It's a shame they don't sell the longshot over here, the only way to get it is ebay from the US at stupid shipping prices :(

I've been looking at modding my pc up a bit and this would be a far cheaper way to start to get the hang of it.
At the moment I'm thinking just buy some Games Workshop spray and then as everyone is saying stick a dry brush effect on it...

I've been wanting one of those Havoks for a long time now, but with 3 extra belts so it'll have a 100 round chain feed...

I am really impressed with the level of the mods, I especially like the steampunk ones. Though at this point I am more into modifying my real firearms over nerf ones. But they are still cook nonetheless.

If you compress a spring from fully uncompressed to being compressed by three inches, your energy is one half of the spring constant times 3^2 - 0^2 = 9 - 0 = 9
If you compress a spring from being compressed by two inches to being compressed by five inches, your energy is one half of the spring constant times 5^2 - 2^2 = 25 - 4 = 21.
That same 3" displacement now has over twice as much potential energy, because it is pre-loaded.
The change in force is the same, but the absolute force is higher, so the change in energy is higher.

Assume that the same spring is used in the gun and can compressed to a maximum of 4 inches. Assume also that as standard the slider used to compress the spring can compress it by 3 inches. 3 inches of compression would require 3lbs of force. So, you compress the spring, pull the trigger and the spring fully extends releasing the 3lbs of force that was put in.
If the same spring was preloaded by 1 inch then it has 1lb of force stored in it as potential energy. It now takes 1lb + 3lb to compress the spring. Once again, you compress the spring, pull the trigger and the spring extends the same 3 inches it did before as there is a finite space available within the gun. The spring remains preloaded by 1 inch and therefore retains the 1lb of force as potential energy so only 3lbs of force is released.
