2002 silver cut and carved IR3
Egg 2 with Z board
Dye mizers, dye stainless breech rod
Nothing at all. Unless you want some cool eye covers or other bling for the marker. Of course a barrell and good hopper.
Reliable and quick marker. Lots of features
No lcd display. Personally don't like the small trigger.
Good gun all around. Shoots like a Timmy. Quick, sometimes uncontrolable. Bounces really well. Very accurate. Good reg, recharges well. Cycling pressure around 85 (never chops with ACE) Clamping feed neck. Easy electronic functions, battery lasts forever. Requires some TLC. (Reg needs to be lubed with dow to insure recharge consistency, and you have to buy a new seal everytime you take out the ram and internal components out) Looks exactly like a GZ but with more milling. Some better features. Better to go with a higher Timmy if you are looking for a totally new feel though. Preferibally a Lasoya or a Empire Intimidator. Enjoyable to get the feeling of a Timmy five years ago and be able to shoot one in a very similar manner with quite a few new features.
Get it if you really want to, but you get more personification with a higher Timmy. LCD display and better milling/features on the Lasoya, Empire, and Species.
