Why is that iffy?
Barrel length has nothing to do with accuracy and if you're concerned that it is a stock barrel, well, I'm sure they managed to manufacture a few "better-than-average" ones and it looks like I got one. 
The barrel is free-floated and the receiver and trigger group are from a 10/22T which probably helps to account for the better-than-average accuracy as well.
I don't normally keep my targets as I've never had to "prove" myself before, but I guess - you don't know me from "Adam" so I guess I don't blame you for not trusting me. I'll try to remember to take video and stills from my next day at the range so I can show you.

PS - I tried to add a few extra smileys so you'd feel more comfortable reading my post!
