So where's the instuctions for this? Just got one and what's the USB port for? I'd have to say I'm pretty disappointed with it at this point. A simple Manual would have been nice. Or even a link to download one.
EDIT:
And after some searching? I figured out it's to recharge the batteries. More searching and I can remove the picatinny mount. Guess I'll have to print something to replace that as I'm not fond of set screw clamping it to my breech.
