      Nathan, Could I get you to e-mail step files of your ar-15 upper and lower? They look awesome. Great work.

  • Robert Fickett

    Nathan, would you be able to do a magwell change into a chevron shape? With the front part of the chevron closest to the front take down being slightly longer. I have uploaded an image of the chevron shape I am talking about.

    Also a change in the brass deflector, to a hollow brass deflector? I can provide a file from GRABCAD of an upper that has the hollow brass deflector.

    Love your work, it looks great.

  • Casey B.

    As one solidworks user to another I can appreciate how advanced your drawing methods are. Fully constrained sketches and thorough labeling of features.
    I can work off the blueprint; But, would it be possible to have the native file? I plan on doing some modifications and it would save some time from drawing in the basic features which you’ve already done.
    I plan on adding some finger grooves in the front of the mag well.
    Thanks!

  • Mark Mathis

  • Dylan Close

    Hey Nathan I’m also looking to get files from you if possible. Although yours is awesome, I plan on changing the design and making it my own. Just trying to cut the corners of rebuilding all the technical milspec of the model and adjust the structure for custom accessories.

I have printed out the PDF and am looking for the step or iges files and I have noticed that Nathan has been offline for 2 months, so I was wondering if you are able to share the files he sent you or if you would be willing to share yours? Thanks!!! I am not trying to step on toes.

  • WVMountanieer

    Nathan, I’m new to this site. Can you please send me the step/igs files for the upper and lower for both the AR-15 and the .308 (AR-10)? Since your plan is mil spec, it would be a huge help. My plan is to customize the outer design, but still maintain mil spec tolerances. I have access to an EOSINT M 280 3D metal printer, and I really want to give this project a shot.
