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.

Nice job, did you get the Ideas from nerfhaven? And great fps for a springer.

i made one on nerfhaven, it is named the same too, but was made from 3/4 inch, my username is nerfer909, look for it.

any inside diagram on how it works or something very interesting ive been looking for a pistol for a while and i want to try to make this one !!



EDIT could we please get some parts lists and some internal pics i would like to know what parts you used thanks

Oooooohh...

380-390 fps didja say?

Wow.

Thats like competing airsoft gun.

I'll have to get the plans off of ya 8)

Sorry about double post

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.

here are the plans, feel free to make one yourself, very simple.

How did you get the area near the spring air tight?

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...

e1337, do you mean the plunger?

ouchprogramme, why did you post a blank post?

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

heres my piston
