This is a classic style buffer tube to finish your next AR-15 build.High strength aluminum ,at mil-spec tolerances and dimensions.When you thread this pepper into the end of your lower receiver,you will know you made the right choice.
This is one of the coolest 3d build kits ever designed , and put together! This build kit comes with all the parts needed to manufacture or print your own AR-15 chambered in 5.56 ! Cheap ,controllable ,and most importantly AVAILABLE. The 5.56 is a great round to have in an AR-15 platform. The lower receiver and buffer tube system is identical to that of any 5.56 or .223 AR-15platform, this means you can swap any AR15 platform upper receiver onto this build, the best of both worlds in one!!! The lower receiver contained on this sd card uses NO HARDWARE…..I REPEAT,NO HARDWARE!!!! The SD card contains two files a raw STL file for modification ,AND A PRIINT READY GCODE THAT IS READY TO GO!!! just preheat ,auto hone, and print!
