sorry not legal in WA A semiautomatic, center fire rifle that has the capacity to
accept a detachable magazine and has one or more of the following:
A. A grip that is independent or detached from the stock that
protrudes conspicuously beneath the action of the weapon. The
addition of a fin attaching the grip to the stock does not exempt the
grip if it otherwise resembles the grip found on a pistol;
C. Folding or telescoping stock;
G. Threaded barrel designed to attach a flash suppressor, sound
suppressor, muzzle break, or similar item;
A shroud that encircles either all or part of the barrel
designed to shield the bearer's hand from heat, except a solid
forearm of a stock that covers only the bottom of the barrel;

Huge no for WA. Sorry, same here in NY for me with this model.

Hi Adriel and welcome. Unfortunately, no due to telescoping stock, threaded barrel etc. Details under iv here: budsgunshop.com/feeds/state_reg/washington_restrictions.pdf
