From what I have seen, it's an exact copy of the Trigger Happy including the ammo box. Fucking A! Now I can buy spare parts for my Trigger Happy M240 if I need to.
A friend of mine went to the Shot show and got to handle it. He said visually the quality of the Echo M240 is not quite as nice as the TH M240 but still pretty good. It also seems to be a few pounds heavier too. But with a price tag of $750, who cares.
The biggest question though is will Echo-1 provided spare parts and accessories for it? Mainly, will they sell spare ammo boxes. This is the guns biggest weak point. The frame that connect that ammo box to the gun is not very sturdy and can bend or break if you whack it into a rock, snag it into a big branch or take a fall. Trigger Happy didn't provided squat as far as customer support goes. And for that, I give them the one finger salute! My guess is that Echo-1 will. If so, they'll have my support.
