Please go easy on me 'cause this is my first instructable. This is similar to the modification by carrtoon on nerfhave, but it was indepent invention (I didn't use his mod).
Here is a video of it firing on and knocking down a styrofoam target. Note- there isn't any sound to this video. When it fires, it makes a loud gunshottish noise. Doesn't teh bullet go fast?
Step 1: Unscrew and salvage
Unscrew the body of the recon and remove the spring. Save the barrel extension. Don't leave the screws lying around so you won't confuse them with the Longshot's screws. for some reason, the notes arent working on the image below so I put them here- this isn't my picture and take the large spring out.
