I have owned a few colts over the years. That in mind I made no hesitation in snagging a $1295 6920 LEO carbine new from SAW sales and a 6721 reciever as I wanted a rifle marked AR15A3 but don't like the 6721 upper.
Anyhow, in the mean while I picked up a used 6920 circa 1995.
The 1995 colt is what you would expect. Nice fit, nice finish. The AR15A3 6721 reciever is also top notch and flawless with one of the nicest anodizing jobs I have seen. Of note, both of these are marked Colts Manufacturing.
The new 6920 is marked colt defence and I am here to tell you it does not measure up to the other two colt products mentioned above. There is at least 4 colors. The lower and upper do not match, the carry handle matches neither and the small parts do not match. The rear sight block is loose and can be rotated loosely almost 1/4 ". The handguards look crappola side by side to the older colt, but are tight and functional I suppose. The upper receiver and bolt carrier look like they were cast in a sand mold. The T numbers were painted and the excess whiped off with a snotty kleenex leaving white residue in the picatinny grooves and down the side of the upper receiver. The pistol grip looks like an Afgan made it in his mud hut. The roll mark of the reciever markings and the pony are deep on one end shallow to non-existent on the other. The FSB is also a product of poor casting and very poor flash clean up.
If I were you guys, I wouldn't waste your money. All in all, I kinda expected this. I suppose Colt defence has cut some corners in the beauty department to meet the demands of a military at war.
Having said all of that, I am satisfied with the rifle and very satisfied with the AR15A3
receiver.
