[ARCHIVED THREAD] - Fostech ECHO Gen 2 : A very minor machining change that yields a major functional improvement-video

Posted: 10/6/2017 8:03:44 AM EDT

Such a small change makes this system so much more versatile. I know this is bad timing to release this video but it was already in the works.

I wonder how durable and reliable these trigger systems are when subjected to long term use?

The video has an error on it wont load either was we haven't been included in the recent issues so i suggest we all stay quiet and hippie for the best and can this machining be fixed on the first one?

Fostech sells the updated Gen 2 trigger block, I think it is $25.

Thanks Mike. I wonder if that failure was due to an early hammer release or bolt bounce.

Yeah maybe bolt bounce? I had 1 ftf with my setup 16 carbine gas 3 ounce weight then i poor in a damage industries enhanced spring and havent had another problem im add-on going tp get a kak buffer set and start going up in weight till it doesn't lock back and then down again is that the proper method?

It was a light strike

Hammer follow and bolt bounce both look similar to light strikes. Generally, the indentation on the primer will be the same between a fired round and a light strike. It will be lighter with bolt bounce or hammer follow.

Sorry, I lost track of this thread for a while. Bolt bounce makes more sense with the trigger block present.

Mike, will the Gen 2 hammer block function with both Gen 1 modified and unmodified m16 bolt carriers?

The Gen2 trigger block will not work with a modified bolt carrier, it needs an unmodified standard full auto bolt carrier profile .
