aztec - master of weapon modeling

Well, I could call ya like that if it was a perfect match with the reference picture which is for 75% the case

The missing percentages are:
12.5% = missing detail, adding more polies since the standard amount for low poly modeling has increase quite abit.
12.5% = enhance better texture quality by using a better texture resolution as ulf mentioned or making the texture by yourself.
But it still is a great model and ready-to-use in commercial projects if animated
