Convert GHK Colt Mk 12 to Mk18

[nikvanorton]

Can anyone tell me what bits I need to convert a GHK Mk12 into a Mk18. Obviously stock, handguard, barrel, but what other not so obvious bits do I need? Is it best to get them from Sixmm, WGC etc?
Any help appreciated. Thanks.

I'm far from knowledgeable on GHK though depending on the barrel nut you use, you may need a spacer for your outer barrel.

Regarding Sixmm, I would suggest you read the comments here so you understand the potential problems. I've been one of the more fortunate customers.

This is going to be a relatively brief review.

So far i have made 2 orders from them, both orders have taken 3 weeks from order to dispatch and have been split and sent in multiple packages, when queried on this i got a reply saying they were only sending 1 package however this was confirmed to not be the case when i received my first partial order.

There prices can be very good and there sale items are incredibly well priced, however other stuff is the same price as you will find at other asian retailers that will communicate better and dispatch mutch more promptly.

Unless they sort...
