In 1993 Col introduced a new caliber into its AR15 line up. The gun was marketed as a hunters carbine chambered in 7.62×39 a round more or less identical to the .30-30 WCF.
The R6830 was a 16 inch barreled carbine . The barrel is not really what we think of as “lightweight ” these days and is closer to what many would call heavy. Probably good because the x39 round has noticeable recoil compared to the 556. The barrel does not have a chromed ore on these. The upper is a A2 fixed carry handle type.
The sights are the same as the A2 except the lack the markings found on 556mm guns since they would obviously not match.
The gun was made during that weird period before the 94 AWB and after the important ban. This was a time when a lot of pressure was put on Colt by the feds and gun rights were being pushed back. The result is this model has the sear block and no bayonet lug. But it does have a flash hider. The hider is the A1 style and not the A2 style with the closed bottom.
The bolt and barrel are really the only major changes. The carrier is the same as a standard AR15 and most other parts save the barrel etc.
The front sight base is standard with all the usual markings for its era . The only difference is of course the milled off bayonet lug. This was done in a wasted effort to get the antigun kooks to back off. Since a bayonet can not work on a 16 inch barrel carbine with a carbine length gas system, the lug is pointless anyway except for making leftists twist their panties. The front sight is the A2 post.
The Carbine also came with the A2 buttstock and pistol grip. The solid stock was a good choice I believe as it helps with the recoil and comfort for a gun meant to be sold as a hunting rifle. A 762×39 carbine AR15 with the collapsible stock is not comfortable for the casual user. The hand guards are the slimmer CAR15 type.
You will see some people online talk about how the 762×39 ARs don’t work reliably. Seems when I read this or see some one in a video talking about it, they are holding some frankenparts gun built up by bubba. The colt carbine has been nothing but reliable when using the factory mags or the one Cproducts 30 round mag I tried.
The mags that came with the gun are nothing more than 30 round mags with a blocker in it that limits it to 5 rounds and a floorplate marking it as a 7.62×39 magazine. You can see the installed block in the picture below. In a pinch you can load about 5 or 6 rounds of x39 into any AR15 magazine and it will work. Though more will cause problems due to the geometry of the commie case and the magazines not playing well together.
So how does it shoot? It shoots pretty good. It is an AR15 after all just one in a round not exactly known for being a match winner. But that can be over come some what with careful ammo selection or hand loading.
Groups were shot from bags using iron sights only. I did not have a carrying handle mount available to me for mounting a optic for precision shooting so I was limited by my own eye sight, iron sights and distance. Real accuracy with most 7.62×39 loads becomes iffy pat about 200 yards anyway and I feel it was reasonable to not shoot beyond that anyways. Handloads, factory loads and import wolf was used above for testing. This hsould give a good indication of what the gun can do and what the ammo can do depending on quality and care put into it.
I did shoot at the steel gong below at 300 yards using the iron sights and wolf ammo. All shots stayed on the steel plate. Very acceptable combat accuracy.
These 7.62×39 carbines are sweet little guns. Again, I think it was a little ahead of its time. Back then no one wanted an AR15 in x39. Especially for hunting. Most everyone was still stuck on the stupid idea that you have to use something at least .30-06 class to kill a 90 pound deer. Not that we don’t still see that today. Add to that 556 ammo was dirt cheap back then and AKs could be had. so why buy what would be considered like a premium gun just to shoot commie crap?
Now, this model isn’t the only one Colt offered. There was a 20 inch( R6851) barreled rifle with A4 “flat top “upper. There was also a flat top upper carbine ( R6850) which was sold as a complete gun or sold as the upper only as a “conversion kit” The conversion kit uppers are the ones you may have seen with “Colt 7.62×39 roll marked on the left side of the receiver. The two conversion kit uppers came with a rifle scope and mount.
If you want one of the Colt 7.62×39 carbines and can’t find the conversion kit upper models and you plan on using it, I would not hesitate to just buy a Colt A4 upper receiver from Brownells and put the barrel on it. Yes it will ruin any collector value but If you want it bad enough.. One of the flat top models with an ACOG would be one heck of a short range hunting carbine for any game you wanted to hunt and would make a nice choice for defensive use if you are one of the unwashed who still thinks the 5.56mm won’t kill a man. Recently some Colt 6940 uppers chambered in 7.62×39 have turned up for sell online. That would really be the ultimate AR upper in x39 as far as I am concerned. As you likely know I am 100 percent sold on the Colt monolithic upper guns. The free floated barrel with the 6940 barrel nut would bring out all the accuracy that could be milked, I would love to see what one would do with good ammo.
