Another M4A1 from MW2, this time with a holographic sight.
What's notable here is that I have discovered a new technique for precision work. Simply grouping and enlarging runs the risk of losing things in the white void, and there can a discrepancy in placement when you shrink it back down again (white spaces between parts, parts offset, etc). Also, you still can only move it with the arrow keys increment-by-increment.
However, if you use ctrl+scroll (or your browser's equivalent of zooming in), you can make the flash object bigger and therefore what you are working on bigger. All the elements should rescale as you zoom, and it's also much easier to move things precisely (between increments) via the mouse. I used it to precisely align the suppressor, the tape on the magazine, the aperture of the rear iron sight and the holographic sight.
Note that while zoomed in, there is some lag and accessing the toolbar is a bit hard. It's still a great way to do precision work, still.
