Dude thats an Mk18 Block 2 You cant go wrong with that, Everything about that gun says Badass.
G&P is seriously one of the best gun brands out there.
Everything on the gun is rock solid. From the daniel defence rail system, To the Skull frog recivers.
That gun is well worth the price, like the last guy said, Put a good barrel in it, And dont touch the gear box, the magic go's away when you take out the screws..
I'v had to work on a few of these, because some people just dont have any idea what there doing inside a gear box...
