I recently purchased one of these scopes from Alan at Optics NZ (springerfan on this forum) to fit to my FX Dreamline that I use for target shooting.  This was after some earlier poor results with a good quality smaller scope that actually turned out to be caused by faulty assembly of the barrel at the factory.  This was recently sorted out for me under warranty by Ron Young (great guy), and the results from our practice shoot today (below) are as good as I could have hoped for.

The scope is of course made in China, has 10-40 magnification with a 50mm objective lens and AO side focus adjustment which works down to less than 10m.  It's fitted on a set of Sports Match adjustable mounts which are themselves quite impressive.  The turrets have quite fine 1/8 MOA adjustments and I've removed the o-rings to get a very definitive click from them.  It comes standard with VectorOptic's own mounts, but they are the Picattiny style and the Dreamline has dovetail rails so I also invested in my first set of fancy (read - expensive) mounts.

So far I'm pretty damned impressed with it, so much so that I've since bought another one for my Duke Il (Evanix) Hunting Master AR6 which I'm upgrading specifically for target shooting.  The reticle is SFP, but nice and fine with regular graduations and a very sharp image.  The optics are crisp and clear  (probably not quite as good as the high end stuff but good enough for me) and the AO graduations are spot on.  It's quite large as you can see, but it's for target work, not for hunting.  I've since fitted a 100mm alloy adjuster wheel, also from VectorOptics, but this time via Ali Express.

At $440.10 delivered (discounted price to forum members) with a 5-year warranty, I think it's pretty hard to beat for this type of application on a PCP.  I'm not sure I'd risk it on a springer.
