Would be great if it does accept AK mags.

Supposedly it does...and while I am satisfied with my VZ.58, this is a pretty neat rifle. Personally I am not a big fan of AK mags, because they lack provisions for a standard LRBHO, but I am convinced that AR magazines modified for 7.62x39mm is NOT the answer.

Is there a new 7.62x39 round out that is hard hitting? Something better than the mediocre-to-poor performing 7.62x39 that's out there in the real world?

And a Sig 556 with an AK bolt in it that takes AK mags is . . . um . . . basically just an AK with a left side safety? An improvement, but spending money on QC rather than expanding their product line might be a better way to roll for Sig USA these days.

As far as factory cartridges, the Hornady V-max load should perform nicely, and Ulyanovsk 8M3 works fairly well on the cheap (if you can find any), as does Brown Bear (Barnaul) heavy SP.

I simply meant compared to the Sig556 in 5.56

It's not new, but it definitely hits harder than 5.56

The 7.62x39 round is very sound. Nothing wrong with its accuracy or hitting power. It's equivalent to .30-30, one of the most popular deer calibers in history. That said, this gun sounds like it's going to be a freak of nature. It'll be interesting to see how it plays out. And it'll be more interesting to see if they offer an AR mag adapter for it.

And it'll be more interesting to see if they offer an AR mag adapter for it.An Anti-Reliability mag adapter...why would they ever do that? ;) You have to admit the 7.62x39mm AR magazine variant has a history that is spotted at best.

"spotted" come-on your being modest, they are JUNK...

*No real fault to the quality of the mags, its just that the case taper and mag well just don't work together, they weren't designed to.

I'm fairly certain it would be possible to redesign the AK platform such that it would both have modernized ergos and accessory support, and come in at well under "fifteen to seventeen hundred dollars." Jeezus.

I will never understand why SIG prices stuff as if they spray every firearm with 24-karat unobtainium before it leaves the factory.

That hasn't really been my experience in the real world, but to each their own.

"spotted" come-on your being modest, they are JUNK...Pretty much, and you are right; they just aren't designed for that case...5.56NATO, et al, work just fine.

That hasn't really been my experience in the real world, but to each their own.I don't get paid to shoot at people, so i'll not argue that case, but i'd be wary of using a .223Rem./5.56NATO for deer/hog, and have no objection to using the 7.62x39mm (with properly constructed bullets). That is my basis for comparison, others may differ.

My son had now taken 3 white tail with three shots from a 223 (one with a Mini-14 and two with an AR). 64gn soft points work just fine, and there is no substitute for shot placement.

The low recoil of the 5.56 means he is not intimidated by the gun and is really focused on putting the bullet in the right place. Deer took a few steps and fell over. About 80 yards.

As with any tool, understand the operational parameters and limitations.

BTW, 7.62x39 is only equivalent to 30-30 if you are talking about light, flat point bullets and ranges over 150 yards or so where the superior BC of the 7.62 spitzer starts to be an advantage.

Like it or not it beats the heck out of the 5.56NATO/.223Rem.
Tell that to the Soviets, they ditched 7.62x39 in favor of a 5.56 twin, the 5.45 back in the 70s. The Chinese have done the same thing with the 5.8. Ok, maybe ditched is the wrong word, maybe "taken out of front line servce".

The 7.62x39 round is very sound. Nothing wrong with its accuracy or hitting power
No argument there

LOL, a 7.62x39mm sig556. What a pile of crap.

It's basically an AK and you're probably going to pay double price over a good quality 7.62x39mm AK.

On top of that, it's still going to have QC issues. Still has no chrome lined barrel.

People will get excited about anything.

That hasn't really been my experience in the real world, but to each their own.

Let me introduce you to expanding/fragmenting 7.62x39.
It actually imparts quite more energy, momentum, and overall tissue disruption
than any 5.56/.223.

I want to see .223 vaporize that much quantity of water just to gauge a decent comparison. I have not found such but am still looking.
It hasn't been my experience in the real world. And, I have shot many containers of the same quantity of water with M193, all types of .223 hollow points, and all types of .223 soft points.

Yep, I know why am I even bothering to defy physics with a smaller caliber.

Yep, 7.62x39 150 grain softpoint at 2300 fps in a factory load would be as heavy or hot as it comes?

My son had now taken 3 white tail with three shots from a 223 (one with a Mini-14 and two with an AR). 64gn soft points work just fine, and there is no substitute for shot placement.Didn't say that it couldn't be done, just not my choice for the task.

BTW, 7.62x39 is only equivalent to 30-30 if you are talking about light, flat point bullets and ranges over 150 yards or so where the superior BC of the 7.62 spitzer starts to be an advantage.No argument here, it is not as powerful as the .30-30Win., nor does it have the penetrating capability (unless using non-expanding ammunition).

Tell that to the Soviets, they ditched 7.62x39 in favor of a 5.56 twin, the 5.45 back in the 70s. The Chinese have done the same thing with the 5.8. Ok, maybe ditched is the wrong word, maybe "taken out of front line servce".The USSR adopted the 5.45x39.5mm for lighter weight (more cartridges for the same combat load), as well as better controllability and accuracy. Power had nothing to do with it. The 7.62x39mm is unquestionably the more powerful cartridge, and the 5.45x39.5mm is not a ballistic twin of the 5.56NATO, it is in every way (save for bullet design) inferior to the 5.56.

Wonder what the market is for this?

I'm sure they will sell a few to gun collectors. Price will probably rule out the Average Joe shelling-out a whole paycheck for one.

Is there really a police or military market for such a thing?

Is there really a police or military market for such a thing?I highly doubt that they will make the move away from the .223Rem./5.56NATO to anything else, any time soon.
