The below video of a 3D printed Ruger 10/22 Charger has been making the rounds on the internet, upsetting tech bloggers who never realized that people have been legally printing firearm receivers for other guns, such as the AR-15, for years. The designer of this 3D model has not released the model files online (yet). I am sure it won’t be long before someone replicates the model and makes it available online. The same model could be used to print polymer Ruger 10/22 rifle receivers.
