Did Colt ever make 7.62x39 models with A3 flattop uppers? I cannot seem to find mention of it anywhere but was advised with almost certainty on another site that Colt did make complete flattop uppers and gave the R6850 and R6851 numbers. I cannot find reference to those model numbers and thought that the "R" would be for a complete weapon not just an upper.

Thanks

The only factory complete 7.62x39 ARs that I am aware Colt ever manufactured are the R6830 and it's post-ban version, the MT6830. Both had A2 uppers and 16" barrels.

As you were advised, Colt also offered complete upper receiver assemblies that were given "R" prefixes. The R6850 is a 7.62x39 upper receiver assembly with a flat top receiver and a 16" barrel while the R6851 is the same but with a 20" barrel.

In the picture below, the rifle at the top is a factory original R6830, while the rifle on the bottom is a 7.62x39 marked lower with an M4 stock and a R6850 upper receiver assembly.

I just acquired a R6850 upper assembly with 8 20 round mags of unknown origin (that look pretty crude) some still in the sealed wrapper. It does not show much wear. I am curious of the markings that were on the original complete Colt 762 guns...were the lowers marked 7.62?

I am curious what these are worth on the open market if anyone can advise. thanks for the knowledge!

Yes:



The R86850 and R6851 upper receiver conversion kits also have a large "COLT 7.62 x 39" rollmark on the left side of the upper receiver.

I have one. My father got it when I was a baby, anticipating that I'd be too skinny to shoot large rifles when I started hunting. He was right, and I love using this thing deer and javelina hunting! After 10K rounds, it's pretty much shot out though.
