Help Securing Scope

Just purchased a Benjamin Trail NP2 and it came with a 3x9x40AO scope. I'm having trouble making sure the scope stays solid in the rings and that the rings stay solid on the rail. I've tried locktiting all the screws and it didn't solve these problems. Just wondering if maybe its the way I'm holding the gun while shooting that's creating more recoil through the scope or maybe I need new rings? Any help you old pros can give me would be great.
 
You should be able to clamp your rings enough to hold it.there should be a small gap between the top and bottom ring,if the screws are tightend all the way and there is no gap and the scope is still slipping under recoil you probably need new rings. Two things to remember don't tighten the rings so much that you crimp the scope tube (that creates a lot of different problems ) and spring or gas piston rifles create a unique forward recoil that can flat out destroy scopes that are not airgun rated. Hope this helps.
 
Is the scope moving in the rings or are the bases moving on the mount? If you loosen the scope bases from the rail can you move the rings forward and backward? (in regards to the barrel) if so move your rings to the back of the slot they are in (towards the stock) and tighten them dowm with lock tite. Is any one aware if the np trail 2 has a stop pin hole?
 
I had an old springer that moved the same way. I used locktite on the screws, tightened it well, used an extra rail stop( not a pin) and it still moved. I purchased a dovetail 3/8 to weaver/ picatinny adapter from Amazon. I placed a dab of goop from eclectic products in the rings and between the base and gun. Clean the oil and grease off first. I then marked the position of the scope and it never moved again. The base had a broader area for the goop and several strong connectors for attachment to the dovetail groove and the rings could not move due to the base slots. My rings had been sliding down the groove 1/64th with every shot fired previously. 
 
My shooting buddy and me both have the Trail NP XL, i.e. the previous version. My scope never moves, even after taking it off and re-mounting it; just have to tighten the screws properly and it stays where it is. His does though. Guess it's a problem with the screws coming loose. I would have suggested Loctite (well, that's a brand, guess a similar product should do the trick too) but since that doesn't do the trick, this might be an issue with tolerances . Could be that the ID of the rings is in some cases just a bit too large. Piece of some kind of tape might help, or other rings.
A scope stop is not too relevant here as the slots in the picatinny rail make sure the rings stay where they are.
 
Sometime it helps to clean the contact surfaces with a good degreaser like 90% alcohol or acetone. I have found that usually the slippage is at the base-receiver interface. If it has a pin you should use it and push it back against the pin as you tighten the screws up. It might take a few shots before it settles down. Don't over torque the scope ring screws or you will risk damage to the scope. A starting point that might be around 10-15 in-ibs, But check with the manufacture of your scope rings to see if they recommend a torque.

What rings? Maybe try some BKL rings/mount. One rifle moves the scope, one doesn't (same scope & rings eh?) one really needs a tune? Some are much more violent than others, a seal going bad can really add to the hammer effect, just a thought.
I've never seen an airgun one style or the other BKL wouldn't hold solid on.
Let us know what fix ya end up with,
