Getting it to shoot far is one thing. Shooting straight is another.
Getting more distance out of a sniper rifle is a mix between the FPS, Quality of the hopup and the hopups adjustment. The Well l96 stock doesn't really cut it much stock so an AEG will probably easily out do it simply with accuracy through volume. Doesn't take much to lift your AEG up to lob those BB's an extra dozen feet or so.
You're not so much of an Airsoft pro are ya? :P. I kid.
Don't expect much from chinese clone shit.
