Nerf Crossfire Mod

This is a mod for the Nerf Crossfire! Mine Shot far but I think I could make it shoot farther, and it worked!

This is the materials list:
1 Nerf crossfire
2 Pennies; 3!
3 Screwdriver

(this is my first instructable!)

Take out ALL of the screws, there will be 2 mini screws also, put them in a separate pile, and what ever you do, DONT LOSE THEM!!!!! (take the thing that you cock it with off then do the rest!)

 Ok so take the top off VERRRYYY CARRFFUULLLYY.Now, take the compresser (the big orange thing) out.

Put the pennies BEHIND the big spring would be and put the spring back in.

When putting the cocker back on MAKE SURE THE ROD THAT STISKS OUT IS IN THE HOLE THAT IS MADE IN THE MINI SPRING THAT IS LOKATED ON THE TOP OF THE GUN!

After this mod your nerf gun (if you do correctly) will shoot up to a yard farther!
