M4 Short Barrel Speed Soft Airsoft

Edit the picture shows an outdated version of the barrel, the side of the carbon close to the gun is flush with the 3d printed part in the new version. Will update with new pictures soon. This is a 14cm speed soft conversion for airsoft M4's. It is 14cm long and connects to the gun with the integrated barrel nut. I have had great results with this, it makes indoor field on absolute blast with how easy it is to move and peak corners with this guy. Great combo for a slanted stock if you wanna go full SSG style. Your inner barrel will need to be cut down to length for this project i last about 70 FPS.The piece that holds the hop-up unit is a tight fit on the hop up and essentially makes the spring irrelevant but will still work with the spring. I made mine with PLA and it takes hit like a champ 350+ FPS has only left small dents. I printed the PLA at a high temp to improve layer adhesion but would recommend a strong material. A 30mm carbon fibre tube was used around the barrel, its a snug fit!
