Anybody have any experience with the Sig 556R 7.62mm?

[Spazzmodicus]

I've settled on the 7.62mm round over the 5.56mm, for more power and punch, otherwise I probably would have already gotten one of the Sig AR-styled rifles. I was looking seriously at the Ruger Mini-30, but the barrel is a bit thin for my liking. May not matter at all. I know the Mini-30's are reliable, although I've never actually fired one.

I just learned yesterday that Sig now has a 7.62mm rifle out, the new "Russian P556R". At roughly $1200, it seems a bit cheap compared to some of the other Sig Rifles. Did Sig skimp on the P556R? What gives? Just wondering if anybody has actually fired the new 7.62mm rifle and any opinions about it.

At more than half the cost, the Mini-30 still looks quite appealing, although it's a different animal altogether I know. Would be interested in hearing about it too if anybody cares to chime in. Thanks for any input.

 

[Spazzmodicus]

Perhaps I should have said "At less than half the cost" about the Mini-30.

 

[cgbills]

Don't know about the 556R, but I know I like my Sig556 very much.

 

[Indy_Guy_77]

Which 7.62 round are you talking about?

7.62x51 (7.62 NATO) or 7.62x39?

They're entirely different rounds.

Since you've mentioned the Mini-30, I'm presuming that you're interested in the x39 version. This is commonly (if incorrectly) called the "AK round"

I think that CZ and possibly a Turkish rifle branded by Remington both make right decent bolt-action rifles for this cartridge.

But if you want 7.62 NATO, you'll find that there are HUNDREDS more offerings in types of firearms. (aside from the "com-bloc AK and AK-style weapons). It's also probably 3x the cost to shoot.

If you get a .308 Win chambered rifle, you can also shoot the 7.62 NATO round through it. (not always is the reverse true. They're SIMILAR cartridges, but not identical)

[Spazzmodicus]

Well, again I must admit my ignorance on ammo. Didn't know the difference between Nato and X39. However, the Sig fires the 7.62 X 39mm. So the Ruger is still in the running...heh heh.

I was at one point considering an AR chambered in .308, but I really want a Sig rifle. So for a die-hard Sig fan, the logical choice would be the P556R. Not sure why they chose a round that might be considered a bit obscure in comparison to the Nato round, other than cost of the round. Not sure.

I think you'll also be disappointed to learn that the Sig556 and the Sig516 rifles are only chambered in 5.56x45 (also called 5.56 NATO) Not at all trying to be a smart ass, but there's a reason it's called the "Sig556"....

Now, the SSG3000 rifle, a bolt-action, IS chambered in .308 / 7.62 NATO...

I suggest you take a few minutes to step back and think about a few things.

* What do you really want? What will leave you not thinking about "why did I buy this one over the other".

* What are you wanting to do with this rifle?
- Fun shoot/Pinking
- Practice CQB/Running and gunning?
- Long range marksmanship?
- Zombie Apocalypse?
- Tactical/Tacticool Ranger BAMF?
(I added the last two for giggles)

*Whats your budget?
-Can you afford this rifle and the little extras you will want. IE Mags and other upgrades?
-Have you priced the ammo of the rifles your considering? 7.62x39 can go as low as $3.59 per box of 20 as where a Nato 7.62x51 (308Win) can go for $6.49. Both prices quoted from Cheaperthandirt.com for Russian surplus ammo. Normally you can't walk out of a store with .308 Win for less than a $1 a round for non Russian. (If your not looking for a .308Win disregard this part)

Give us a idea of your goals and we I can give you some experienced advice.

All ways keep this advice. When you ask a question on the Inter-webby, remember the people giving you advice might be, Ignorant, Stupid, Opinionated, and in a lack for better words "Just talking out of there ass"

I will not tell you want to buy I will just help point out things to think about before you commit to buying.

Sorry, I do not have first hand experience with this rifle, but I will help in anyway I can with my experience choosing whats been best for myself with my own applications.

