I want one of these uppers for hog hunting or whatever. I know ammo is cheaper in 7.62 but the .300 takes AR mags. Anybody here have both who has a preference?

I would consider 6.8 SPC very seriously, out classes both of the above cartridges easily.

If you are set on choosing between 7.62x39 and 300BLK (and not going for another caliber as mentioned above), 300BLK is the way to go, especially if you reload. The ballistics of the 300BLK are very close, and at range a bit better than 7.62x39. You also have access to a much larger assortment of bullets for reloading, including some great options in the 110 and 125gr class for hunting.
Add to that the 300BLK uses standard AR components that are common with 5.56, means you don't have to worry about unique spare bolt parts, hard to find mags, etc. |

Do you reload? It makes a difference.
Do you intend to buy a silencer? It makes a difference. Steel case ammo is cheap and relatively plentiful for 7.62x39mm. Finding boxer primed brass for reloading 7.62x39mm is harder than it used to be. PMC and IMI brass is good but rarely available for purchase. When it appears you need to buy it in quantity for future use. 7.62x39mm is more powerful and a better choice for deer or hog hunting of the two. Magazines usually need to be tweaked to get them running reliably. Metal removal from the front by the feed ramps helps. .300 BO accepts a wide range of common .308 bullets depending on your intended use and will give you a lot of reloading options. 5.56mm bolts are stronger than 7.62x39mm bolts because of the simple fact that they have more metal surrounding the case head. The only thing you need to have is a new barrel. .300 BO is quiet when shooting subsonic ammo through a silencer. Get a pistol gas system if you want heavy bullets to function the action. |

I have both and for hogs and deer, I will take the BO, hands down, put a pistol length barrel on an AR upper and just swap when you need to use the BO easy to reload, easy to make your own cases, just a lot more convenient for the AR shooter.
For pig hunting, it is one of the better rounds to be brought out and the ability to easy run suppressed makes it a favorite. |

Unless you are making long shots, I'd go with 300blk. Lots of benefits with very few detractions. The ONLY reasons to go 308 is for longer shots or you don't reload.
If you reload, you will save $ on powder as a side benefit of 300blk. Also, with the $ you save on buying a whole .308 AR you can get a dillon 650xl because all you need to go 300blk is a dedicated upper to swap onto one of your 5.56. |

I have both.
7.62x39 123 does about 2400 from a 16" 300blk 125 does about 2250 from a 16" Steel cased plinking ammo for the x39 is cheaper than I can reload 300blk with jacketed bullets. It's close but still cheaper. My take, dedicated supersonic hunting rifle, x39 gets the nod. Reloading is a nil factor for performance, better performance can be had from both than factory ammo. Reloading cost is a different story, x39 requires not as easily available .310 projectiles and new brass is expensive and once fired isn't regularly available and more tha .223 converted brass. For subsonic/and or short barreled the 300blk wins easily. I use the x39 as a dedicated steel cased blaster. I have a 16" 300blk Handi rifle and a 10.5" SBR. Needless to say, I shoot the x39 more for ease and 300blk for supressed fun, the Handi rifle is ridiculously quiet. I use the 16" Handi rifle also for hunting, but it would be cool in X39 also. |

If you've got a can, 300blk. If not 7.62x39. If you have a can and reload, take a look at .277 wolverine.

I have reloaded both cartridges for many years. I prefer the 762 since it is a much more forgiving cartridge.
Since the 300 can use the same mag and bolt as the 556/223, accidentally inserting a BO cartridge into a 556/223 rifle is a potential problem. Just my 2 cents. |
|
If you're the type of person who shoots up 300 rounds every time they go to the range, that'd be $150-$200 for your 300 blackout vs like $65 for the 7.62x39. I believe both rounds are capable of killing a deer or hog out to a couple hundred yards. I have both and can say without a doubt my 7.62x39 guns see a lot more action. If you're not gonna SBR and suppress it or load your own ammo, I don't see much point for the 300 blackout.

