Just wondering, has any CHing upgraded their KSC MP7 with RA-TECH's "Hard Kick" Kit?

What I'm interested to know is how much improvement to the recoiling you get after this hard kick kit is installed?

Thanks.

I checked on Saturday...but it's not in stock...
I asked Tokyo as well...they said they will be back in stock this Monday.....

Bought the hardkick kit yesterday and will try to get it done today....$120...not too bad

I got the RA-tech hardkick kit and SD rocket valve installed....recoil wise, it's better and more solid since the hardkick kit adds more weight to the bolt carrier....

Installation was pretty simple and straight forward...took me about 30 minutes...the hardest part is to put back those springs connecting the nozzle...When putting back the bolt carrier, I would suggest to put some screw glue on the threads....

I bought mine at tokyo model...
Rate of fire slightly decreased...but not really noticable....
