. They come with correct rings, but not slot head screws. I have a pair of extra rings, if anyone needs them.

That's good to know about them fitting, as I ordered one of the sets and have it on the way. I got a set of the original dated rings and a later style base a while back, but since I found a 6-digit receiver (256xxx) to build this off of, I decided that I better get the base that goes with it and ordered one of these. I also finally found an original split sear trigger with the tombstone safety for it and got a set of the Wicita swivels, so now I'm getting to the point of needing to do the clip slot milling work (once I get the old barrel off) and then ordering a barrel.

This has certainly turned into a much more detailed replica than I had started it out to be, and will wind up costing a lot more than just buying one of the Vietnam M40 commemeratives from Remington would have. But at least when it gets finished, it *should* be about as close to an original as I can build it, for not being an original. And there is a certain pride to that, plus the enjoyment of learning as much about the originals in the process.

That said; I AM looking forward to actually getting to SHOOT the rifle, too...

Re: M40 Build Guide - Not M40A1

Mine came in today, so here's a few photos of it on the 6-digit receiver that the replica will be built on. (It's currently a .223 but you can see the other half of the project; a .308 ADL that has been modified, in the last picture)
015.jpg


017.jpg


Here's the other part of the project...

018.jpg


The Badger base is on the .223 6-digit rifle but the scope has the original set of dated rings on it. They fit just fine, and the Badger rings work great with the other late-model base on the later-model (1977 A code) rifle.

I also got in my old style split sear trigger with the tombstone safety and it works well with the .308 bolt out of the other rifle too, and hopefully will do the same after I install the short shroud on it. Now to get the receiver clip slotting milled, get a barrel and do the markings, refinish it all correctly, and open up the stock channel and round off the end of the stock...

Re: M40 Build Guide - Not M40A1

In one of Senich's books, it seems I recall a mention of Chuck MaWhinney stating that his M40 in use was painted OD green, in an attempt to help seal the grain of the stock (that and having the inner tube improvised into scope caps). I'll have to see if I can find the exact quote and provide a title and page number for reference, but yes in answer to your question.

Oh, and as for a source of the slings, I got mine from Bill Ricca so you might want to check with him to see if he has some more.
 
Re: M40 Build Guide - Not M40A1

AHA! Found it! The question about the M700 being painted green was from Peter Senich's book "The One Round War" and is part of a photo caption on page 210.

"...According to Mawhinney, "The rifle stock was painted green when the weapon was issued." (Early efforts to waterproof sniper rifle stocks in Vietnam included "sealing measures" involving the use of paint. USMC ordnance papers indicate gray or green were "acceptable colors.")" -P. Senich

Hopefully that helps answer the question. Very good book for information and details about Vietnam era rifles and history, too.
 
Re: M40 Build Guide - Not M40A1

Got to see a few pictures recently and they were definitely not Wichita, I think we are all positive Wichita was used on the M40A1, and in fact Wichita notes on their own website that it was 1970 when they received an order for the sling swivel. Anyone else confirm my sneaky suspicions, since the rifle came from Remington.

Re: M40 Build Guide - Not M40A1

Marty
Who made the wood screw type sling swivels for the 40-X rimfires installed in the butts of the CMP guns? They look like Wichita's also but being late 50'x and early 60's that sure wouldn't fit with the 1970 date would it? I have never looked at one real close or bothered to compare them to an M40A1 era Wichita. Damn always shit coming up that mess's with an 'assumption' huh.LOL
 
Re: M40 Build Guide - Not M40A1

Denis, yup I just assumed they were Wichita, but looking real hard at two different photos leads me to believe they are the same swivels used on the Remington 40X and that would be an in house Remington product I suppose.

An just the swivel the best picture I can take from the book

Re: M40 Build Guide - Not M40A1

<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: USMC Grunt</div><div class="ubbcode-body">Anybody know what kind of barrels that used when they rebarreled the M40?
</div></div>

As I understand it, they used Gary Schneider's barrels when they first rebarreled the M40. But the original barrels were from Remington's custom shop and were a 24-inch varmint barrel with flat crown and no roll mark; only the stamps at the base of the barrel on each side on the "early" ones, and ".308 NATO" on the later ones (although I have yet to find a definitive answer on what date separates "early" from "late" on that change). Gary's contact info is:

Schneider Rifle Barrels
1403 Red Baron
Payson, AZ 85541
Phone: (928) 474-2852

I spoke to him a while back about my project. Real nice guy to talk to, and I am still considering getting one of his barrels for my project if I am unable to ever locate an original one...
 
