How to model notched detail on a gun? I am modeling an MTAR familiar and I have to create certain part of the gun which is quite complex. I am not sure what would be the best way of doing it, I was thinking to do it with and Array modifier and then somehow join it, or maybe by adding a lot of loop cuts.



So I would like to know how one would Approach this task?
To do this I would first add some loop cuts along your object where you want the extrusions, one loop cut for each extrusion.  Then, with the loop cuts selected, bevel them with Ctrl+B.  You can then select the proper up-facing faces and extrude them to your liking.
