I have an RDB and love it. Haven't put a lot of rounds thru it but enough to know it works well. It has a very good trigger and it's easier to manipulate than some other bullpup rifles. I had one of the early Tavor rifles and sold it after I shot it the first time. Just didn't feel good or handle well enough to like it.

I do like like the RDB...and the RFB, though the front ejection still seems weird to me.
