Not real familier with AR platform.A local store has 1 of these on rack for 1050$ and plenty of ammo for it, while all the 5.56 and 223 is gone.for a range gun(and varmints maybe) whats the diff? ammo alittle more maybe, but at least still avail here.Worth the money? I know AR pretty much sold out most places.

Are you sure you don't mean 5.45x39? I've never heard of 5.39

Not sure which round you mean, whether 5.45 or 7.62X39. Either of those calibers statistically run cheaper than 5.56/.223. Not a rock river guy, so I'm not sure if that's a good price or not - from what I've seen on the net, it's certainly not a BAD price anymore...

I've never heard of 5.39. are you sure it's not 5.45x39mm? that is the cartridge that was supposed to replace 7.62x39 during the later years in the cold war as an answer the the 5.56 NATO. it's pretty similar to the 223 ballistically and before this panic buying frenzy 5.45 was cheaper than 7.62x39 by a great bit. I haven't seen any 5.45x39 since the scare hit but if yous shop still has a gun and ammo to go with it then that puts you at a great advantage. rock river arms is a great company and do factory direct sales, you just have to pay MSRP for them, if the gun in the shop is more expensive than what they have listed then I would hold off buying it.

Then as said above. If the price is right I wouldn't hesitate. Not much difference in that and the 5.56 x45 and RRA makes very nice rifles.

While the AR in 5.45 will make a decent utility rifle, the mags are more expensive and the accuracy is not as good as the average .223. The only really suitable varmint round is the Hornady 60 grain V-Max. The other choices don't meet my expectations for accuracy or expansion needed for a varmints. The most accurate round in my S&W is the hard to get, expensive, and worst of all-FMJ, made by RWS.
If you're simply buying an AR for the appocalypse, stock up on the cheap surplus ammo and expect to clean your rifle after every use.
I wouldn't worry about the brand name at this point. In fact if that's a determining factor, you probably shouldn't be looking at an AR. Given the availability, any AR that you can pay for and walk away with is OK.

The AR15 5.45x39 mags are hard to come by right now. The 5.45x39 surplus ammo is highly corrosive. What kind of upper is it? Some AR companies building 5x39 uppers are making them with anti-corrosive material designed to handle the russian corrosive ammo. Melonite I believe. I just picked up a spikes pistol upper 5.45x39 for my AR and some ACS mags. I hope they work!

What would be the advantage of owning a rifle in 5.45x39 instead of the way way way way way more common 5.56 Nato/223 ? Or am I missing something ?

Not trying to start an argument, I am really curious about this... ?

I am thinking the same thing, in an AR15 I can see no advantage what so ever in getting it in 5.45?
Maybe cheaper ammo, but the ability to use between 50gr and 70gr projectiles in 223 and better accurcy seems a far far greater advantage the possibly cheaper ammo.

Get a wylde chamber RRA, so you can use cheap 5.56 ammo as well as 223.

what are the advantages of owning a 222 when a 223 is nearly identical but with much more available ammo?

variety, it's the spice of life.

Depends on the OP's intended use of the rifle is and what your wallet can afford. Don't know why so many people keep thinking there is some hugh difference between 5.56x45 and the 5.45x39. You can stockpile alot of Russian surplus AK74 ammo for 1/3 the cost of 223 ammo. That's a pretty good reason. There was plenty of 5.45 ammo available but all that has changed now and the same for the 5.56.

Wolf, Tula, and surplus 5.45 has been a lot less expensive than 5.56 lately. That is the only advantage I see. I like the 5.45 in the AK platform better than 7.62 due to accuracy, and even less recoil. It is almost like shooting .22LR.

It is the cost of ammo.... I understand, thanks !

I didn't think anyone was saying there was any advantage to the 5.45x39 over 5.56x45. It was my understanding that was the only thing the OP could find available and was asking if it there were a big enough difference between the two that he shouldn't buy it. Sometimes it is helpful to read the entire thread or at the very least read the original post.

Slappy is right.I was wondering about diff mainly because that gun is avail now on shelf, along with the ammo.Nothing is around in 5.56.I am thinking it over.I dont wanna buy just on a whim, or panic.I am mainly just curious if this is a common round or if it has any probs/advantages.

The price is decent for a RRA

As for corrosive 5.45 ammo? Am I wrong or is it not modern enough they simply did not make it in corrosive?

Looked it up and it is, amazing. 1974 and why would you, never mind.

I just got an email advertising some surplus 5.45 for $170(?)/1060 rounds. Tell me where you can stockpile .223/5.56 at that price. I bought all I'll need for $225/2120 rounds years ago.
