Rifle Scopes Schmidt Bender MTC Turret

Re: Schmidt Bender MTC Turret

It may not have been at mechanical zero out of the box. No clue why that would be though. Zero it on the rifle and see.
 
Re: Schmidt Bender MTC Turret

I have one but with standard turrets. It should be total adjustment of 27.3 mils.

They had mine set for a couple mils of down adj and the rest up when I got it. With a 22MOA base I had to go several more mils into the up and then I loosened the set screws and zero'd the turret and drum. Now I get 1 full turn of up (14 mils), then the second turn indicator shows and then I get 8.5 more on the second turn. So I loose 4.8mils of the 27.3 adjustment range because I don't have a enough MOA base on it. It goes out to 1000y now so no need to try and find a 40MOA base right now.

Is your turret flush before you start your turns. What direction are you turning? I ordered counter-clockwise turrets to get CCW rotation to go up in elevation. Without specifying CCW, you will probably need to crank clockwise to go into the "up elevation" and make your second turn ring pop up.

I am no expert, but it might be worth looking into.

Re: Schmidt Bender MTC Turret

So far the total travel I can get out of the two-turn MTC-tuerret is 9 mil. I went on the website Trigger Monkey recomended and I am not sure what they mean by "roatating the slot in the tuerret" so that the slot is to the right when the tuerret is at zero.
 
Re: Schmidt Bender MTC Turret

After evaluation it was determined that the turret is malfunctioning. I am sending them back to Schmidt and Bender. I actually purchased two units at the same time and both turrets are doing the same thing. They are locking up at 10.5 mils right at the time it starts to lift the second turn indicator.

Thanks for the help

Re: Schmidt Bender MTC Turret

I would bet the odds that "both" MTC turrets are malfunctioning is very rare...

Did you reset the zero stop? I would bet once it is zeroed it will work ?

The chances you got 2 bad scopes out of the box from S&B are rare to none at least in my experience.
 
Re: Schmidt Bender MTC Turret

Chances are very small that two scopes have the same problem. I'll bet it's a simple adjustment of the zero stop and moving the erector to the center. Before you ship them anywhere, I suggest calling Mark at S&B/USA and have him walk you through the adjustment.
 
Re: Schmidt Bender MTC Turret

The chances are slim and none and what makes it even worse is that I needed one of the scopes last weekend. You can actually loosen the set screws so the MTC knob was not even moving the adjustment for the erector and you still could only turn the knob 10.5 MILS. On one of them it never would go past that point right when it started to lift up the second turn indicator , on the other it went past it intermittently. I talked to Mark at Schmidt and Bender and he didn't seem to have any problem believing it. There is nothing wrong with the scopes but as hard to believe as it is, both knobs are malfunctioning. I guess I still could have used them because I only need 8.6 MILS to get to a 1000 yards but I didn't feel like I should have to do that when the scopes are new. Once I receive them back from Schmidt and Bender I will let you know what they said.

PS - I am familiar with the fact that the erector could be at the extreme of top or bottom. With the set screws on the knob loose it shouldn't matter where the erector is, but I actually recentered it. I have one of the 5-25 with the older two turn knob that has the yellow indicator on the window.
I printed the adjustment information off shooting voodoo.com, Schmidt Bender double turn zeroing instructions for the MTC knob when I had a problem.
 
Re: Schmidt Bender MTC Turret

I sent both scopes back to Schmidt and Bender and they agreed that the turrets were not functioning correctly are going to replace them both.

Another thing I failed to mention is that scopes had consecutive serial numbers.

Thanks for the assistance.
 
Re: Schmidt Bender MTC Turret

Well its been a little over a year since I posted the issues with the MTC turrets. I noted a little skepticism in Franks post to if I actually knew what i was doing. For the record I own eight 5-25 PM2 Schmidt and Benders, 4 with the conventional turrets and 4 with the MTC turrets. I had the initial problem with the two MTC turrets not going into the 2nd revolution, then I had two elevation turrets that were engraved incorrectly and one MTC turret that when you got past 9 mils you were not able to feel the positive .1 clicks. I was told by S&B that there was an angularity problem between the turret and the ratchet plate. As of today I have had two scopes down for three months waiting for turrets. S&B has acknowledged the issue, starting to get annoyed at the fact of having $6,000 worth of scopes that are not useable, or at least not to my standards. I know I am not the only person having problems with the MTC turrets because when I talked to S&B I was infomred there was a number of scopes watiing for turrets. Last three digits on the scopes ser# are 831-791-793 and 798. This is one of the turrets that is engraved incorrectly, when it's on "0" it indicates almost .2 of a mil.

