The McMaster Blaster is an easy to build, serviceable, modular upper receiver for a bufferless AR-15 Platform. All parts aside from the barrel can be found on McMaster Carr in some form. Most, if not all parts are able to be found in 3d printers and household items. This platform will be built upon, and scaled up.
This upper is for educational purposes only. Information is art.
If you have any problems, suggestions, or complaints, put them in the comments below. I am not great at this, teach me something.
