THE RPP
this one is a little more complicaed, but worth it, it took me about 20 mins to make, and it shoots at around 380-390 fps. it is soooo easy to prime, and is quite good for its size, the barrel is about 7 inches, and the chamber is 1 inch pvc, clothespin trigger, pvc grip, 6 inch, 3/4 inch wide spring. to prime, pull the barrel forward, then pull the trigger, and it shoots. the barrel is the plunger on this gun, if you have any questions, just ask.

| 400 fps out of a 7 inch barrel? I must try this. Interesting that you move the entire barrel, I imagined -at reading the title- a plunger moving backwards around a stationary barrel, the seals against the barrel exterior and against the inside walls of the chamber. Good job, blind.

Plunger w/ electrical tape.
Maybe you could modify it so that it could be a combo of o-rings and lubricant?
How strong is the "nitefinder" spring?
I have a couple springs i stole from some water systems, but i'm not sure if it'll do...

| I still think springers are a waste of time but I have to say, nicely done and kudos for making it work.
