[Hectic]

Seemes it works similar to a gbbr, only difference is instead of the gas being routed through the bolt the bolt houses the piston and cylinder. I'd venture a guess that drawing the bolt back locks the piston. Pulling the trigger releases it and then redraws the spring so it'll be super quiet until it's too late. As opposed to hearing gearbox wind up then pop and bb flying it'll be a pop then the cycle. Much like a pre cocking with some mosfet.
Seemes as tho the company has been around running training or some such altho it is possible that Dynamic Action Sports and Dynamic Action Systems are different companies, however the fact they use airsoft to train may have lead them to branch out into this. Either way looks prety nifty. Don't think it'll replace gbbr ' s but it would be a great option for winter play while still "feeling" correct.
