Hello all. I just created a new account here (previous account was shared between a former friend of mine). He made some rather daft comments on here before so I've decided to part ways and post under my own private username.

Anyhow, a few days ago I ordered a Schmidt Bender PMII 5-25 with locking turrets and tactile clicks from eurooptic.com. Double-turn is included with all 5-25's now I believe, so that's standard. (http://www.eurooptic.com/schmidt-bender-pmii-5-25x56-l-p-p4-fine-mrad-mtc-lt-ccw.aspx)

I received it today, mounted it and logically wanted to run to near bottom of travel since I will be zeroing @ 100 yards and am utilizing a 45 MOA base.

What is interesting is that the reticle is moving even when the set screws in the turret are loose (and even completely removed). Windage, no problem. Elevation, moves just like they were normally torqued down. I tested this with a white piece of paper with a dot drawn on it @ 25 feet away.

Now, the manual that comes with this scope is old... it pertains to the previous-gen knobs. Their website(s) are no help either as they simply haven't updated their manuals for these newer models (that I have found anyhow). I own a previous-generation S&B also, which requires the one pull up until the o-ring is visible, then you zero the dial(s). The current generation knobs don't come off, or slide up, or anything. They even still click when the set screws are backed off, which I read is normal (they click even though no adjustment is being made to the reticle). For the record I am not a fan of this at all. If I feel a click, I expect the erector to have moved. If I don't and it's smooth, then I know the cap is slipping and no adjustment is being made. You basically lose this ability with the current-gen S&B. Technically, in a proven working scope like this you'll always wonder if the set screws are truly tight and are actually adjusting the erector, since they click no matter what.

I will of course be calling S&B in the morning, but has anyone else experienced this issue? If it truly does turn out to be faulty (which I wouldn't see any other way it couldn't be) then I would be rather disappointed with S&B's QA department! The only thing I can think is that the turret cap is pressed too tightly on the erector rod, or the "dummy" plastic set screw in the third set screw hole was lodged in there too deep from the factory.

Simply stated, a $3729 scope should be capable of zeroing out of the box!

I will report back what S&B suggests after I talk with them.

Thanks in advance,

Lee

Why not just call Europtic? Alex is a great guy to do business with and very informed about his products.

Yeah, I could. Alex is indeed a great guy and knows a ton about all of the glass he carries, but I just like talking to the "tech" guys directly.

Interestingly, I talked to Jerry at the Virginia service location this morning and we got it fixed! This might be good information for anyone else with these latest generation turrets and am experiencing the same issue as I was.

As you can see in the picture below, there is a hidden set screw. Two set screws are user-accessible and the one pictured is covered with a plastic plug. Jerry informed me that this screw is probably ran down too far, thus still engaging the erector when the "user" screws are backed out. The hidden screw is between mil marker "10 and "9".

I wouldn't suggest trying this until speaking with someone at S&B first as it could void your warranty. Jerry gave me permission for this one simple task and only this one task. Basically you need to very gently remove the plastic pin in front of the hidden set screw. It will have to be drilled out most likely. After removing it, you can back out the once hidden set screw like the others, but no more than 1/2 turn from it's bottom position. Jerry warned me that if the turret caps come off of the new models, it's a whole world of trouble. 1/2 turn should prevent this from happening while the "user screws" are loose.

After this, adjust the scope as normal. I tested and it indeed worked great. I will be applying Loctite 222 to the set screw that was once hidden.

In summation, the hidden set screw was ran down all the way to the erector spindle, which was causing reticle movement even when the two user-accessible set screws were backed off.

Windage didn't have this problem, so it was left alone.

Thanks Jerry for the quick fix!
