M4 Bolt Catch

[fightingirish]

Hey guys, I've been looking around on the interwebs trying to learn how to rig up a working bolt catch for the KWA M4. It isn't totally necessary, I just like having that option when I'm adjusting the hop-up. As some of you know, I'm not as familiar with AEG's due to all the sniper rifles that have occupied my time, so this is kind of my first experiment in this realm.
So any suggestions? I understand how it works on the real steel, but I'm assuming it's a tad different on an AEG. I've looked at a few body upgrades with working bolt catches by King Arms as well.
Like I said, I just like the idea. If it's possible, fantastic. If not, oh well. Let me know of any ideas or suggestions.

Unless you have a TM M4 SOCOM/SOPMOD, Systema, or Celcius, you cannot have a functional bolt catch.

Now King Arms makes a metal body upgrade which has BOLT LOCK which just means if you pull the bolt back, you can lock it into place. Dboys makes their pot metal bodies which has it too. I think the Dboys cost only 50 bucks.

So if you want bolt catch, buy a TM SOCOM/SOPMOD, Systema, or a Celcius.

If you want bolt lock, you can just buy a metal body kit. To my knowledge, the metal bodies are made a little differently to have the bolt lock.

As for bolt catch, there are no mods you can do to get that.

Fair enough. Like I said, I was just curious. If I'd have to buy a new body it really isn't worth it. Thanks for clearing that up for me, man.
