Ok, so I read all 218 pages of this topic. It was super informative.
I ordered my KJW M4 about a hundred pages ago and received it today. WOW! I have been slinging BBs on and off for over 10 years, and have owned every decent AEG Brand there is. Nothing compares to this sucka!. I ordered from EHobbyasia and received it in 5 days. The stuff I ordered from California, still waiting. LOL. Anyway, it appears that it came with the V1 bolt, and I was somewhat surprised, but not disappointed. Now I can get all the Cradle Airsoft goodies.
Loading the mag is not so much fun, but emptying it sure is.
