Finish (of the first gun), value.
Things I would have changed:Make sure gun doesn't come new with defective and/or missing parts.
What others should know:First gun came with stock in the nice finish as seen in this ad, but missing parts and with a defective tube cap o-ring. Second replacement gun (which came really fast - thanks, PyramydAir) came with stock in dark, flat finish and missing even more parts than the first gun (but at least the tube cap o-ring was ok). There doesn't seem to be a way to only get missing parts replaced (I contacted Beeman twice, no response), so I'm giving up on this gun and will try another gun/manufacturer/distributor with better quality control and customer service. Reading other reviews, it seems to be totally hit-or-miss with this gun. Hopefully, you'll be luckier than I was.

Is there a multi-shot tray available?
no
Made in Germany or China?
Does this rifle come with the rear diopter sight as well as the notch? And are they going to available ever?
You would have to purchase a rear diopter separately. At this time we do not have an in-stock date.

The tube cap o-ring seals properly and doesn't leak. Getting about 85 full power shots. Very smooth bolt. Excellent accuracy. Nice finish and all screws were tight when I opened the box.
Things I would have changed:This rifle was an upgrade from the 2078 thumbhole rifles that were plague ridden out of the box. That being said, the thumbhole rifles have the two stage trigger which I prefer and a better diopter sight (even though it's marked in Chinese.) Also the 78A doesn't come with a degassing wrench and they are not available. Finally, I would make the length of pull adult-sized.
What others should know:The rifle would be perfect for someone about 5'7". I'm 6'0" so it feels like a youth rifle, but the thing does shoot well.
