"Arsenal refurbished". I'd like to see documentation of that.

They're on page 12 of this catalog:

Maybe some background on the photos?

Good catch TomW.

Anyone else notice some SN's? What are the odds of a rifle having a part with same SN as receiver? Probably much higher than finding a rifle with all parts matching the production logs! But to have 3 parts with SN's matching the receiver? Astronomical!

Unless faked, of course.

I added the laminated cheeks to a repro stock. purchased from John Darling. Remember him? 

The bulges were trimmed off, leaving the stock two inches in thickness. A pair of walnut blocks were then glued and clamped into place with Gorilla Glue. I worked the bulges to shape with a wood file and sandpaper. They came out beautifully, if I do say so myself. I also added the lightening holes under the butt plate.

This job was necessitated because my otherwise minty JSAR had heavy damage to the top of the butt stock's comb. The damage was really deep, looking like beavers had been at it. There was no way to repair it invisibly. My plan was to replace the butt stock with the repro and retain the original. 

John's inletting was perfect, requiring very minor fitting. After the mods, it was easy to match the finish to the front grip, which is in original condition with the cross-grain belt sanding marks still visible. I'll go so far as to say that it would be difficult to tell the repro buttstock from an original today.

The sling and scabbard in the photo are repros as I have not been able to find originals as nice as the rifle.

I see a 2.

I think you might be right, in the third photo, upside down, under the trigger housing channel.

Interesting that there are no code markings on this one. I suppose that not all butt stocks had them. 

Tenuous "facts" at best.

I believe TSMMGUY may be mistaken about the buffer.  If the buffer is quite commonly missing as it was mentioned, that means that there will be several non functioning JSAR’s with several owners searching for the buffers.  I’ve attached a picture of the part #65 “mainspring tube cap buffer assembly” with the #32 “mainspring follower”, both parts are crucial to the rifle’s function.  Also shown is the tube cap and buffer disassembled for clarity.

Wish I could find a link to the original post, but a member was wondering what screwed into his rifle's recoil spring tube plug. His photo showed that his JSAR's buffer assembly was completely missing. He also reported violent operation.

IIRC, there was also a discussion about how to tell if a JSAR buffer was missing without removing the recoil tube plug. Remove the butt plate. Stick a wire into the center hole of the plug. If the wire goes in a few inches and stops, then the buffer assembly is present. It's missing if the wire can be inserted virtually the entire length of the recoil spring tube.

Kind of a crude picture edit, but I learned early on from Joseph Scott that you want to make sure that there is 8” from center of screw to center of screw. You will find sporters that measure 7-7/8” or less.  It affects the recoil impact on the buffer if it’s not right. 

 

If the buffer is present at all, and they often are not. 

Not throwing rocks at any particular greenhouse, but these rifles are often shot out, worn out, incomplete, heavily modified and refinished. They still sell for big money. No wonder the rifle's design gets a bum rap, when condition is the real problem.

Nice original examples are rare indeed. I lucked into a B series JSAR in in original almost perfect condition, with a mirror bore. It's perfectly accurate and completely reliable. It has none of the violent action of the worn-out guns. It's a very different beast from what is usually offered for sale.  

Does Prestigious add the lightening holes under the butt plate? Could stock laminations be added as well? These are what would make a repro just that much more accurate.

Great post!

Doesn't look like an M1903 barrel star gauge, either.  

B3222 photo #12 shows the bayonet rivet. These were never serial numbered by the factory or the Marine Corps.

Yes, this is true - I got an NRA sporter stock from him that I was not happy with.  A good friend sent him some JSAR samples and metal with the intent of Murray producing repro wood.  Much time elapsed before Murray returned the samples stating that it couldn't be done.

Yeah, I ordered a repro M1941 butt stock from Murray's. He sent a beautiful piece of wood that had the correct exterior dimensions. It was not inletted and was therefore useless as I lack the skills necessary to complete the job. Murray explained that he didn't have an original stock to use as a template. A full refund was eventually made, but I never did figure out the object of that exercise. I was out shipping in both directions.

Welcome!

The magazine cover spring should be a leaf of spring steel rather than the coil spring shown in your photo, It's part number 31 in the schematic and list shown here:

I have bought from this seller before and have found them to be honest and diligent. Looks like the flared end of this pin might be slightly bent but that might be a trick of the camera angle.

SN B2752 seen on GunBroker. Missing rear leaf sight, drilled and tapped with some filled drill holes. No bayo lug. Little spring steel tab missing for the front cross pin. Butt pad appears old/hard. Metal mostly worn, pitted, showing rust in places. Rear sling swivel incorrect. Current wood not too bad. Hard to discern all screws, but some questionable.

Looks like a stock lamination is about to separate, too. 

Couldn't find it. A link would be helpful.

I'd think that the recontoured receiver would pretty much preclude a restoration to the original configuration.

I thought it would go higher than that. It is an interesting and historic piece.

HMMMM - If that was issued to the Marines, it either saw no use or was redone after? Just IMHO

This rifle shows none of the typical Marine front and rear sight mods. It doesn't look like a gun that saw hard service in the South Pacific.

"New old stock condition" my foot.

The tube "stop" bar has been present on all the sporters which I have encountered. Most which I've seen, have no screws holding the "stop" in place...only wooden plugs recessed flush with the surface. Sometimes it looks like they attempted to match the wood grain and sometimes it appears they didn't even try to match the stock's grain or even come close. I have seen a few sporter stocks which have the plugged hole on only one side...I couldn't find a plug on the other side.

Thanks!

I don't think this is about the accuracy of the details. Rather, it's about one man's journey to a greater understanding of a classic design. His gunsmithing experience of many years aids him in this. I learned a few things, too. For instance, after owning and shooting a JSAR for the last 30 years or so, I didn't realize that the safety locks both the trigger and the bolt.

Very entertaining and informative video linked below.

Old thread, I know. Here's a pic of these stock markings found on the internet.
