Fostech Echo 2

These interest me a little bit. Anyone here have any personal experience with these.

Not with the Fostech. I’ve got the Franklin Armory BFSIII.

What do you think about the one you have? I'm thinking of putting a binary in the 11.5" AR Ive got coming?

Like any other tool or enhancement, they require training and practice to use effectively. They make controlled pairs super simple. If you just want a fun toy to mimic FA fire, they can be fun for that as well.

Controlled pairs is what I would be looking for. God knows ammo goes fast enough without trying to mimic full auto for fun.

I've got the Fostech and iirc Esko has one too. Works fine, though I opted for the lighter backup disconnector spring that drops it to the 3.5lb to 4lb range. It was faster shooting with that setup. Run it in a 16" mid length and 12" carbine upper and worked fine with both gas lengths. H2 buffer

any updates?  read some funky stuff about the foss after about 500 rds...  a spring design?  

love to hear reviews w/ a lotta rounds fired.

I ended up not getting one. I just put in a Geissele SSA-E like I have in my other 2 AR's. I get pretty fast split times with those and I know they work and ammo is just too high. .

I seen one in a PSA 10.5 and it had trouble with it out running the bolt, I believe. It light strikes the 2nd or 3rd round. I was told a H2 or H3 buffer would fix this however my research there. From my understanding you need a longer gas system for it to operate correctly.
