One of the most iconic guns in movie history, the M41A Pulse rifle featured prominently in the Alien movie franchise and has been faithfully recreated in airsoft form by Snow Wolf. Based on the airsoft Thompson platform, it is a fully functional airsoft AEG, firing 6mm BBs at approximately 250fps. Selectable safe, semi and fully automatic fire modes At the front end of the gun you will find a working pump handle that is just for show; rock is backwards and it exposes a dummy shotgun shell in the breach. Extendable aluminium stock with multiple positions. Remove the lower magazine compartment lid and you can eject the Thompson style magazine. Holds approximately 300 BBs and winding is required. There is a working display on the right side of the rifle that mimics the rounds fired counter on the movie gun. Plug in a 9V battery to turn on the display. Integrated carry handle Working charging handle and adjustable hop-up unit. Main battery compartment is located in the front end of the gun, just swivel the front cap 90 degrees to access the battery harness. An 8.4V NIMH stick battery is recommended. You can modify the battery compartment to accept 7.4V Li-Pos, but you need to remove some of the internal plastic moldings. Battery not included, located here. Charger here. Length: 680mm-790mm Weighs: 3.75kg Fires at: 255fps Note: The stated muzzle output has been measured by ourselves with a 0.2g BB and will be frequently remeasured. Variations of +/- 10% are possible, but always conforming to the Irish 1 joule limit.
