Hi DeJuan and welcome back. This model is legal in the State of Washington. Cheers, stay safe and enjoy!

after reading and researching with the semi auto ban in Washington state " In Washington, a semi-automatic assault rifle is defined by Initiative Measure 1639 as:
Any rifle which utilizes a portion of the energy of a firing cartridge to extract the fired
cartridge case and chamber the next round, and which requires a separate pull of the
trigger to fire each cartridge." I strongly suggest that you check with your local FFL budsgunshop.com/feeds/state_reg/washington_restrictions.pdf
