hello -

just curious if anyone can help me determine if the AR that i have is a preban model or post ban ? i.e. made prior to '94 ?

it is a colt sporter match HBAR - .223 cal stamped on receiver. C MP 5.56 NATO 1/7 HBAR stamped on barrel ?

is there a way to determine the build date based on the serial number ? because i don't know if there is another way to tell ?

thanks
