Really beautiful mapping. Pity that most of the receiver parts (selector, trigger, dust cover etc. - and the safety is engaged, which is sorta awkward) stay fixed.

very sweet model

Looks good, and is well made. A big plus is that the *.blend file is included as well. One thing to note and whether this is a negative or positive depends on your use-case. The bolt is not properly Textured and the chamber is only modelled as a cube with no real connection to the mag-well. In a VR setting, where gun handling might be a bit more realistic, the player would not be able to inspect the chamber ( check whether there are rounds on the magazine, by looking into the chamber with the bolt pulled back.) If you know how to use blender or any other 3d modelling software, you should easily be able to replace the internals with a mesh that fits your needs, so it will not pose a big problem. If you want to use this weapon for an traditional FPS or TPS this is likely no problem at all, maybe even a positive, because this area is not seen at all in these types of games.
