I will be posting another video here soon. Fran (the sniper in the previous post) and I installed all those upgrade parts into my M4 rifle. If you think the rate of fire was pretty high with the 9.6V battery, wait until you hear it now! MOSFET...hmmm...me likey!
We went through the entire rifle... changed out the internals except for the three gears. Fran knows alot of tricks to increase compression (raise the fps) and reduce the overall noise. I put in a new 6.03mm "tightbore" barrel and now it's pretty close to the accuracy of my sniper rifle. Except it shoots at ~1000 rounds per minute! More on that later.
Hope you all like the video and rush out to you local battery supply shop!
