The Colt 7.62X39 Carbine ( R6830)

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.

  1. I remember reading about those in old gun rags in the barber shop. A more scary looking, more accurate Mini-30.

    Those old Colt adds were always pretty cool.

  2. Great article.

    I finally ordered a few C-Products Defense 7.62×39 magazines today. I hope to get my 6940 7.62×39 upper the range in the next couple of weeks.

  3. I bought a flat-top conversion kit years ago. I live in CA. (too bad for me) so I need to remove the flash suppressor and install a muzzle brake. I removed the flash suppressor thinking it would be the standard 1/2 X 28 thread. It is not. It is 1/2 but the threads are finer pitch, I’m guessing 1/2 X 32 or something? Does anyone know the thread pitch and where I can get a muzzle brake for it? Can’t use it with a flash suppressor in CA.
