Front sight is a bright orange band, with peep site in the rear. Its the 590a1 Special purpose model. 99% identical to the bayo model from what I can see. Look for yourself on their website. (edit: NVM they changed their website...it sucks can't find it anymore.)
I guess the question is, does a rail on a shotgun (it is a shotgun afterall), and bayo merit $300? I'm going to say no.
Pretty huge upsell for a little bit of "cool" factor.
