I've lost count as to how many people Denny has shot >_>;
Most AEGs lack a blowback/recoil function so, with negligible recoil, firing won't change your trajectory. A well tuned and upgraded AEG shooting <401 fps w/ .2s can reach out and touch someone at over 200'-250'. If you spend considerably more to upgrade a springer, it can go consistently to 250' with a max range of approx 300'. For the cost of that 300' capable rifle, you can make the 200' capable AEG and get spare mags/gear/batteries/smart charger.
P.S. welcome to the forums! Any questions, we'd be happy to help.
