Precision Armament m4-72 Brake 30 Cal

Looking to sell the brake that came on a rifle I bought. Brake is a m4-72 30Cal brake from precision armament. Great quality brake and works really well, but it’s a 30 cal and the rifle is a 6.5mm so it’s just not as effective as I’d like. 

Unknown round count but In great shape. Comes with the crush washer (always recommended to get a new one) 

Asking 100$ OBO. Shipping on buyer.
