Pinned down by a sniper with a £900 Silverback?

Surrounded by kids in hoodies, hip firing JG G36s?

You need to break out, punch a hole, send em packing! Send in the armour! 

This is a genuine Tokyo Marui M1A2 Abrams RC tank with firing gun - capable of firing 0.12g BBs up to 25m in distance. It holds 40 BBs, so that's 40 kills soldier!

The turret rotates through 320 degrees, and the barrel as a max elevation of 20 degrees - all controlled through the handset. With rubber tracks, and independent suspension, it can also climb inclines of 35 degrees and move over difficult terrain with relative ease. This is garden plinking on a whole different level. Rubble, soil, cats, it will climb over small obstacles quite well and the rubber tracks give decent grip. 

BBs are loaded through the hatch on top, which also houses a secondary power switch (safety) just for the main gun. The tank itself is powered by 8 AA batteries (although you could possibly switch this to a Lipo pack if you know your wiring) and the handset takes a single 9V battery. 

It's a little dusty from being on my display shelf, and is a little faded on the right hand side but otherwise is in full working order. I've owned it for at least 10 years and had many laughs stalking house mates at uni with it. Originally purchased from Model Zone, I don't have any of the packaging or instructions, but you may be able to find these online.

Unfortunately it will only take 0.12g BBs, I've never tried 0.25 in it and wouldn't advise it. If you got a jam it could be quite difficult to free up.

There's a further write up here. 

I can post, but can also arrange for collection in Cambs or Beds - postage would be via courier, and would probably be in the region of £10-15 as it's a bit heavy.
