Scope mount question help!

So I bought an 3-9x40 Tasco scope from a guy on ebay, the scope arrived fine and he said it would come with the mounting hardware which it did, but what the heck kind of mounting hardware is this?
What do I need to get to mount this scope onto a standard airgun reciever?
I am a newbie at this.

EDIT: Will these work or are they are not high enough.

Here's some pics.

Looks like the sort of rings you need to drill and tap a reciever for. The loops under the scope are do you can still use the iron sights in the scope fails.

Those scope rings looks like you're gonna need a scope rail to mount it on and the rail mount on to the receiver. I would just replace them with regular scope rings.

Hi Jan,

Those see-through mounts are useless for an air rifle, unless you want to drill/tap holes. Those mounts are intented for a high power rifle that has holes drilled for scope bases. The mount uses the holes that bases would use.

Yeah I'm definetely just going to replace them. Would the ones I mentioned work or do you think they are to low for that scope??

you got to make sure it will clear the height of the diameter of front lense and depends what gun, if it's bolt action you want to make sure you got enough space to load the pellet. For a good distance in range of accuracy the lower is the better.

Ok well the biggest part of the scope is 4.755 cm wide which is the front of it. It is going to be used on a Slavia 630 so not a bolt action that is no prob. You think that'll work out?

It looks like it's going to be very tight, perhaps email them and ask for the spec. on the height of that scope rings. Wouldn't it be better if you just get them locally ?

Hi Jan,

The Slavia 630 has a 13.25mm scope groove. The mounts you are considering will not likely work.

You could likely try the mounts if you want to check for yourself. They appear to be very similar to the cheapo aluminum mounts that are included with the Bushnell Sportsman scope. Bring your 630 to a gunshop and see if they have anything to fit. Seriously look at the Millet steel angle-loc rimfire mounts. The clamps apparently will widen to accept the large CZ dovetail. This is what I have been told by owners. I don't think you are going to find a cheap solution to mounting optics on the 630. This topic has been discussed several times on the yellow forum. Sorry...

Is that right? 13.25mm? I thought the 630 just had a standard reciever cause it fits mounts like the ones that come with the bushnell sportsview or crosman targetfinder just fine and those scopes are designed to fit standard 3/8" dovetail recievers. And I'm not looking for anything expensive, as long as the are made of metal I'll be happy.

In the past the 630/631 had 13.25mm dovetails. Maybe they switched to 11mm. That would be great! If it's 11mm then many rimfire style mounts should work. Just make sure you have enough height.

Also, check to see if your rifle has excess droop.

Alright well I just have to figure out what kind of clearance the scope will need. Can you give an educated guess as to which one of these mounts will give enough clearance fora 3-9x40 scope?

Hi Jan,

Now you really have my interest. Next time I'm at my favourite gunshop I will measure the CZ-630 scope groove with a dial caliper. I sure hope Slavia went to 11mm grooves

As to your question, I have a 3-9x32 scope that I can check. It's the Bushnell Sportsman model #72-0039. At the widest section, the front bell is almost 48mm across. The mounts that are included should work on a receiver with cut grooves, like the CZ rifles. The mount looks like pic #1. I don't think there would be enough clearance for a 40mm object lens. With the 32mm objective (48mm bell) there is only a few millimetres under the bell when the scope and mount are placed on a flat table. The scope tube will sit slightly lower when the claws are in the receiver grooves.

I think you will need the high mount for a 40mm front lens.

HTH,
Todd

Hi Jan,

Hmmm... you might want to try an 11mm mount on your 630 before ordering a new one. If you don't have a mount then maybe visit a gunshop and ask to try one on your rifle... or borrow one from a friend for a minute. The scope might be very offset with an 11mm clamp, but maybe that won't bother you. Make sure the screws will tighten and hold.

My quoted measurement of 13.25mm was from a machinist on the yellow forum. I still have to check the 630 rifles at the local gunshop. It sounds like it might be slightly over 13mm.

Hi Jan,

I'm posting my PM message here too... just in case someone else can use the info. Re-read this message because I found a bit more info for you.

I have not tried the Kwik-Site center split mounts on a 13.1mm dovetail or with a scope. They do work on a 12mm dovetail with a red dot. I just measured and there is only 10mm from the top of my HW45 frame to the bottom of the red dot tube. The difference between the red dot(25.4mm) and my 32mm Sportsman(almost 48mm) is slightly over 22mm total. I don't think these mounts will work for my 32mm scope so it won't work for your 40mm objective lens.

I bought my center split mounts in the USA when on vacation in 2003. They appear to be the same as the Millet aluminum rimfire mounts. Any Millet dealer should be able to get them but the Millet web site only shows medium height. I guess that's all that is made. Make some phone calls to your local shops.

Millet Vertical Split aluminum .22 caliber scope rings model TP00709.

The Millet angle-loc windage adjustable .22 caliber rings model TP00005 (high mount) should work for you. I have heard that this Millet mount works for the CZ dovetail, but have not actually tried it for myself. Price is often around $40Cdn.
LeBaron has the high angle-loc Millets for $32.94. The product code seems to conflict with Millet's web site (TP00003 vs TP00005) so you might want be be sure they are the HIGH mounts. I'm not sure if the MEDIUM will work for a 40mm scope. If possible, maybe go to LeBaron and have a look.
