that's an MT6530.
seems to be an early model since it has a steel sear block.
a friend of mine has one made in 1999 but came with a fixed A2 stock
yep. thats what it is,
the guy you bought it form just swapped the stock
he lied to you about it being a M16 upper and it having a HBAR
that is a ban era gun some body put a carbine stock on it
the C MB i s just colt, then the name of the forge company that made the blank forged upper before colt machined it.
all the parts that matter are colt. take a pic of the BCG.
it will have a semi auto carrier.
you need to tell the SWAT cop he is a friggin liar or just ignorant. cause that gun is little as he says
that barrel is still nice though. the lightweight is the way to go. it will cost you about 60 bucks to have it threaded and a FH installed. just do that and you will have a nice rifle. still pretty nice as is though
