I am looking for info on mounting a Leupold 2.5 x 8 VX III on my .375 RSM. With the Ruger rings, the scope will not mount. Is there some different rings I need, Or am I going to have to use a scope with a 20 mm objective?

ruger has 1" and 30mm rings.. when you say your's wont mount, are the rings too big around? too small? too short (bolt handle hits?)...


jeffe

jeffe, the rings are too far apart for the scope tube to set down. The front bell or the adjustment ring hits the scope ring.

The Leupold 1.75-6x 36mm (objective diameter) E (for extended tube length) will work and is a better scope for a .416. 1-inch ring diameter.

Ruger does make some extension rings, but they only come as highs IIRC.

Thanks RIP, I figured it would be something like that. I will probably like the 1.75 x 6 as well or better , now I have to see if my dealer carries that scope, and if he will let me return the 2.5x8 and swap. On the same topic, I am interested in converting the Ruger rings to a QD system. I know that you can remove them with a coin, but since I work in a precision machine shop, I was thinking of something more like a lever system utilizing the Ruger threaded studs. In other words, I would machine a threaded nut with the same threads as the original, but with a integral lever. What do you guys think?

Rick,
Falcon Industries makes a set that is nice, they sell for about 50 bucks IIRC for the levers only.

You could do better making your own. Falcon Industries levers use a set of brass washer shims that go over the Ruger bolt sticking out from the ring side. Pick the thickness of brass washers that makes the lever line up where you want.

A sort of wing nut made by you would make a better QD conversion for the Ruger rings. IMHO.

if you work in a machine shop, then I would mill the action to take Talley rings. The Ruger rings will rotate and shift a little as you tighten them. The Talleys will not.

That scope won't work, <as is>as the distance between the rings (5.1 per leupold) is too short. you COULD get offset rings, but unless they are offset, it will just be money wasted.

but, there's hope.. you can either swap out the scope (5.4 or longer spacing) or have a gunsmith or machinest mill the (end towards the pad) on both rings to give you clearance.

I'm with RIP on this one. The 1.75-6x Leupold is a perfect fit on my .416 RSM. The only thing I changed was to have Premier Reticles install the German no. 4 reticle. I wouldn't change a thing on this setup. Mine is a consistent half-inch gun for three shots with the 370 North Forks and H4831SC.

THANKS FOR ALL THE RESPONSES GUYS. UNFORTUNATELY, MY DEALER WAS NOT AT ALL INTERESTED IN SWAPPING OUT MY SCOPE FOR THE 1.75 X 6 MODEL (EVEN IF HE HAD IT IN STOCK). IN ALL FAIRNESS TO HIM, I DID BUY THE SCOPE IN QUESTION ABOUT 8 MOS. AGO, BUT IT HAD NEVER BEEN OUT OF THE BOX TILL LAST WEEK. I GUESS I WAS EXPECTING HIM TO SWAP OUT THE SCOPE JUST FOR THE PRICE DIFFERENCE, CONSIDERING I HAD COME IN AND MADE A $2000+ CASH PURCHASE. OH WELL, ANOTHER OF LIFES LITTLE LESSONS!

I CHECKED WITH RUGER, THEY OFFER AN OFFSET RING SET IN THE MEDIUM HEIGHT ( WHICH WILL CLEAR THE FRONT OBJECTIVE) FOR $63 BUCKS. PROBLEM SOLVED.

FINALLY, I AM HARD AT WORK ON A SET OF QD LEVERS FOR THE RUGER RINGS. A LITTLE TIME ON THE CNC MACHINING CENTER, AND I SHOULD HAVE A PROTOTYPE SET TO POST PICS OF. ANYBODY INTERESTED?


RICK

IM interest.lets see them when youre done.BEST,kim Kimroux7@wmconnect.com

Rick,
Good to hear about the medium height extension rings from Ruger. I could use another set of QD levers too.

I would be interested in QD levers. I haven't been able to find commercial ones in quite some time.

I have been using the Warne QD rings on a .375 RSM with a 1X5X20 and a 3X10X40 and they work great and have always kept their zero.

RIP - I'm interested in converting my Leo extended Ruger rings to QD with the Falcon Industries levers. I've googled Falcon Industries to death and can't find contact info or anyone who sells these levers.

Do you have any contact info on the company?

Thanks

Falcon Industries makes accessories for the AR-15 type rifles. They do the Ruger levers as a sideline.

When I originally bought from them I had to call and ask by telephone. Couldn't find the levers listed on the web site. They shipped them to me within 6 days of the telephone order.

Have a look and see if things are still this way.

I would be very interested in then as well

I went the LEU ringmount route on an RSM. I phoned them directly and they sent me a front offset. It has 4.675" ring spacing.

