Apparently this has been out for a little while now. I just ordered one a few days ago.
Has anyone had any experience with these yet? If so what had to be replaced in the gun and how was the performance afterwards?
Also does the cradle velocity reducer still work?
Another thing is will the new bolt catch work with the V1 bolt?
I've been getting mixed reviews all over the place.

Long story short:
The V2 Bolt also comes with 2 parts needed. Those two parts (Mag Catch and Buffer) Need to be installed.
I haven't heard about the V1 bolt and new bolt catch. BUT: The new mag catch is STRONGER to accommodate the heavier Buffer. From the photos I've seen of it, it's just a reinforced part so should work.
The Cradle reducer WILL work in the V2 Bolt.
The V2 bolt no longer requires the "retaining" band and INCREASES Felt recoil. Some have shown wear on the bolt at thousands of rounds down range. The KJW still has had no catastrophic failures even with the heavier buffer.

With the V2 do the lowers still crack at the buffer retaining pin?

Thanks for the info trust.
What I had in mind was to be able to swap the different bolts during a game and go from 400+ to 350 depending on the situation.
I'll have to play around with it to see.

Just got the version 2 bolt installed. I also installed the revised buffer but I didn't bother installing the new bolt catch and it works just fine.
It looks like they addressed some of the problems of the lowers cracking. The new bolt and buffer have been modified to take a little more pressure so that it doesn't all go to that retaining pin.

Just ordered it direct from KJW.
Got it for $35 shipped. Definitely worth it.
The e-mail is sales@kjworks.com.tw
This is what I e-mailed them:
Hello Diana,
Could I get an estimate for the KJW M4 Version 2 Bolt shipped to Michigan in the USA
using paypal? Thank you very much.