.300 Blk buy a barrel and you're done.
Ammo costs more than 7.63x39 unless you reload. 7.62x39 Buy a barrel bolt and magazines. Bulk ammo is cheap. Bullet selection not quite as good as the .300. Reloading takes tougher to get or expensive brass. Magazines are iffy compared to standard AR mags and may require tweaking to work. Bulk ammo is cheap. 6.5 Grendel Buy a barrel bolt and magazines. Bulk ammo is not as cheap as 7.62x39 but is affordable. Bullet selection is good. Bullet selection is amazing if you reload. Magazines do not require tweaking to work. Ballistics are superior to both the .300 and the 7.62x39. It's long range performance is what got the party stated. It works at close ranges too and works well from rifle length carbine length and sbr length barrels. Bulk ammo is not as cheap as 7.62x39. |

I really appreciate the feedback here. Since I don't reload and not really interested in a silencer I think 7.62 is the route I want to go. Now to find a quality 7.62 complete upper
|
|
Not sure what kind of "quality" you are looking for but I just bought one from Midway for $280 complete.
Got good reviews. I also ordered an enhanced firing pin. Dave N |

A lot of good suggestions. Like many have mentioned they are almost the same in performance when comparing supersonic.
300 blackout has much better ammo choice and the only RELIABLE option in the ar15 platform imo. The 7.62x39 uppers have gotten better as have the magazines but still nowhere near on par with 300 blackouts reliability/dependability. ammo cost is nil as either hunting rounds are costly. |
|
The only reason I dont have a 300BLK upper and do have a 7.62x39 upper is I have a boatload of cheap commie ammo. Once thats shot I'll likely retire the bolt/barrel/mags and switch to 300BLK.
|
|
300blk is awesome and so versatile, but the cost. I hope it gains in popularity so the ammo gets a bit cheaper.

I bought a model 1 upper today cranked 75 rounds of steel Russian stuff and it ran flawless! I'm kind of an AR snob everything I have up to now is LMT Colt or BCM but this upper really impressed me. It came with the enhanced firing pin, I bought 2 asc 30 round mags and put it on a stag lower. Any suggestions from here? I should have gotten into a .30 cal AR long ago.

I bought into the 7.62x39 in the AR platform a long time ago when we had more than a few magazine manufacturers in the game.
Mags for 7.62x39 can still be had, but are not as easy as 5.56. Bolts will fail early, you will always need to have spares. The stress difference isn't trivial and AR bolts will fail very early due to the extra energy. (The Mutant is one way around this in 7.62x39. You will want one of these too.) Now with the new administration, we may see some of the 5.45x39 come back, and this pressure level doesn't cause early failure in an AR bolt. Also a fun option. With that said, you should get both... life can be short and there is no reason not to have both. All the good reasons stated above on the 300 BO are reason enough to have one, and the 7.62x39 is also too much fun in an AR. |

If you want a cheaper plinking round and a decent hunting round get the 7.62 You got that backwards. If you want to shoot thousands of cheap plinking rounds with poor accuracy a year you can go with the 7.62X39. If you want a gun that can do the same thing as the 7.62X39 and uses the exact same bolts, mags and even the same cartridge just cut down then go with the 300BLK. If you wan't to buy special mags, Bolts that were never meant to be run in an AR and often don't last or special lowers then go with the 7.62X39. The 300BLK gives you nearly the same ballistics while offering you a lot more options on ammo especially for hunting. Plus when it comes to hunting bullets the 300BLK hunting ammo tends to be cheaper, has more bullet options and is easier to find. An added benefit of the 300BLK that the 7.62X39 can't do is subsonic. |

I'm down with people buying whatever guns they want but IMO it's a fairly easy choice.
If you like AKs get a x39 and be happy. If you like ARs buy the BLK. The difference between the cartridges ballistically is practically nothing from 16" bbls |

What is the mutant? View Quote The Mutant is an "AR like" platform that was specifically designed for the energy level of the 7.62x39 and takes that cartridge as a baseline. The energy level of the 7.62x39 is between ones like .308 and 5.56, so it fits in a niche level roughly like a .30-30. Because the 7.62x39 can fit into the AR platform folks do it all the time, however the stress levels on the bolts are high enough to cause premature failures. The Mutant parts look like the middle ground between the .308 sized parts and the 5.56 sized parts, which also means it is specific platform of its own. While all of them use many similar and common parts, there are also ones that are unique and non-interchangeable. But, like I said earlier... Life can be short, if it makes you happy and it isn't being irresponsible with respect to your family economy, why not have this one too? |
