MTC Viper Pro Tactical

It should say somewhere in the instruction manual what the true magnification setting is.

But here is some very interesting, albeit not very well known knowledge: On SFP scopes if you dial for elevation, the reticle center + is showing the correct aimpoint at ANY magnification! Yes you read that right! (Of course the subtentions (the mil stripes) are not working correctly if not set at the true magnification but the center of the reticle IS always correct!
In other words, if you dial you can always use the center + as aimpoint but not the holdovers. (The holdovers only work at the true scope’s magnification)
But again, you HAVE to dial each shot for the correct bulletdrop at that target range. 

So, I have the MTC Viper Pro Tactical 3-18x50mm.



I usually use fixed magnification scopes.



One thing I do not understand is how to use the SCB2 Reticle. Specifically, as the scope is zoomed, each graduation means something different.

Is this correct at 3x or 18x?

Found this on AOA’s site. Description there and elsewhere say the turrets are .25 MOA per click.

This scope is a Second Focal Plane. You can't use the reticle reference mark at any zoom unless it is at the calibrated magnification. If the reticle is calibrated at 10x for a mil the adjustment or reference mark should be true. When you zoom in or out that measurement is not the same/untrue. That is where the First Focal Plane comes in it doesn't matter what magnification. At any magnification, the measurement adjusts to the zoom...


Does this make sense? I just started my weekend and I'm tipsy.

To answer the question, the hashmarks or subtentions are likely inaccurate at both 3X and 18x. As stated above, they are accurate at a specific magnification which is rarely at either end of the zoom range. As mentioned, 10X is common. I can't seem to find this info online. I have one of these in another zoom range, but sadly it came mounted on a rifle from AOA and no manual was included.

Where does it indicate whether this is an FFP or SFP scope? I checked a few sites when I found the photo explaining the reticle and it wasn’t specified. 

My MTC is also second focal plane. for what it's worth, i am not at all happy with MTC scopes. It's the softest muddiest image of all the scopes I own.

Boy you said a mouthfull. Why in the world would they use a mil reticle and MOA turrets - and then say it was designed by shooters. HA!

Here is what I found from the manual on the Krale website re what magnification the SCB2 reticle is set for:



And it is a SFP scope.

I laughed out loud to read "milliradian" "international standard of 3.6" at 100yards" (rolfmao!) and MOA,. this is like a true basket case!

A milliradian very well may be that, but it's metric so it's really;

the definition of the milliradian where the arc length is defined as 1/1,000 of the radius. A common adjustment value in firearm sights is 1 cm at 100 meters which equals 10 mm/100 m = 1/10 mrad.



It's a european company, made in China, why isn't it all metric?

So at what distance do you suggest the gun be zeroed.

Well, that depends…
What I do is enter all the ballistics data in Chairgun (a windows ballistics app) and set the killzone as 1 cm. (10mm, a little less than 1/2”, so if my range estimation is slightly off, the pellet will impact no further than half a centimeter (5mm or 1/4”) up or down from the aimpoint). Then if you select optimum zero in the app, and look at the graph of the range vs holdover in Chairgun you’ll see a curved line (the pellet path) and it intersects at 2 points with the sight line. These 2 points are the near zero (NZ) and far zero (FZ). You can use either of those 2 ranges to zero the gun. (doesn’t matter which one to use, the outcome will be the same!)
The app also tells you what your “zero range“ is. Say your NZ and FZ are something like 18m and 29meters, the zero range will be something like between 14 and 33meters. Meaning if you dialled your zero on the scope and use your center ampoint (+) your impact will be no more than a maximum of 5mm high or low, if the quarry is in that zero range. (between 14 and 33 in my example).
