Ultimate Bic Airsoft Gun!




Forget all you have seen before! This is THE Bic airsoft gun. Not only does it have Semi-auto firing rate, but it also has a trigger mechanism that also stops ammo from falling out of your barrel when you tip it! Thats right, theres no worry about your ammo falling out, and you dont have to hold anything back untill you fire it. Just pull back, let go, and pull down.

***First Instructable***

*note* I started this like a year and a half ago and I forgot about it for so long. I had every stage cept the spaghetti gun and conclusion done, and im so glad i fianally decided to finish it! w00t!

UPDATE- I'm in the middle of another project right now. Its a big secret, but i havent seen anything quite like it anywhere. It's still in the design phase.

As of 3/ 13/ 09, it is in the prototype phase.

Step 1: Materials-

You will need:


*3 bic (round stic) pens
*two bic standard mechanical pencils(pencil #2 0.7 mm)
*3 medium thickness rubber bands
*one high thickness rubber band
*Duct tape
*airsoft pellets
*un-cooked spahgetti strands

*X-acto knife
*two hands. I only used one because i had to hold the camera, but you should use two.

Step 2: Step 1- Dismantle the Pen

This step will show you how to dismantle the pens properly.

Step 3: Making the Barrel

This step will explain how to cut all of the nessicary holes on the barrel. Use the X-acto knife to carve out the holes. Dont push too hard, the knife cuts through it like butter! Also make sure that there are no scraps sticking out into the pen, for it will stop or deflect the pellet. This is where you can use the drill to cut the holes. I didnt use the drill so I dont know how well it works.

Step 4: Making the Holder Things

This step will show you how to make the holders for the trigger and ammo clip.

1. Cut the tab thing off of the cap.
2. Cut the top end off of the cap.
3. Put 4 slices on the end of the cap on the oppisite side of where the tab thing was. (devide into quarters)
4. Duct tape on as shown in the picture.
5. Repeat with the other cap on the other hole.

Make sure that you test it and make sure the pellet drops through cleanly. Heres the link to Dorkfish92's "Duct Tape Keychain":


Step 5: Dismantle the Mechanical Pencil

Theres no easy way to explain this, so just use the pics. This is the step where scissors are an option. use them wherever you think it would be easier than using the knife.

Step 6: The Hammer / Launcher.

This step requires the two dis assembled pencils. Once again, use the pics.

Step 7: Make the Trigger

This step will show you how to make the trigger. This also is a bit hard to describe, so use the pics.

Step 8: Make the Ammo Clip

Ok, stuff the pen casing with the back end cap with airsoft pellets, and put it in the ammo clip holder.

Step 9: Finished! (or Are You...)

Done! But why not over achieve and turn it into a spaghetti shotgun! All you need is one of those mechanical pencil shells, the spaghetti strands (dry), and some duct tape!

Step 10: Spahgetti Gun Mod

This is a quick and easy mod for the gun that launches shards of dry spaghetti at your foes! I didnt have any spaghtetti at the time, so I cant show you the gun with the spaghetti in it. You operate it in the same way. You just dont need to listen for a bb dropping down.

Step 11: Now, Your'e Done!

Well, there you have it. Pretty much all the flaws in previous models have been solved. Any questions, comments, compliments (XD Cocky), or reccomendations/suggestions, post below.

P.S.- If your'e wondering, yes i actually do have real airsoft guns, I just like to improvise and mess around sometimes XD

    So cool. first airsoft gun. What about next weapon?


    7 years ago on Introduction

    nice! first "airsoft" gun i ever made, it hurt at 50cm and annoyed people at 5m. Good enough tho, i'm planning to make an aluminium one because BIC pens are kinda expensive here while i have ~2m of aluminium tubing lying around
    i'll probably power it with a small piece of inner tube

    very good intrutable but how do u use the reloader thingwermabobober

    I'm in the process of making something of a similar but oh-so-different nature. I'm reinforcing it with steel wire to make it more durable. Add electrical tape for aesthetics and to hold the parts better. Plus, mine will be spring-loaded.

    -UPDATE- I now have all of the things in the previous comment, five spaghetti clips(not pictured), 22 more ink cylinders(only 6 or so pictured), 22 medium-large clips that hold 18 BBs, and (my favorite) a X-Bow type launcher that my friend Zach made and I modified.


    8 years ago on Introduction

    This is my finished weapon and ammo. I have my modified weapon, a rubber band based compression clip, six large ammo clips that hold 19 BBs apiece, a small clip that holds 12 BBs, 5 ink cylinders of assorted kinds, And two different kinds of spear-type darts.

    I cut down both parts of the trigger mechanism to make it shorter so I could reach it better. I also put a metal washer on it so I could push it down easier. If you make a pressured clip, you can turn it into an instant shotgun. It fills the whole chamber with BBs instead of just loading one. I made my trigger mechanism permanent, and put a brace between it and the front of the barrel, because it was bending from strain.

    Any ideas on how to get the ends off? i used a saw to cut off the part of the pen but i dont want my barrel to be too small. those handsaws not the huge ones.

    You can see how much ammo you have left if you use a clear pen for the ammo clip.

    using the drill can destroy the plastic... i tried 2 diffrent plastic, it destroyed 2. just use it to make a dint, then scoop out, and use a knife or pocket knife to finish the job

    Actually, i didnt use my drill at all to make either of my pen guns. I was just throwing out a suggestion. But you do have the proof that it has potential to ruin your project. I guess ill stick with you and just say to use it as a last resort if you dont have a reasonably sharp knife avalible. Thanks for the reccomendation. -Matt

    awesome man! you need to come up with a high powered homemade airsoft gun now!

    I remember I made something like this. It was extremely puny! It all has to do with the rubber band... and I lost it... I did something to the pens. The pens were too small for BB's to fit in, so I heat it up and expanded the pens. It's time to make... A BB GATLING GUN!!! (I bet you a subscription that you're prototyping one).
