"Great conversion for the closed bolt MK16's. It's pretty straight forward if you've worked on your own gun before. If not, there's videos on youtube, so it's not impossible to do. Hardest part i found was removing my old bolt from the carrier, because it was pretty much seized. Some parts are still needed from the old trigger box for the new one.

I recommend replacing the plastic nozzle for the RA-Tech aluminum one, because they're prone to breaking. Also, because the trigger box is the same as the closed bolt version, it is still made of crap. I plan to use it until it runs into problems, then start replacing the trigger set with steel parts for longevity.

Threads on this are 14mm CCW.

"Great kit easy to install. Only hard part for me was installing the trigger safety. Its a little annoying. A must have for anyone with old version scars.

PROS-Easy to install.
Shooting 360 Consistent with .28g

CONS-Nothing except little trouble with trigger safe

"I just got this in the mail yesterday and it is the best ever, I have the m16 short mag with it and I used .25s (.2s are just too light for a longer range). But I digress I opened the box to find all of the parts neatly rapt in bags. The assembly is easy except there are a few key parts you need to save from your closed bolt trigger assembly, the first is that small rectangular aluminum part that holds a bar on the top of the trigger assembly in place, second is your fire selector assembly (be careful of the small ball bearings they like to run away). The fire selector switch will take some time to get in but be patent and you will succeed (although it may take you a few tries, and if you have any problems call or email evike they have GREAT customer service and a great response time). Other than that all the other parts fit into the gun great (the barrel assembly is a tight squeeze but because of the recoil that's good). Over all this kit is great and the gun fires flawlessly, it got me back into the milsim style of airsoft:D:D
