| Is it just me or does the 7.62x39 cal AR platform have a bad reputation. I have had mine a little bit now, shot my deer, it eats anything and yet when I tried selling it no one wants it.lol guess its a higher sign for me too keep it instead of changing it to something else. |

Yeah, it has a bad rep, and it's somewhat deserved. It sounds like you have a good one -- keep it. I have one that does NOT like soft-nose ammo at all. FMJ functions fine. The cheap Chinese copper-washed stuff that I bought with my SKS in 1998 makes mine a single shot. The first magazine I got (ProMag) was so badly made that it wouldn't feed anything until I did some surgery. The consensus seems to be that if you get just the right combination of parts, the world is good, but there's no way to know for sure what will work and what won't.
Now that I have mine working and know what it likes and doesn't like I'm happy with it, but it was a journey to get there. |

From the Wikipedia entry for the 300 Blackout:
"Colt Firearms and other arms makers had previously chambered AR pattern rifles and carbines in various 30 caliber rounds but several issues were encountered. In the case of the 7.62×39mm, its relatively severe case angle caused feeding issues unless specially modified AK47 magazines were used and even then results were less than outstanding." |

The thing is some tried to shoot the 7.62x39 using 556 mags 15 years ago and are still telling the story about how it didn't work. Well no shit. Many here are still telling the stories their dad told them yet they have never even seen a 7.62x39 AR. In the last few years USA had the franken mag, it worked. CPs, ASC, CPD mags work pretty well. Every 5.56 doesn't run flawless either, that is why you hear people talking about which follower and springs to use or why Magpul sells as many 5.56 mags as they do. The 7.62x39 may not be the best but it's not the worst either. Try to get a 450 bushmaster or Oly wssm to run full auto. All of the cheap 556 ammo is gone while there is still plenty of 7.62x39 to be found. |
| A lot of the issues are due to the magwell angle on the AR-15. The AK mags have a steeper curve to them, and cannot be duplicated on the AR-15 platform. So you get a lot of feeding issues with AK rounds on the AR platform. Some companies have addressed that like MGI that makes the Hydra AR-15 with interchangable magwells. You can slap on an AK magwell and use factory AK mags on the AR. That solves all the issues of feeding and prevents you from having to buy more mags you don't need or want. |

I agree with liquidmetal. Both my x39 ARs run perfect. I have the same combination of parts on both of them with one being a high dollar build and the other being a low cost pre built upper/lower assembly. I use ASC mags, enhanced firing pins, M4 feedramps, and XP hammer springs in both of them. I do not use SP ammo as it has issues with the ramps in the AR. I feed the low cost one (NFA polymer lower with SOTA arms upper and PSA buffer) exclusively Tula and surplus ammo (cheap crap) with no problems at all. Every round has gone bang on the first trigger pull and I have had no FTF, FTE, jams, or duds. I feed the high end one (LAR side charge upper with Kies bolt/barrel and M&P lower) both Tula and Laupa ammo. It is pretty accurate with the Tula and incredible with the Lapua. If I decide to start hunting again I will just get some of the Hornady zombie ammo since they are just A-max rounds with green tips.
Its the constant regurgitation of the old hype that makes the x39 a hard sell. When someone tries to build one with the wrong parts then tries to run SP ammo through it and cries about it when it doesn't work, all the keyboard armorers on the net puke up all the old crap again. If you find someone who is interested, let them shoot the gun and see for themselves that it works. A couple boxes of Tula for $5 each at walmart and a place to test it would make a great selling point. I actually sell a lot of guns locally and I make the buyers shoot them before closing the deal. I won't sell them without the buyer shooting them so they can see that it works first hand. |
| I agree with all of you, the wring parts equals disaster. That's why I spent time reading and listening to what everyone here said. It worked, I have one that's great. Just wish I had enough money to buy a barrel and bolt for my coyote gun, then u wouldn't sell this. What's max range on a X39, good enough for coyote? |

How does it group? What are your optics? How steady are you?
Not trying to be smart...These are the determining and limiting factors. 
Personally my 7.62x39 is my coastal deer gun. For critters, I took my .223 carbine apart, put on a low rise upper, gas block, free floating hand guard, a 4x12x40 scope....and Wallah!! 
A poor man's varminter.

Jack... Actually I shouldve reworded that..lol It groups abut 1" at 100 yards, Im a good shot and have taken coyotes out to 300 with my bolt guns, I was more thinking along the lines of whats the point were the round starts dropping so much that hold over would really be to much. I used my X39 on my deer this year and I love it. Just hoping for a flatter shootinf round. If I am wrong please correct me I only have experience with this round in my AK for close work. I dont have much experience with it past 100. |

I hear its a bit different because of the AK mags... |

I ran a few mags of x39 today thru my suppressed 10.5
It shouldn't ever work, right? Too bad an older upper I decided to sell had over 3k thru it. I can't forget about the 16" carbine I built too. It runs when the receiver gets M4 ramps and a good bolt. And M1S or Galati Int'l enhanced firing pin. The same goes for the other x39 caliber gun I'm building: the 5.45x39. Correct mags. Correct M4 ramps. Proper firing pin. Shoot and enjoy. |

I'll put it to you this way. Reading or hearing reports of 7.62X39 AR's is like listening to the nightly TV news. It is nothing but bad news. So if you are on here enough just surfing the forum you will see threads about something negative with their 7.62X39. You don't hear about the good stories either about 7.62X39 AR's running 100% or something good or positive in the nightly TV news. It could be related to anchoring which is one of the cognitive biases listed here: http://rationalwiki.org/wiki/List_of_cognitive_biases Anchoring — the tendency to rely too heavily, or "anchor," on a past reference or on one trait or piece of information when making decisions.

Quoted: Both of my x39 ARs are every bit as reliable as their 5.56 brothers and a lot more fun to shoot. Absolutely no issues with either rifle. I usually dismiss the hate towards x39 ARs. A lot of it is BS. your not the norm then, rather an exception. I'm on my 3rd, they are a pita to make 100%. I've had the ak magwell model as well as the normal ar magwell. the hate is deserved whether you believe it or not. You cant cheat physics or stats |

| I've never owned nor shot a 7.62 AR so I won't pretend to know anything other than they do in fact have a horrible reputation. I have never met anyone in person that had anything good to say of them at all. I'm not passing judgment, but when it comes to trying to sell something, perception IS reality |

I own a YHM Carbine in 7.62x39 in the just under 1k rounds I have had through it I have had no malfunctions what so ever this is ASC mags. I think most of the reputation is driven by regurgitated horror stories , based on issues that have long since been addressed.
On Second thought they are all crap and will give you scrap price for your plus 10%

Both of my x39 ARs and had any issues as well. Both had the Model 1 firing and used the stock hammer spring.
Some of my mags where hit or miss. Replaced all the mag springs with Wolff AK springs and always down loaded my mags to about 25-26 rds; it ran well after that. Didn't have any issue selling them both either as they both sold quick(one on here and the other locally). Quoted:
