Intro: How to Make a Hopper for an Airsoft Gun Out of an Old Bottle
If you always run out of bbs when using a machine gun then this is for you.
You will need
2 water bottles of the same kind
airsoft gun that needs a hopper
Step 1: Putting on the "adapter"
This is the most important part because if this isn't made right then you won't have a good hopper.
Start by taking a cap and poking a hole in it and then make the hole larger like it looks in the picture below
Then glue that cap on like in pic 2 so that it goes over the place where you would usually put the bbs in
Step 2: Making a Plug
This is in case you are having a very short match and don't need the extra bbs.
Cut just the end of the bottle where the threads for the cap are and where it is the thick plastic. You can throw the rest of the bottle away. pic 1
Then glue a piece of plastic (from the bottle you just threw away) over the hole on the opposite side of the threads. This will keep bbs from falling out Pic 2
Step 3: Some Tips
Try to find a couple different sizes of bottles that have nearly the same cap, that way you can have different sizes of hoppers. Also if the bbs aren't falling into the regular storage area for bbs then just give the gun a shake and the will probably fall in.
I chose a big bottle, that holds about 3000, because when I use a machine gun I don't like to have to worry about saving ammo, even though I probably don't need that many bbs for one match
