This is 'M41-a Pulse Rifle'. It is a fictional pulse-action air-cooled assault rifle used by the U.S. Colonial Marine Corps and the U.S. Army in the Alien films. Its my biggest model so far. Dad says this models is ma best one, I think he is right, cuz its made in 1:1 scale and it looks like as if its made of plastic. But, when you hold it in your hands, you feel the paper. I need your precious comments on this one and please do write your email id after your comments and your name as well. Thanks for visiting. Call me or email me if you want to buy / order any of my completely built models (Please be noted that the plans are not sold here).
