That would be it. Someone posted the link, people commented, then the OP deleted the link and got his own thread locked, so someone called the mods out for locking the thread and then posted their own thread about the auction. It was quite entertaining until the forums went full lockdown.
I read the back and forth but did know what the link was.
I checked it out and no wonder they dont want more people knowing about it.

Mark does excellent work. My A1 he built is the best rifle I have ever owned and the most accurate I have ever shot. I’ll elaborate on my McM adjustable spacer install debacle later.

I'm on the lookout for "accessories" and "kit" to go along with my M40A1. Doesn't have to be actual items, I don't mind knock offs or items that look similar or look like they would fit.

Well, I've been wanting an M40A1 replica/tribute rifle for about 3 years. I acquired a Unertl 10x scope and M40A1 mount in 2018, but needed an M40A1 'return stock' to make the project a priority. After some gentle persuasion, a local buddy decided to take pity on me, and let me buy his loose return stock. (His other return stocks were built into rifles).

Like many of the originals stocks, this one has been painted and the improvised cheek rest that was taped onto the stock was removed, exposing the original forest camo pattern under the paint. I'll probably add an improvised cheek piece with some tan-colored duct tape to 'restore' its configuration while in service.

Interestingly, this stock has a black buttpad that was used on some of the late stocks. Serial # in channel matches bottom metal. Now I just need to find a proper "C" or "E" prefix Remington M700 receiver with matching bolt...and then decide on a builder. Here are the parts collected thus far (using a T-series Unertl scope and what is probably a TMA repo mount, and trying to keep this build within a budget):



Its not a smear stock, but I'm glad to finally have acquired an M40A1 return stock. I've been wanting one for quite some time....

this thread is worthless w/o pictures. post em up!!

Fun fact - This stock came from GA with a bipod stud above the sling swivel. I had GA remove it when they built the rifle but I wish I hadn't. It also has the black butt pad

So after accidentally putting a hydrogen peroxide cleaning solution in my eye by accident (my dominant eye even :p ) I decided to head to the range. Beautiful day and have the entire range to myself! Almost no wind, 5°C, and barely a cloud in the sky!

My 100 yard group wasn't that great but after 10 rounds I turned it into one large ragged hole :D

My 215 yard groups averaged just over 1/2 MOA. I've done better but I'm using my eye as an excuse

Just a quick question, do you have two screws on the left side of your action towards the rear,, if so, what are they, I see them on Gap web site if I blow the picture up??? Thanks. Charlie112

So after spending all morning at the hospital dealing with tests I went to the range with a friend to relax. It's nice having someone that forces you to push yourself.

He keeps saying he's not that great of a shooter but I've been arguing with him on that fact and I think today I've proven it. He brought out his Remington 700 AAC-SD with a Vortex 6-24 PST in 308 and I of course brought out my M40A1. He didn't have any good ammo, just some Federal Power-Shok 150gr... you know, the Blue Box lowest of the low. With it he managed to pull off this 4 shot group (he was so amazed as was I he forgot to shoot his 5th round).



So I had to step up my game and started thinking of all the excuses I could muster. I shot my first round and it was 2 inches high. I immediately though something was going on with my gun since I had been doing random bullseyes before this. I told him I figured I pulled my shot and took a second... and it went through the same hole. I was wondering what was going on when he looked over and asked me, "Is your scope set for 200 yards?". Sure enough I looked and the dial on my MST-100 was still set at "2". Oops! I figured I'd just leave it there and shot my last three rounds and pulled out this 100 yard group.



All in all it was a good day although the sun disappeared soon after we started shooting. We had a lot of fun and I hope we can go out again.

I call this picture "Grandpa and Grandson" :p

Fellows,
Just a quick question, I have been thinking of gathering parts for a M40 build. One thing I already have is a REDFIELD mount, short action, from my 1974 REMINGTON. Is this the mount I would need?? This mount takes the split rings you twist lock .....THANKS

Depends onn how accurate you want to be.

Real attention to detail requires a 40X marked Redfield base with square corners.

You could use a Redfield 700 SA with scalloped corners but that doesnt have as much cool factor. I am using one on my in current process build.

My already built M40 mounts a Badger repro of the 40X base.

You didnt post any pictures so its tough to answer if what you have will work.

Let me rephrase that....It will probably work, just depends on how M40 you want to be.

Thanks, I am going to look into the 40x base from badger, I will hang on to my scalloped base. Charlie112

The Badger M40 base is a good part.

Sucks I think they are discontinuing them.

It is $130 or so bucks though.

If you have a 700SA in hand Im guessing the look has a monetary value to you.

The Marines never used a Badger M40 repro in service but they did use 700SA.

Copy on hard to get.....I do like the looks of the Badger. Do you think anyone will build the M40 BASE like Badger?? I like things to look correct, or as close as possible.

Badger got the closest look but the Torx screw heads kind of throw it off.

You can find a 40X. Probably cost you $300 complete with numbered rings.

It kind of sounded like the G prefix was not part of the A1 series, but came later. But then I came across this post and that sounds like they might have been installed during repair.

Further comments welcomed.

Possible,but unlikely.
E series were the lat batch purchased for the A1 series.
