Wondering if this has something to do with its accuracy? The barrel is smooth bore, BUT, whats going on here at the muzzle end ??? Never seen this before....In the last pix.you can look straight down to the barrel. But the BB is too small Dia. to be touching the lands & grooves at the end of the muzzle........Maybe something to do w/the airflow around the BB as it leaves the barrel .Interesting,I've never seen this before on any gun......Any ideas ? Some info here >
