I would like a gun, but not that gun. Gunpowder has been around a long time. Something simple and robust with a long barrel like a mosin could be modified to work as a rifled flintlock if cased ammunition is too hard to replicate. People made some pretty intricate metalwork though, if you happen to be in a place near a jeweler, you might be able to get some cases made.
Maybe have a blacksmith reverse engineer a rifle, get some folks behind you and overthrow some lords. Kill the old money, set up a government for the people, keep manufacturing as many simple rifles as possible, sail to america and give them to the natives and tell them to shoot at boats before they get too close.
Problem is, I don't speak any of the useful languages. So maybe the Moog and ten bottles of cinnamon would be better. At least I could entertain myself until I die of dysentery.
Motorcycle and Moog. The motorcycle will take me to a forest, and then the parts can be useful for making sharp stuff or tying things or starting fires and I'll just camp forever and play rad tunes. Make a cart with the motorcycle wheels to carry animals or foraged supplies, build a cabin and just tinker forever.
Might get lonely out there. Should probably try to pick up chicks before my hog runs outta crank.
Edit: wait how do I carry a keyboard on a motorcycle

Freaking epic. Make sure the Taino get them first. That'll stop the whole Atlantic slave trade before it starts!
Pneumatic (air) guns can be hard hitters without any black powder. You can load them with self-made particles. I'd better prefer them than standard guns, even old ones.
