Hello this is my first mini (i have built 2 nerf guns) and I would really like feedback on it. I am hopefully going to make another version but I want my next version to be the best it can be. I used a small pill bottle for the chamber and a barrel that fits airsoft bbs extremely loosely.I took the igniter from a lighter and use ax in it. I was wondering if just having bare wires in the chamber for ignition is not the best, should I replace it with nails or screws? also does anyone know if there is a way that I can get a clip and possibly use it for airsoft battles if i had a hop up? I will probably get a tank and compress it with air so I just have to press a blowgun handle to prime it then pull the trigger. Here are some pics:
EDIT: any suggestions please share!!!!

| I would recomend using a piece of 3/4 pvc or copper to hold the compressed air and use 5/16 metal fuel line as the barrel a blowgun will work for the valve |

| 5/16 line is a good fit for airsoft bb's. |

| ok thanks and by the way does having screws for the ignition create a bigger spark? and where can I buy the 5/16 fuel line? |

No I don't think using screws makes a difference but it just makes the spark stay in one place because the screws are stronger than a plain wire.
You can get the line, I think it's brake line... at auto stores. |

| No problem, it should only be a few bucks for a few feet, far too long for this gun but you can use it for multiple guns. |

| Cool, BBMG's are cool too and not that hard to make, just do a lot of research in the Wiki and in the showcase. |

| Metered fueling (syringe would be easiest), chamber fan if possible, longer barrel. |
