The M11 was built by Rem here in America whereas the Browning built at FN in Belgium until Browning had them done in Japan. No they are not an exact clone. No magazine cutoff switch on the M11 and too place a shell in the M11's mag ,you need to depress the bolt release button on the receiver. The Browning you just stuff the mag. I have both and really like them. If your thinking of buying parts for one to use on the other, better think again some might interchange with no problem but not all. MM
