Due to the pocketing on this receiver, we do not recommend the use of an ambidextrous safety.
The Palouse is a forged set and may not be as tight as our Balios, Aethon, or Xanthos receivers.
Although we do our best to match anodizing, 2A Armament cannot guarantee exact anodizing matches between parts and we will not exchange parts due to different ano finishes.*Due to the large range of machining tolerances on the market, we cannot guarantee fit and function with third-party products.
