Here is my mk.18 sleeper build.

The shell has definitely seen better days, but that's the aged look I like on my AEG's

The internals are near enough new and have had less than 500 rounds through them since rebuilt

it runs an absolute beast, rate of fire is amazing, trigger response is beautiful and she's accurate too

The FPS maybe a little hot. this is unknown however the v2 gearbox is quick change model so you can just change it

via the butt stock fairly quickly without opening the mechbox.

It's just cost me a lot of money and time, and it's simply not getting the use it deserves.

The receiver is solid and has no play, there is a tiny bit on the underside of the RIS system as it's the take apart

type from the bottom, but this can be resolved fairly easily.

I'm open to trades on GBBR and Modified pistols

Will update pictures in morning as it now has brand new buffer tube and a troy industries quick release 

sling mount plate on it ready for sale.
