- Assembly much harder than needed
I added this to My JG SR-16 like shorty said it looks cool with a flip-up rear sight. However, it was a pain to install and it still isn't as sturdy as the old sight.
Instead of screwing into the forward foregrip plate like the stock sight, it has this bar thing that sticks back from the sight through the foregrip and attaches to the receiver (I guess?). It's hard to explain but it is too big for the M4 size foregrip and looks too small for an M16. I don't understand and no instructions were included.
So basically, my gun looks way cooler but the foregrip is looser and I can no longer use my vertical foregrip (it's too wobbly). Other than that it is great but still...terrible engineering on Echo 1's part.
