It looks like a neat idea, but it's not exactly revolutionary. They dumped the buffer spring and buffer tube system and "invented" a way to incorporate an op rod driven, delayed blowback, gas fed system.
I am sure the thing will run like a champ - and it damn well should if you expect me to pony up $2300MSRP, which is going to be closer to $3000 or so after the start of the year and the new administration takes office.
It looks'/sounds interesting, but not at that price. I can build two that will shoot just as well for the amount they want for their one 16" chrome lined unit...
