The UK is seeing a major shortage of ammunition
As made by Tokyo Marui, this is the infamous Desert Eagle .50 Cal (seen here in plastic black finish), as seen in many an 'Arnie' film and even the weapon of choice for 'The Agents' in the Matrix Trilogy, this is a BIG pistol, suited to those with either big hands or a big personality! This has the biggest kick I've ever seen on a GBB pistol, even using standard 144a gas, this still kicks like a mule! This fires at around 280 FPS (with 144a gas), this has a 27 round capacity magazine, this locks back on empty, the usual TM quality plastic outer and the efficiency is such that you should get 2 magazines worth of BB's per gas fill. This is designed for 144a gas/Predator Ultra gas only, use anything more powerful at your own risk.
As with all Gas Blow Back weapons, performance varies depending on ambient temperature and speed of firing.
