I have two build in currently working on and I'm really thinking about doing one of them in 7.62. The ammo right now is easier to find and I thoroughly enjoy shooting 7.62.

I have never shot a AR in 7.62 so I don't know how reliable/accurate they are. Also, would the be any problem shooting steal cased mitary surplus ammo through it?

I'm basically just looking for opinions and things to look out for if I decide to do this.

Mags are- or were, at least- harder to find.

Some folks say "US ammo for US gun; steel ammo for Commie guns", but with even quality US makers like Hornady producing steel-cased ammo now, that doesn't seem like a major issue.

Depending on your hammer/hammer spring, you may get light strikes with imported ammo. Probably want a GI hammer spring or Wolff extra power one.

I hear mags can be iffy for feeding? Anyone with comment on that?

Convential wisdom is the mags have reliability issues although some claim there are reliable ones out there. The best configuraiton i've seen is the Rock River AR lower that takes AK mags. Unfortunatley i don't think they're selling the lowers individually.

7.62x39 is for AKs. Why put yourself through the drama of mag problems, ammo problems and reliability problems when you don't have to?

When 7.62 M43 AR first came out folks used standard unmodified magazines in them but only loaded to half capacity of 5.56 NATO though. Do the newer ones and conversions not work with half loaded standard mags, or have folks just assumed they won't?

I am only even thinking about this because I can't find the .223 or .556 to shoot my current rifles. Why would I want another that I can't shoot? It could be over a year before the ammo starts coming back to the shelves.

If you like the price, then why not go 5.45x39?

In addition to what's been mentioned, they tend to have feeding issues, related to the shape of the cartridge.

ASC LLC 5, 10, 30 round mags work fine

I love my AR carbine. I can shoot anything through it, although I have committed to brass-cased ammo only now, since I have plenty and piles of IMI brass.:cool:

I usually get 1 MOA with the right loads...

If you want a gun with 30-30 performance then get a Marlin or Winchester in 30-30. They are great brush guns and I kill deer with them regularly. If you want .308 performance in an AR then get an AR10 or variant. I kill deer with one of them too. ARs were originally made in .308 and .223. They didn't design then in 7.62x39 for a reason. But its your gun. Do what you want.

I say build it, I am. i dont care to load 30 rounds and go running through the desert shooting at targets. most of my shooting is don in a hunting blind at a little less than one hundred yards. and in my opinion 223 is just not big enough for some of the axis around here.

OK. I'm not saying you're wrong. But the last time I looked, x39 ammo was harder to find and priced crazy too.

Not around my way. I can walk into any shop and get Wolf or Tula for $7 a box. Maybe not a lot of AK/SKS owners in my area.

Rethinking this. If I do go this route, I will most likely go with 5.45x39. I've read very good things regarding uppers configured for this round. It also seems that normal AR mags work good with this round. Currently you can get 5.45x39 for .23 cents a round. Anyone else think this is still a bad idea?

64 gr Power points, 60 gr. Partition, and 55 gr. Barnes Vor Tx beg to differ.

IMO, not a good idea if you're gonna shoot corrosive ammo. I would stick with commercial stuff.

I have four of them. Stoner mags, brass rounds. Accurate and harder hitting than my 5.56s.

I wouldn't want one because that curved mag is ugly as hell sticking out of an AR. Seriously, I love AK's and AR's and have a couple of each, I just can't warm up to that hybrid look.

ARs in 7.62x39 would be the hottest thing going if some one could figure out how to make magazines that were 100% as reliable the average 5.56 AR magazines are.

OTOH if a 10 round Federal magazine limit hits, ARs in 7.62x39 could be the hottest thing going as the 10 round mags are the only ones that seem to be really reliable.

I've a 16" and 11" SBR ARs in 7.62x39 and they my favorites at the range where the occasional feed failure is no big deal.


My 7.62x39 AR proves Wolf ammo is not as inaccurate as the AK makes it out to be:

I have Olympic Arms AR in 7.62 x 39... it is a great rifle... I only shoot cheap Russian steel case stuff... decent accuracy... every pull of trigger makes gun go bang... you can find cheap mags... for maybe $15... I haven't shot it in a while... but not a bad way to go... makes bigger holes than .223 or 5.45 x 39...

Any other rounds I should be thinking about? I'm really interested in the 545x39. Anyone hear anything good or bad about AR's chambered in that round? They use the same mags, right?

The bolt face and the extractor for a 7.62 X 39 is not as strong as a 5.56 bolt face as there is less 'meat' to contain the rim. The quality of consistancy is not as great as 5.56. I know about this because I shot a 6 RAT for a few years which is based on the 6.5 Grendle which has the same bolt as a 7.62X39. I had a dozen magazines and maybe 5 of them were reliable.

I am not saying the 7.62 doesn't work - I am just saying this gun was designed for the 5.56.

rtz - I was just about to post a link to that exact page!

