At $500 you could get a used TM m14 with a cheapie scope and 5 mags (or at least... I did), which are -awesome- long range AEGs. Mine, shooting 380, can pump .4's dead straight for about 125feet. And .3's have an effective range of around 150 feet, easily hitting man sized objects at that range.
Ár skal rísa, sá er annars vill
fé eða fjör hafa. Sjaldan liggjandi úlfur
lær um getur né sofandi maður sigur.