Re: M40 Build Guide - Not M40A1

I believe Gary provided barrels for the M40A1 after Atkinson Gun Co provided the originals. The Corp received an initial order of 550 M40 rifles with scope attached, and 150 without, I suppose you could surmise that these rifles were the early rifles, but its hard to say if they were all marked the same way, certainly most 300000 serial numbered rifles I have seen photos off, appeared to be marked 7.62 Nato. Breakdown of rifles procured by year, 1966-700, 67-62, 68-87, 69-137, 1970-8, 1971-1 for a total of 995. Douglas was a supplier of barrels to Remingtons custom shop, they patented the air-gaging which was huge boon for accuracyand Remington jumped on this.
 
Re: M40 Build Guide - Not M40A1

Did Douglas supply the barrels to Remington and then Rem put their stamp on the barrels? What was the size of the stamping on the ones that were rebarreled? So if I was to buy a Douglas barrel for an M40 that would be to spec as well?
 
Re: M40 Build Guide - Not M40A1

Maybe Denis, SDwhirlwind can chime in, Denis knows a lot more than I do. For many years folks thought the Heart symbol on the barrel was a tribute to Hart barrels and Clyde Hart, but both Hart and Remington have stated this is incorrect. I have seen several internet postings in which Douglas was indeed a supplier of barrels to Remington, I suppose the barrel would be provided plain and Remington would add any necessary marking during manufacture.

Re: M40 Build Guide

nomre606: Forgot to add:
The Numrich stocks need to have the barrel forarm end reconfigured (rounded off – Sanded). They come with a new butt plastic type butt pad. An Aluminum one from a Rem 721 or 725 fits better if you can’t find an early 700 pad. You will need to open up the barrel channel by sanding to get clearance. Check this thread above. It's all there.

Hope this helps.
 
Re: M40 Build Guide

Only thing with the 721/722 etc is that they have horizontal ridges with top and bottom being smooth on the aluminum buttplate whereas the early 700's have a diamond/checkered pattern over the entire plate except for the Remington logo.
 
Re: M40 Build Guide

I have four "Extra" early aluminun butt plates from the 700's, all require some sanding down of the stock to fit. If you need one, let me know.

I orderd one of the 721 (or maybe for a 725?)(any way, they list them as for 721,722 & 725) one's from Numrich and it was checkered and it fit better. Maybe they don't know the diff?

Re: M40 Build Guide

Gutowsky- Thanks for the offer, think however I have at least 10 of the checkered ones. These early ones are marked with Remington Part # 16601 along with another 1 through 4 code number lower down. Remington installed the aluminum butt plates on the stocks and then sanded the stocks and butt plates together to get a nice fit. So it is hard to find a buttplate that fits exactly. Many of mine are a bit too narrow also on another stock. Pretty sure they do the same with the plastic ones also. Think the newer stock like used on the mid 80's 700P and the ones Sarco and Numurich have sold are a bit meater in the butt then the early 60's stocks?

Some of the 740/742/760 are checkered also. Hell I don't know if there was anything set in stone at Remington back then!!!! Maybe they used whatever shit was at hand?
 
Re: M40 Build Guide

Gutowsky, my only gripe with the Numrich stocks is it seems the barrel channel is for a something greater than a varmint contour. I know several years ago, they had ADL uncheckered varmint stocks for sale that were a perfect fit. I am pretty sure someone on the Hide bought one for his M40 copy and it looked great. Dennis, kinda figured they sanded the buttplates down, I have never found two the same. Did you ever get a chance to do any research with regards to the swivels, just looking at the pictures, I just have to say they are 40X swivels nothing more.
Marty
 
Re: M40 Build Guide

Brent, some edits if you care for them
Some of the later rifles did come from the factory stamped 7.62 Nato, now that would definitely include most of the later 300,000 serial numbered rifles and those seven digit rifles purchased after 1968 in the 62572** serial number range.

