Hey guys a big hello to all echo 1 fans! I just wanted to see if any of you here have had the same experience. I was looking for a way to mount a leapers red/green dot scope on my echo1 MP5J and a I found several different mounts that might work. I went with a low profile mount scope listed here:

So my question is what mounts are compatible with this gun?

I am looking at several others now including:
