i've got one in 7.62x39. it is a very nice shooter. i really like citadels 7.62x39 and 5.45x39 barrels.
the best buy around in a stripped 16" 1 in 7 twist, 5.56 nato is Brownelles has the daniel defense m4 with chrome lining for $157. it has the correct steel 4150cv and all the mall-ninja buzz words. it does have a rather small gas port and you will have to do some fitting if your going to use the GI fsb with pins. i may get one for my dissipator build one day--
