So I Modded My Rf20

I've been planning this mod out for close to a year now; and with a couple weeks of work, finally I finish. Enjoy.

Posted Image

Along with standard mods, I added 2 Magstrike bladders, drilled the piston's air feed hole, expanded the piston volume, and gave it new barrels. I also replaced the pump with a Magstrike pump because the rf20 check valve melted from over-pumpage. A bike pump would do a lot better.

I knew expanding the piston volume would drain the air supply too quickly to fire all 20 shots, so I sacrificed 2 Magstrikes for their bladders. You'll have to plug one of the holes that exit the bladders with something, then put new tubing on them. 8" should be long enough.

Posted Image

Take the white piece that the RF20 bladder goes onto and drill 2 holes into the back with a 7/32 drill bit.

Posted Image

Cut the end of the tubing coming from the magbladder's lengthwise 1'. This will help you feed the tubing into the holes you drilled. Use lots of super glue to hold the tubing in there.

Posted Image

Here's the internals so far. Dremel some spots for the tubing to come out of the shell.

Posted Image

Pop the piston open. There's a helpful guide on the Merry Men of Michigan's webpage on how to do this. There should be a hole under the moving seal piece on the end. Drill into it with a small drill bit. I used a CPVC spacer to hold the seal away from the drilling.

Posted Image


Follow the guide from my Assault Magstrike writeup to put a PVC expansion on the piston. You'll have to dremel some of the shell away for it to fit.

Posted Image

I was going to use a RF20 spacer plate on this, but I got impatient and figured out an alternative. Cut the back off the stock barrels. Then pull the center out. (Middle piece not pictured)

Posted Image

Use that thin center piece to space apart the inner 10 barrels of the turret, and then hot glue the outside barrels to that. Reinforce it however you want. Use half a tube of goop on the turret piece and stick the barrels onto it.

(Look at how well those barrels are done. It balances on the little washer on the back of the turret!)
Posted Image

Cut the barrels somewhere between 6-10". I left mine at 10" for the time being,but I will probably cut them down to 8". Once everything is all done, hot glue the bladders to the sides of the rf20.


Ramrod 20 darts in, pump it 120-150 times, and unleash the pain. Ranges are yet to be determined, but I believe this is the farthest shooting rf20.

With 8.5" barrels, 120 pumps, with 2 bands on the piston, flat, the darts landed between 70' and 90'. So I'm going to say that it's official range is 80' average.

So wait, does the expansion help because it requires the gun to draw in more air before the piston is all the way back? Nice mod, by the way.

But 120-150 pumps? Does that only last you 20 shots? I mean, no wonder you have so much power, but...

Jesus Christ. oodalumps, every post i've seen of yours is awesome. First the triple shot SS1, now this?! You're gonna have to estimate ranges at the least. Even though it takes a while to come up with these incredible mods, it's worth it. Seriously, keep it up. Great job.

EDIT: Zorn's Lemma, please don't say that.. Ever. That would be overkill, unless what you mean is hooking this up to an air-tank. If you mean 2 rf20s, that would be stupid. 240 pumps for 40 shots.

I love what you've done to this. I can see it now- In a war, you'll spray 20 shots in the air. The round ends 5 minutes later. The next round starts, it's 10 minutes into it, and a hail storm of darts rain down on the other team. Damn...

It might take half the round to get to 120 pumps!

Anyway, nice work. Very cleanly executed.

Now you just gotta hook up an airtank to that crazy bitch goose. But seriously, awesome job on making the RF20 a hell of a force to be reckoned with. And if you could give a range estimate, I'd definitely appreciate it.

Very nice.


I'd rather pack that 20 shot bad boy than try to run around with an underpowered 25 shot Vulcan.

It's clean and looks like it means business. Extra cool points for sacrificing two Magstrikes to get the air delivery squared away.

I have been having tons of problems with bicycle pumps. you need to look for a small diameter, metal, single stage pump that has a valve capable of being attached to a nerf gun without leaking or exploding.

I have yet to find a reasonably priced pump that is any better than a bigsalvo pump which is now my benchmark for nerf pumps.

I dearly applaud you Oodalumps. Although...

1. Could you use a homemade air-bladder instead of sacrificing to magstrikes?
2. Could you attach a homemade PVC airtank instead if you can't do #1?

Three air bladders. Getting good ranges comes with a cost. After it shoots 20 times though, there's still around 30-40 pumps left in there, so it's not so bad after the first time. But It's been taking me even longer than you would expect to pump this up. I take a break from pumping every 30 pumps so I don't melt the pump. I really need to do a pump replacement on this.

Now you just gotta hook up an airtank to that crazy bitch goose. But seriously, awesome job on making the RF20 a hell of a force to be reckoned with. And if you could give a range estimate, I'd definitely appreciate it.

I stuck with the magbladders because they were more Nerfy. I'm not a fan of homemades. But It's not like they cost much; 5$ per magstrike at Target back when they had a sale (I bought them all).



Ranges at the moment are like a turreted 2k. I'm still planning to tweak it a bit before I give official ranges.

Too bad it takes so many pumps. If it had shorter barrels then you wouldn't have to pump them that many times, but you also wouldn't get the ranges. hmm.

Thats pretty cool, i must say.

if you drop that thing on its barrels, they are going to SHATTER under the weight of the RF20.

other than that, it's pretty goddamn awesome.

What in the pump will "melt" if you pump it all at one time?
Also, I think we all want to know how far it shoots.
