There are features on guns, barrels which make it more accurate, but at the end of the day its the stuff which separates the £150 guns from the £700+ guns. Kick, efficiency, speed, wieght,height, comfort.
Take my Naughty Dogs shocker, has a 06 freak barrel, fires 20 + bps, HE bolt, stock dovetail and 4 point adjustable trigger, great reg and eye system with ergonomic grip frame, bolt out the back and easy removable detents.
Stock ION has poor eficiency, ok barrel, soft detents, platic parts including trigger, a physical MOF of around 24 BPS due to the solenoid.
Does it mean i destroy all, NO. I have been lit up by IONs b4.
If you are going to buy an ION to upgrade, remember that you can do it in stages and it isnt that pricey untill you start buying massive modifications. If you get a top end gun like and EGO or Shocker, you open the box, put on hopper and gas bottle and start shootin, My mate opened his ION box, shot one ball and both detents flew out.
