First homemade airsoft gun!

there are some other guys out here that have done basically this project, but mine has some important differences and advantages.
1. my project leaves your gun still able to fire stock nerf darts or stephans.
2. my project has greater accuracy
3. I have taken this project the extra distance, the completed project sports a 3' barrel and has a muzzle velocity of aprox 200 fps.

NOTE my project DOES require that you disassemble and modify your gun. YOUR GUN WILL STILL WORK NORMALLY IF YOU ARE USING A PISTOL OF SOME SORT. I can't promise that this project is compatible with the nerf longshot or maverick, but if you have a nightsight, this should work well.

Step 1 Modding the gun

this instructable requires that you mod your gun for greatest effectiveness. these are the steps, assuming that you have a nerf nightsight like I do.

pic1, pull all the screws out
pic2, separate the two halves
pic3, loosen the air chamber restraint screw
pic4, pull out the flow resistor, barrel assembly and assorted bits in the end of the piston.
pic5, the part you need to mod
pic5, the completed mod (break off the spike.)
pic6, optional mod of the airflow resistor for greater airflow
pic7, reassembled barrel and components
pic8, reinsertion. be sure to line up the teeth on the barrel and the barrel-piston connection.
(unphotographed) tighten up that piston restraint screw again (in pic 3) and screw the gun back together.

Great tutorial, one thing is how does the shell work. When I make one and put in a BB in it the shell launches it with the BB inside. I want it to only shoot BB's, not shooting nerf shells holding BB's. Please help.

[bkearney]

Hot glue it. Make sure you have it totally airtight. If you already did a PVC mod like me, it'll work WAY better.

[LordSnipe]

ps, nice tux

[LordSnipe]

try more duct tape wraping... will make the shell stick better

[hossweightlifter]

The far right middle screw is stuck the screwhead just keeps spinning without doing anything any suggestions?

[wacky_tertle]

best mod ever. I am getting BB's tomarow

[wacky_tertle]

never mind, i just used my pocket knife

[wacky_tertle]

I can't get the barrel off, help...

[wacky_tertle]

Can U use a pen for a barrel...
I like playing w/ friends but I am too cheap to buy a real gun, and I need to actually use a gun more, cuz I suck, and great tutorial

For Step 1, part (and pic) 5, I used a screwdriver with a Slotted bit ( a line instead of a Phillips, which is kind of a 4-point star shape) and put it across the little support pieces in that circle bit, pressed the piece against the floor and put my weight on the screwdriver to break those supports until the middle circle came free. The remaining junk on that circle isn't really an issue.

For optional step 6 (picture 6), I simple used a butane torch-lighter (the cigar-lighter kind, not an actual jet torch) to heat up the non-concave side of that piece of plastic until it was slightly blackish in the middle with small bubbles on the surface (and had to hold it with a small pair of metal clamps), then used my aforementioned screwdriver above to punch out a circle.

What did you do for those two steps, LordSnipe?

[LordSnipe]

If my memory serves... I just hacked at it with my leatherman. :-)
Nice and simple solution.... I suppose there's some nut out there who'd use a milling machine for this.

[spottydodz]

whats the range of this

[commentnlookr]

you can order a 250 fps airsoft thats veery acurate for 199$.
this is a simple thing, for about 10$. great instructable.

I modded my gun a couple yrs ago, same gun, and used the casing of a bic pen along with a sharpie highlighter casing and duct taped around them and put them in my gun, but I don't know the fps, it can leave a 2mm dent in drywall/plaster, about how powerful is that?

[commentnlookr]

you did it right.

[Apple_4_life]

 how does the dowel increase the FPS? im confused O_o

[cranberys]

yo im a little confused do you drill out the dowel to use as a barel or do you just drop in the air soft pellets strait in to the gun without the dowel

[calliskidd]

hey that worked extremelly well i shot my bro (8 yrs old) and he screamed . thanks alot 

[NiicKje]

hahahahah lol, ( i shot my bro, thanks alot) ? lol

[llamma1010]

i suggest foam backer rod so you arnt wasing expensive nerf stock darts

[Olah92]

Can someone please tell me exactly what kind of airsoft gun that is? Thanks :D

[nutsandbolts_64]

 which one? the colored one (it's a nerf gun) or the last pic. if it's the last pic, i don't know. for other people to be informed tell me which one

[skater7832]

good! i made one and it worked really well! It went at least 290fps. i checked on my chronometer and it was at 293 fps. Good instructable.

[Colonel88]

Not exactly homemade. Homemade is when you use PVC pipes to put together something. This is a mod, not a completely new gun. here you just put on a rubberband and a tube and taking out a piece.

[cdousley]

thats what i said

[Psycho Geek]

i like it! its crazy like me = )

[tmuterspaugh]

When i did this my finished product shot about 300fps because i used strong rubber bands and i stretched the spring out alot.

[piedoom0]

!!  More than my $40 S&W pistol!!!
(but mine looks better... hehe!)

[LordSnipe]

NICE!

[Fizzxwizz]

I agree! I'm pretty sure I've never seen an airsoft spring/air pistol shoot that fast!

[Skinr]

I have a shotgun airsoft gun that shoots 3 pellets at once, at 360 fps each.  But that was one I bought for around $60 USD, not one I made.

[piedoom0]

what I did is take an air nerf pistol (like the air shot 4000, or somthing) and put a straw on it.  Thats it.  And It fired pretty darn accurate!

[a_child_eating(zac)]

yeah it works great if u mod the spring.

[a_child_eating(zac)]

how many fps does it shoot?

[a_child_eating(zac)]

that wolld be good.  should i mod the spring too?

[mangel004]

THANKS MAN it worked great!!!!!!! at first i put too much tape but then i took some off and shot it against the wall. It hit the wall and came back at me      (i was about 10 yards away!!!).

[inZaneinthemembrane]

what kind of nerf gun was that

[firefighter1333]

the nite finder... the cheapest one...

[firefighter1333]

if u put a spring feeded mag ON TOP (in an angle so the bbs wont fall out too) then u even hav a hop-up-system! (i did that ... :D)

[mettaurlover]

your sanity must slowly be going. that's good in a nerf modder. you get all the fun mods, such as how to make a vulcan fire 500 RPM.
