Tokyo Marui MK46 Mod 0 AEG. The ‘Rolls Royce’ of LMGs. Has a heavy recoil weight, auto stop, and the bullet belt jiggles when you fire. Most fun gun I’ve shot. Few upgrades and extras: 

Eagle6 M90 spring + 2 spacers
Nineball aep hop rubber
3 x electric winding box magazines (1000 rounds)
1 x 7.4v 2600mah Titan battery
Mk46 stock & original stock + DCA buffer tube
Reinforced dovetail mount
Original parts included
Egg box foam hard case
Viper tactical VX multicam 2 point sling

£1000 ONO

I ran 0.28g BBs which gets some nice range. Can send a video of it firing if you wish.

Can post for £15 or collect from Barnes, London.
