This is (obviously) the model of MASC Assault Rifle from HALO.
Assault Rifle exists in Halo, Halo Combat Evolved and Halo Reach.
It has medium accuracy, good damage and extremely fast fire rate. It can store up to 60 bullets in the gun, and you can carry 300 more.

It took me few hours to make the mesh, and the whole afternoon and evening for the texture.

Important!
Please, give me credits for my work.
You have to ask me for permission if you want to edit this model or post it anywhere.


Credits:
Normally, I would say 'Special thanks to this guy, bla bla bla...', but now I do not have anyone who I could say thanks to.
I made the mesh, I textured it and I finalized the model (basic animations, some text...)
