Nerf Gun Modification 101

Step 2Upgrading: Part 1

Upgrading: Part 1
Now it's time to make this thing work well. There are 3 ways that really help performance.

The first is to upgrade that big fat spring. It's found in the big orange cylinder. Right now it's about 2 inches in diameter and around 6 inches long. You have 3 choices. You can add a second spring, you can stretch it, or you can use a spring from an AR-15 assault rifle.

If you decide to stretch the spring, make sure you know what you're doing. Spring manufacturers know what they're doing. When you grab it and stretch it, it will work well for a few times before it gets worse than how it used to be. My bet would be that if you have to do this, you can stretch it, hit it with a blowtorch, and let it air-cool.

A second spring doesn't seem to help, unless it fits perfectly. The best thing to do is get one from the AR-15. They're about $15, and the same size except 11 inches long. You'll want to cut it down, but man will that thing help.

If you're going to end up buying gun parts for your nerf guns, why not just build your own nerf gun from scratch?

when adding an extra spring, put a foam stick on pad on the end of the plunger that has the O-ring, it softens the blow so your gun doesnt crack
And you can remove the orange bit behind the cylinder, its non-essential.

WAIT A MINUTE, an ACTUAL AR-15 Assault Rifle?!?! Sorry, but, WHERE THE HELL WILL I GET THAT?!?! You can't buy Ar-15's,......where am I supposed to get the spring from one?

Ok, cool, thanks. But, I don't think the government would like me too much if I was ordering a part for an Assault Rifle.

I know the Ar-15, you don't have to give me a history. But, Canada's gun laws REALLY suck. When I'm an adult I'm moving to the States just so I can own guns.

Young Instructables Troll, you apparently don't know what you're talking about - again. Why do you keep thinking everyone lives in Canada?

What?? I live in Canada, I was simply stating that, if I did live in America, buying an AR-15 assault rifle, WHOLE, would be a hell of a lot easier. Also, I'M NOT A TROLL, obviously.

You can use the spring found inside the plastic toilet paper holders at the dollar store. It works really well.

Anyone have any suggestions on were to get a AR 15 spring?

i used a rather strong spring inside of the original spring and now it won't stay cocked, do you have any suggestions on how to beef up the cocking mechanism?

put a recon cs-6 spring inside the longshot spring.

food for thought: I've heard that if you use to strong of a spring it will eventually break the cocking mechanism.

Do you have a suggestion for someone who can't get an AR-15 spring?
Apr 8, 2009. 6:12 PMasterisk890 says:
ok, thanks
Apr 8, 2009. 3:43 PMasterisk890 says:
I mean, other than a second spring or stretching it, since you seem to be implying that both of those methods don't work well.

Are you talking about an AR-15 stock buffer spring?
