Chinese rifles have arrived on our shores with brich and walnut stocks,,, limitted number, ver early imports.
Then since mid 90's to 2007 import year they came with what is commonly known as "Chu-wood", soft and often moldy but by far the most commonly found chinese stock in north america.
Starting with 2009 import year they began arriving in the current zytel/plastic in various colours but msotly black.
Hope that helps ya.
