The Sidewinder Venom™ pre-configured magazine-fed shotgun system combines Adaptive Tactical's state-of-the-art 10 round Rotary magazine with the Maverick 88™ security model shotgun. Its lightning-fast reload action cycles 12 gauge rounds consistently and reliably for the ultimate in performance for defense, range or competition.
From the picture they seem to be pump action. Not sure why the one with a 5 round box magazine cost 140 extra compared to the 10 rounds rotary, seems awfully expensive for a lower cap magazine and no buttstock.
Have tried them Ray? How d'you like them?
