Nearly all polystone...yep! .... very heavy. I got one. :loveOK for display on a rack or wall...definitely not cosplay. :unsure
Hmmm?.... polystone is a good detail casting material, but for a gun?
It is strong but brittle upon impact loads, almost like ceramic so you just gotta not drop it for sure.:confused
Not into Mass Effect gaming, but I like the "artwork" design and some of the costume, spaceship and weapon designs in Mass Effect. Got my sights on other rifles in Mass Effect as well. :cool
