The most popular BB gun in the world, the Daisy Red Ryder, got converted for airsoft and here is a gameplay video from MrRJC... "Phil for as long as I can remember Phil has wanted a reliable spring powered lever gun and while he has gone through many iterations he has finally found one!

This build was inspired by u/Firebat2451 on Reddit, who proved it was possible.

In terms of this build Phil replaced the embuttment with a 3D printed one designed for 6mm bbs, with a built in TDC, fitted to a custom barrel with R hop. Sleeved the nozzle up to 6mm using teflon tube. Replaced the front sight/cap assembly to fit the new barrel. Installed a weaker spring to bring it under 1.2J."
