Not as advertised - Fostech Echo Sport AR-15 Binary Trigger

I purchased the Fostech Echo sport and wish I never had. First I found out that the guys at CE Tactical ripped me off! I was charged $424.99. When I got home I watched the Fostech video and discovered that the MSRP was around $200.00. Second "BOING" I think that some thing got launched cause parts are flopping around on the trigger group. I have tried to install the trigger and "No Joy". The videos that I have watched all leave a small detail here and their, possibly because the vloggers didn't want anyone to know they couldn't do it either. The third thing is that in order to run this trigger you have to mod your full auto BCG and run a heaver buffer spring and weight. Then there's the customer service or lack there of. The individuals at Fostech can't help you as they don't know about most of the problems due to lack of pre release testing. And don't even try the manual, unless you're trying to start a fire. In short this is a total rip off with no redeeming values.