In this particular instance couldn't you just loosen the set screws and twist the turret to read "0"? I have 2 S&B double turns and either will allow me to loosen the set screws and adjust the turret cap to read"0".
 
Re: Schmidt Bender MTC Turret

No, in the standard DT knobs you would be able to simply slip the knob back to zero. However with the MTC turrets there is a clunk plate on the inside of the cap that is supposed to index the heavy clunk with the whole mil marks. If the engraving is off in regards to the holes that hold the clunk plate in then you get clunks that aren't on the whole mil, like above. I've seen them half a tenth off, maybe a bit more but never that bad, good luck with everything.

Mine is .1 off as well.

Did you send yours into have it redone or anything?

Curious to know Northlands question as well

I have the same scope discussed in this thread with (last-3)serial# 433. It is not as bad as some of the previous discussed (I hope!!), however its in between tenth mils and I am not the original owner. Its been zeroed to the previous owners rifle, as I am waiting on a rifle build and then I will mount this scope. This is my first S&B and honestly I have not taken the time to read a thread I tagged on how to set the zero.

So I guess what I am saying is, I dont know how much it is off!!!
 
Re: Schmidt Bender MTC Turret

As Trigger Monkey pointed out, the scope is on the zero detent in the picture. Every whole number has a signifigant detent and the tenth mils have a miner detent where you can just feel the click. So if the engraving is off it is not adjustable or correctable other then by getting a new turret cap.

Correct. Did you get a new cap or just leave it alone?
 
Re: Schmidt Bender MTC Turret

Several months ago I sent my 5-25x with MTC turrets back to S&B to have the turret "caps" replaced. The elevation turret markings were misengraved and the dial was off at the milestone click. There were a number of people with MTC turrets like mine, both 5-25x and 3-12x, that needed replacement. Furthermore, the windage clicks were just mush and needed work. As I recall, it took about 6-7 weeks for the scope to be returned. It went to Germany for the repair.
 
Re: Schmidt Bender MTC Turret

<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: bwo6.5</div><div class="ubbcode-body">I have been waiting three months for two new turret caps. </div></div>

Im curious to know if this issue was ever resolved and if so how things turned out.

Forgive me in advance, I have no experience with S&B, however I recently have taken possesion of (2)3-15x50 w/MTC and both scope's elevation indicators are in between 1/10 mils. In addition, when I rotate the elevation turret from zero to 1/10 mil it will never turn through the individual 1/10 mils, for example it jumps to 2/10 or 3/10 and then I have to carefully bring it back to 1/10 if that is what is desired.

Is Germany the only route to take for this type of service? I dont even have any of the warranty paperwork since I am not the original owner.
 
Re: Schmidt Bender MTC Turret

After nine months Schmidt & Bender sent me two MTC turrets that were engraved properly. I was expecting to get them within 3 - 4 months, but nine months is even a long time for Schmidt & Bender. It wasn't a huge inconvenience since I own a number of the 5-25's. Putting the new turrets on solved the problem and its all good now.

Re: Schmidt Bender MTC Turret

interesting. Its odd that you were so "unlucky" i guess.

as with everything usually when people have kit that's working properly they never report it as such.

My MTC 5-25 is perfect. I'll be getting the new 3-20 unicorn scope whenever that comes out. I think it has the new locking turrets if im not mistaken. Hopefully there aren't as many problems with those.

As far as MTC turrets "jumping" clicks for lack of a better term, mine does that but i think its due to the MTC "clunks" being a bit stiff... once you disengage the clunk the amount of torque you previously required to disengage the turret is still present and then you obviously pass a few 1/10 mil marks that require less torque.

Im hoping this reduces with time as it is slightly annoying to always have to go back.

Has yours “smoothed” out. Mine hasn’t. Still very tight and clunky. This S&B is mounted on a PRS/Pred rig. The deep “locking” clunks are super tight. Find my self dialing over on other rigs from training myself to do so on MTC