An other thing I will point out is with the generous taper, at least chambering and extracting should be very easy for the rifle.

From what I have read, seems the curved 7.62x39 AR mags have come quite a bit along in reliability. Here's a source. (http://www.ammosc.com/storename/ammunitionstoragecomponent2/ViewDept-273398.aspx) Best of all, they are stainless steel and not aluminum, so they should last a bit longer.

lakecitybrass
March 15, 2013, 02:41 AM
Actually, I have aluminum AR-15 mags that date to a long time ago. It has been the followers that wear but many of the original aluminum followers have held up. My problems with steel mags is that they don't always drop quickly.

+1 on looking at 6.8SPC and 300BLK.

300Blackout has almost the same ballistics as 7.62x39 (close range anyways). parts are easier to find; I know a few places like CMMG still have barrels in stock.

But in my book, stick to 5.56 in AR's and 7.62 in AK's. The 300BLK is the compromise between the 2.

Keep in mind that 6.8 ammo is basically not available and neither are the mags commonly available. I've been looking at alternate chamberings since I'm a little short on uppers right now. I've got BCG for 5.45, 7.62, 6.8, and 5.56 as well as mags for all but no 6.8 ammo so I'm ditching that prospect. If you're just looking for a blasting rifle, the 5.45 is fine but hunting ammo for it is slim pickens. BTW I don't consider the steel cased 5.45 HP to be suitable for hunting and I'm not certain about the Hornady V-Max for anything but varmints.

I disagree with the availability of 6.8 ammo. I've seen more of it at Palmetto State armory than 5.56 ammo. Same for midwayusa. Granted both are out now just as most everything in 556 is too.

Another real good place for 6.8 ammo is Silver State Armory, they make some of the best 6.8 ammo. Federal is close to releasing their 6.8 offerings, 115gr FMJ, and a Gold dot load. Hornady has some great 6.8 loads too with a vmax, SST, and match load offerings.

Right now, midwayusa has 10 rd mags and PSA has 25rd mags.

I love my 6.8 SPC rifle, took a nice buck with it this year using the Barnes 95gr TTSX.

Best wishes and keep shooting!

SSA had some 6.8 ammo in stock a couple of months ago. The website was too busy to let me order that night. Tried for hours.

Was sold out the next morning, except for the most expensive stuff.

I wouldn't build an AR15 style rifle in 7.62x39 too much hassle not to mention personally I think they are a bit ugly.

If you would consider a new rifle a good rifle to look at is a Sig 556R. it's 7.62x39 and offers the best of both worlds

I've gotten 7.62x39 to feed from a .223 AR magazine in a pinch, but it will only hold a few rounds at a time.

They are great but the inexpensive (it used to be cheap :( ) ammo is corrosive and the AR has a lot more nooks and crannies to clean than an AK. The non-corrosive is usually a bit more than Wolf 7.62x39, and at the end of the day the 5.45x39 is Russia's answer to the 5.56 and shoots about the same. You need 5.45x39 AR mags to get full capacity although you can usually get 5.56 mags to feed at reduced capacity.

As to the RRA, its not really an AR as the upper and lower are not standard like the 5.45x39, 6.5, 6.8, 300 Blackout, or 7.62x39 variations are. Although I'd very likely buy one if I could ever find one at a decent price.

The reliability of the SIG 556R doesn't seem to be what most folks expect from SIG. My has lots of Failures To Fire with some brands of ammo, others have lots of feed and ejection problems, but mine been fine it that department.

ive had a bushmaster 762x39 for about 4 years now. Its a good reliable gun. Had some teathing problems at first related to magazines but once i started useing cproducts mags with wolf ex power ak47 springs in them its been about flawless. Thing i like about it is i can buy cheap wolf steal cased ammo take it to camp and blast away and not worry about having to find my brass. I shot a couple whitetail with it and it no doubt hits them with more authority then a 223. If i had to get rid of all but one of my ars this one would stay.

Lakecity,

The original AR was designed for the 7.62 Nato to replace the M-14, not for 5.56. It was re-engineered for the 5.56 when they wanted it to go full auto (M-16).

Well, you haven't looks very hard. 7.62x39 is, at least, half the price of .223 and is widely available right now.

Based on my observations...

Average price of .223/5.56 = 75 cents/round

Average price of 7.62x39 = 33 cents/round

The average price for 7.62 is also cheaper according to my observations as well. Every shop within a 50 mile radius of where I live has 7.62 in stock. I just got done buying 20 boxes of Tula for $6.75 a piece at a local Pawn Shop.

Yes 7.62x39 seems to be more available than 5.56/223 if you know where to look.

I just bought 1k rounds of 7.62x39 online for $350 shipped last month, and some LGS sell them for $8-10/box. 5.56/223 is going for way more than that...
