Early AR-10 style pistol grip for your BRN-10 Retro.
3D Printed pistol grip for the Brownells BRN-10 Retro that mirrors the design of the of the Armalite AR-10. This is a different design from the Brownells offering which appears to be a mix of the Portuguese shape with the early Sudanese back strap features.
Run it as is or sand and paint to your liking. Wet sanding is needed as dry sanding can melt the plastic. I suggest Rustoleum 2X in Kona Brown for a proper retro look.
