M40A1 repo mounts and rings

[Frank Green]

So I did pm three guys that they're mounts shipped but I'll put it here so guys know the stuff is moving....

@RIGREG

@AndyK

@kft101

As I get more updates I'll message you guys.

Don't everyone else beat me up... LOL! I'm still waiting for mine and for two mounts I have to deliver personally to ret. USMC SS guys. When I get they're mounts will be having lunch together. They're only a 1.5 hour away from me.

Later, Frank

So I pm'd a couple more guys that they're mounts are shipping today.

I did talk to George at GAP as he got his mounts on Friday and he measured them etc... and said they are awesome!

 

[Frank Green]

Small oh boy…..

Guys please check your mounts when you receive them. Look on the top flat between the rings. If you get a mount that’s stamped 7393. That mount was suppose to be mine. It’s the last 4 digits of my rifles s/n.

I didn’t ask for it be done… they did it as a thank you for putting this all together and I didn’t find out till just recently.

My mounts came today along with the others I have to get to local guys/SS guys and no mounts with a s/n.

 

[Frank Green]

Well it’s pretty for sure a thing there was a fubar in shipping!

PLEASE, PLEASE check your mount or mounts when you get them for a stamped s/n. Someone got my mount is what the conclusion is coming to.

Thanks, Frank

Hey Frank, I received the mount in the mail today. It's stamped 7393.

Ok... how can I get it from you? I'll send you one of the extra's that I got. Ship it up to me and let me know what I owe ya for it.

I'll send you out another one tomorrow and I'll throw some $ in the box to cover the shipping from you to me on mine.

Has anybody confirmed compatibility of these mounts with the badger ordnance m40a1 Simrad cap? I ask cause the two other mounts I’ve tested were not (TMA and ICE)

The hole spacing is different on the BO caps. So those are suppose to be to the original spec. The ICE mounts I know for sure they don't line up. I've got one. So I bought a BO cap and modified it.

The mounts that were made that I helped do the buy on are suppose to be to the original spec for the hole spacing. I didn't double check that as of yet because the BO cap I have I modified it. I did put it on the new mounts that we all got... and the holes didn't line up on the modified BO cap so I will take a stab and say yes they are to the old spec.

A new/repro cap is in the works as well being made by the same place that we did the group buy on.

So here is a update on the mounts. I took one of the ones I got and fit it to my original 40x action that was clip slotted at the Remington factory custom shop.

I had to take off about .020" from the back side of the rear lug. I put a 45 degree chamfer on the back corners to make sure the back corners so it didn't get tight there/bind with that inside radius of the clip slot on the back of the receiver. The angle was about .050" on each back corner I did.

The mount went on to the receiver with no issues.

It did sit higher because that back tang as to how it's machined. So I did some checking and was involved with a conversation with George at GAP and a few others. The sample mount that the shop had... didn't have the bottom of the rear tang have the radius to match the rear bridge of the Rem. 700 action. I was told that that was intentional to give the mount some built in moa for the scopes to have enough elevation out to a 1k yards. Land even told me that.

If I was going to do the mounts myself... I actually had two versions in mind. One matches what we got which is the same as the Ice mounts but then I did one with the rear tang to match the Remmy rear bridge. I just thought it would look cleaner.

We think the one mount supplied was a really late version where the intentions was to true up the rear receiver bridge and then fit the mount to the receiver. It was jokingly told to me maybe we should call it M40A1.2. Rumor I was told it was Chandlers idea. I can't confirm that myself. Anyways for whatever reason... here is where it's at.

GAP is getting they're mounts reworked so that rear tang will have the radius done to it so it matches the receiver.

I took the mount for my 40x and went on a limb here myself and set it up in the mill and cut that radius on the back bottom of the rear tang to match the Remmy action. Think it's a 1.819" radius.

I like how it looks much better. So the maker that made the mounts... if anyone wants they're mounts rear tang modified to match the rear bridge. Send it in and they will rework it at n/c and return it back to you. If you want yours done... PM me and I'll get you the contact info.

If anyone buys the ICE mounts it won't come with that rear radius either. The first ones didn't have it as well and I got one of them.

Here is some pic's of the mount that I fit up to my 40x. On the edges of the mount the funny looking discoloration is from when I put layout die on it before I machined it to fit.

Later, Frank

Out of curiosity, did you or someone you know shoot the rifle and zero both before and after the modification to the mount you describe above? I am curious how much elevation change this modification induces. My thoughts are it should shift POI up significantly, just not sure how far.

No I didn't shoot it.

It's a 40x I picked up on 308w... I just wanted it for the action. I just haven't stripped it yet.

I think the POI up would be quite a bit. I can measure an unmodified one and give you a close guess how much it would be.

That would be greatly appreciated.
