Halo 2 Anniversary Battle Rifle Upgraded Parts

TheApropalypse's model is really awesome. I felt that some of the parts weren't up to par, however, so I decided to upgrade them. There are 3 upgraded parts in this Remix.

Edit: For some reason the original make that this was remixed from is gone. Here's the new one:

1. Barrel - more screen accurate to include grips and most importantly 3 tines. Hollowed out to use less material as well.

2. Bolt - More screen accurate to include knurling. Also insert an M3x20mm socket head cap screw to make it more robust and resistant to snapping off.

3. Magazine - This is the big one. I've made the upper part look more like an actual magazine. I've also modeled a 9.5x40mm battle rifle round to be glued inside the magazine. Additionally, there is a hole to insert an 8x3mm disc magnet to keep the magazine inside the magwell without needing a physical latch. The other magnet goes into the peg that goes between Stock2 and Stock3. Make sure the orientation of the peg and magnets are correct before gluing!

8x3mm magnets can be found at The Home Depot if you just want a few or online:

I recommend the larger pack because these magnets are nice and strong, and can also be used to make extruder indicators for stepper motors.

One more remix I'd like to make is a hollow scope that I could put acrylic lenses on, but the stl file is too high poly for me to edit in Fusion360.
