This DIY airsoft design is one of my all time favorite projects. It's super inexpensive and can be put together in just a few minutes since it's only made from two parts! A pen tube could be substituted as the barrel to make the project even less expensive, though a little less accurate. As with all airsoft guns, eye protection is required for safety!
The parts used in the video were a 24oz soda bottle and a 5/16” x 8” brake line (for the compact version), or a 5/16” x 28” brake line for the longer model. Brake lines are available at any auto parts store and usually cost between $4 - $7 depending on the length. So long as the diameter is 5/16" to properly fit pellets, any length can be used.
You can check out my sponsor www.ThruNite.com for the brand new Archer A2 v2 and A1 v2 flashlights seen in this video (maybe for some Christmas gifts?). They're waterproof and run on AA batteries, with too many cool features to list. A glow in the dark ring around the lens is something I've never seen before that looks really nice and helps to easily locate the lights if they've been set down in the dark. Like all of ThruNite's flashlights they're also exceedingly bright. Links to purchase these lights through Amazon will be posted lower in the description.
There are endless possibilities for how this airsoft project could be customized if desired. I went with a pretty simple design with the PVC housing seen in the video. It's function was to simply improve aesthetics as well as add a more stable grip to the barrel. I know some of you will want to have the exact parts I used for the housing so I've listed them below. You can figure out the details of how it's assembled easily enough by pausing the video. The only modification needed for any of the parts is to drill a hole for the barrel through the end cap.
