FN owned USRAC (United States Repeating Arms Company, the company that owned the patents on the Winchester firearms) for a number of years before Winchster closed up shop. FN also owned Browning (Hence the BOSS system available on both Winchester and Browning firearms).
The FN Police line of shotguns ARE Winchester 1300's. They are again making Model 70's also.
In life, strive to take the high road....It offers a better field of fire.