I've made two purchases of the levers from Falcon. It was hit and miss as they were no longer regular production items. They are okay but there is nothing wrong w/ using a coin or knife on the standard Ruger ring nuts.

GVA

I talked to Falcon Industries today, they sold the part of their business that was making the levers. Sold it to a company called Tennessee Gun Parts, not sure if the levers are still in production.

GaryVA - did you use the Falcon levers on Ruger rings, or on the Leupold offset rings that you mention?

I have the Leupold rings, and I'm wondering if the Leupold QRW levers will fit the Leupold Ruger rings.

I called Tennessee Gun Parts and he was not sure what he had or whether he even made the part. Said Brownells and Midway carried them. Checked both of those places and nothing. This looks like it may be a dead end.

It looks like the Warne QD rings are the only out of the box option for QD rings on an RSM. Can anyone confirm if a Leo 1.75 x 6 will fit on an RSM with Warne rings?

Also, I noticed a few posts mentioning a Leo 1.75 x 6 E (extended tube). Is this really a different model than the regular 1.75 x 6? It isn't listed on Leupold's website. If it really is a different model, what is the Leo part number, and what is the max ring spacing?

Thanks.

Well, sorry my info on the Ruger levers was old. Hopefully they will become available again.

gusbus,
Yes, the newer 1.75x6E is a different, longer tubed scope than the old 1.75x6 version of the Leupold.

The 1.75x6E will allow a maximum ring spacing (outside max edge distance of rings) of 5-3/8".
The corresponding measure for the 2.5x8 Leupold is 5-1/8".

The Warne QD-lever Ruger rings are so wide on their bottom, forward side (they flare outward there) that they would require a 5-5/8" scope tube distance. This can be spanned with the 1.5x5 Leupold, but not the 1.75x6E nor the 2.5x8 leupold scopes, using warne rings.

However, the standard Ruger rings have a thinner and non-flared profile and they will allow, just barely, mounting of the 1.75x6E Leupold within the 5-3/8" limit on scope tube. It is a very tight fit that way, just barely possible.

The CZ 550 Magnum in .416 Rigby allows use of even the 2.5x8 without the offset rings that would be needed to use it on the RSM.

And we now know that Ruger offers offset rings in medium height for use on their rifles. Falcon Industries levers would be handy there.
Or a skillful machinist could make a wingnut and combine this with some brass washer shims to make the wingnut line up as desired when tightened down. That would be better than the vertically split Warne Rings for the Ruger.

I have never heard of anyone shearing off the recoil stop on the bottom of a Ruger ring. Can't say the same for the Warne:



Above is Bill C's result with a .458 Lott RSM and the 1.5x5 Leupold in Warne rings. Shite happens.

After he posted that, I found a bunch of the Warne QD-lever rings for Rugers on sale in the "Bargain Barn" at Cabela's here and there across the country.

RIP,

I have been going through the same thing with a RSM that I have. FYI I phoned Leupold and they told me they do not and have never made and Extended Tube Model. A guy on ebay had a "E" model advertised and when he measured it it is the same as the new 1.75 X 6 I just ordered.

As to the Warne rings I have the older Premier Rings that are one piece and have never had a problem. I called Warne and of course they do not make them any longer. The set I have are also low models that they do not make any longer.

I have a 1.5 X 5 that has gone cloudy three times on my gun. And yes I moved the scope all the way back as not to be on the gold ring and torqued with a torque wrench to 15 Inch pounds.

Tradewinds,
Don't buy any CZ .404 Jeffery just yet!!

As for the Leupold info, that is slightly bogus but understandable bogus. You talked to newbie staff member at Leupold. The 1.75x6E was hailed as a godsend when it first came out. I would have to research that to say anymore, except, I guess they did away with the shorter scope and dropped the "E" designation, just making the current one the same as the "E."

I seem to have no problems with the 1.5x5 on the RSM, don't know why you got a bummer result repeatedly there.

RIP,

What do you mean buy "Dont buy any CZ 404 Jeffery just yet" ? I am still thinking about what to buy. But I will call Whitakers soon to see what they have in stock. A friend my sell me a Dakota .416 Rigby at a real good price.

I bought a new 1.75 X 6 just a week ago and it will not fit on my RSM .375 you only have about 5 1/4" of straight tube and it looks like you need 5 1/2".

I am going to try and get Leupold to trade me for a new 1.5X5 or buy another one. It really works good with the old Premier Low mounts.


Mike

Tradewinds,
Check out the .404JCZ thread that is hot and heavy now.

I have a 1.75x6E Leupold and it has 5-3/8" ring space. That is all I can say, but that is for sure.

Wow, thanks for all the great info. Looks like my options are down to a Leo 1.5-5 with Warne QD rings. Has anyone had the Warne rings fail on a 375?