Don't think the Satin scopes were marked to the rifles like the green ones were, but there were four presentation rifles built on seven digit actons, that had the last four numbers of the rifles serial number electro pencilled on the base and left side of the scope.

The swivels are not Wichita, not on the early rifles, not before 1970 anyways. They seem to be and appear to be Remington 40X swivels nothing more, nothing less. Wichita was not awarded the contract with the USMC until 1970.

Finish parked, flat black on bolt body and bottom metal, gloss black on bolt shroud, I can only guess what they may have used.

Not sure on the base and rings, I have seen pictures that were blue and many that were matte, also manganese parked.
On aside note, glad your back building one, great job on the stock it looks great.

Re: M40 Build Guide

I was just thinking:

Back when I was a young Pup, I ran several Corvettes and messed with them all. Bigger engines, wider wheels all kinds of modifications. Well, had I maintained them as Stock from the manufacture they would be “Correct”. But, that wasn’t the goal at the time, being the first down the quarter-mile was more important.

So, with the M40’s & A1’s, we can all have different degrees of correctness that fits our needs. I appreciate the information as to what was the “As Built” details on both, but, we can’t all become so particular to shun those examples that might be somewhat “incorrect”.

I love to see what others have done and have tried to encourage the “Run what you B’rung” philosophy. The best examples of correctness are awesome and maybe someday I’ll try and copy this build! Till then mounting a New 5R into a wood stock, Piller Bedding and mounting a Kahles ZF-95 has produced the most “Fun” type of M40’ish rifle. It’s fun to shoot!

BTW: 100th post! Haha!

Congrats... What 1320 times did your vettes use to turn?

Im still working on my M40 clone. I will not be 100% spec but will be as close as I can get it with the parts that I have.

I am down to the buttplate issue. I have a older PSS going into a Wododen stock that looks like an old M40 stock. However, the stock is stight/flat in the buttplate area and not curved. I have seen in The One Round War book a picture of an early M40 that looks to be flat in the same area but do not have the book here at work to reference a page number. I wonder if my best option is to find the "correct" looking plate and reshape the stock to fit the curved plate.

A curved buttplate that I just bought and hope to receive soon:

Re: M40 Build Guide

Put a thin Packmayer on that bad boy. I did one like that (guess I should learn how to post pictures, Huh.) and it not only looks neat, but takes some of the pounding out of shooting it.

Or put the metal plate on it and get a Simms Limbsaver slip-on. Still saves the shoulder on a long day, but you can take it off and still have the metal "look" if you want it. I do agree that there IS a certain leeway in even doing a "correct" M700 clone, to a degree. If these were rebuilt along the way and the original barrels, scopes, etc. were changed out while in service, to keep them in the field, then it would seem to me that any variant of that would also be "correct" for the M40. Plus, it would depend on if you are trying to clone a Vietnam M700 or a post war version. Same receiver at the core, but the upgrade program (as I understand it) had some stages in between the 1966 as-built Remington M700 and the official changeover to the M40A1 specs. Or perhaps I am wrong? And either way, no matter WHAT we do to them, they still are not going to be originals (short of buying a documented "U.S." receiver and rebuilding it with take-off parts, IF you could find them) so I guess there is something to be said for the "run what ya brung" approach, too. Although I still am trying my best to get as near to correct as I can with my own...

Here's where mine is at right now.
002-2.jpg

003-2.jpg

004-2.jpg


Mine has an ADL stock that still needs the nose reshaped, the barrel channel opened (once I have the barrel), and the last of the checkering taken off/out.
006-1.jpg

007-2.jpg


I did manage to get the checkered buttplate for it, so that part is done, and used a set of Witchita swivels for it.
008-1.jpg


The two biggest things holding me up right now are A) deciding on and buying the "right" barrel for it, and B) getting the clip slot mods added correctly. But the point is, once it's done, it will be something that I am satisfied with, and hopefully also a good shooter.