Sorry to shoot you down Indy but the Sig 556R is chambered in 5.56 nato and 7.62x39.

http://www.sigsauer.com/Products/ShowCatalogProductDetails.aspx?categoryid=35&productid=316No, not disappointed at all. Kinda' excited about it. There might be a reason there is an "R" on the end, as in "P556R". Don't ask me why they called it that as opposed too the "P762R" for example. Click here to see:

This sir is incorrect!!!!! This is how internet rumors get started!!!

The 5.56 and .223 are NOT interchangeable.

However the 7.62 x 51 and the .308 ARE interchangeable.

If you can prove otherwise I would be interested in seeing this.

Sig has a 7.62X51 in their Line-Up

SIG SAUER presents the long awaited SIG716 Tactical Rifle line for Law Enforcement professionals and civilians. Chambered in 7.62 X 51 mm (.308 Winchester), the SIG716 Tactical Rifle line is built with the tightest tolerances, making these rifles some of the most accurate and durable AR-10 type models on the market today. The SIG716 rifles are gas-piston operated with a 3 round-position (4-position optional) gas valve – a design that keeps the receiver free of firing residue for optimum reliability under adverse conditions and extended firing. The SIG716 select-fire modes include single-shot, 3-burst, and fully automatic (Law Enforcement only). The fire control/safety selector is an ambidextrous design for easy accessibility and improved safety.

That .308 sig is still vaporware.

Furthermore, why in the world would sig NOT produce a rifle along their 55X line instead of making another AR?

Darn sig.

Long range shooting/fun/pinking for now. Part of my SHTF defense for later.

Actually...

One can fire .223 Rem in a 5.56 chamber. Generally, the NATO round of this caliber is higher pressure than the "civilian" round.

And one can fire 7.62 Nato in a .308 chamber. Generally, the "civilian" round of this caliber is higher pressure than the NATO round.

You can generally shoot the lower pressure variant without any problems what-so-ever.

And because the differences are rather slight, many makers just go ahead and make their firearms safe for both without actually stamping it on the bbl / receiver. (Case in point the Ruger Mini-14)

.223 Rem and 5.56 Nato are very very similar cartridges.

and 7.62 Nato & .308 Winchester are very very similar cartridges.

When you really study it, the lines between the 5.56 Nato & the .223 Rem get blurry. One's measured in CUP, one measured in PSI. They're not equal measurements. Also, they're not measured on the same place on the cartridge.

I'm quite certain that the differences between 7.62 Nato and .308 Win are greater than for 5.56 Nato / .223 Rem

As far as the above Sig 556 rifle being available in x39... Sweet! I looked through Sig's website and I didn't see it listed! Of course, upon double-check, it's the last one in line. So, thanks for correcting me on that one.

Actually...

And one can fire 7.62 Nato in a .308 chamber.

But the reverse is not always true.

.223 Rem and 5.56 Nato are very very similar cartridges.

and 7.62 Nato & .308 Winchester are very very similar cartridges.

Again with the misinformation, unless you have facts to back this up I call Bull****!!!

Every institute has said 7.62 and .308 are completely interchangeable.

You are once again confusing the information about 5.56 and .223 with 7.62 and .308.

 

[Indy_Guy_77]

Dude, listen to me:

I am NOT SAYING THAT THEY'RE INTERCHANGABLE.

I AM SAYING THAT YOU CAN GENERALLY SHOOT THE LOWER PRESSURE CTG IN THE CHAMBER DESIGNED FOR THE HIGHER PRESSURE CTG.

IE, .223 in a 5.56 = OK
IE, 5.56 in a .223 = NOT OK.

 

[Andre46996]

Yep I agree with that, but what about the .308 we were talking about... I never disagreed with the 5.56 in 223 bad. 223 in 556 ok

 

[Indy_Guy_77]

.308 Winchester =/= 7.62 Nato

They're similar. But NOT identical.

7.62x51mm NATO or 308 Winchester? What's the Difference?

The Gun Zone -- .30 Caliber Ammo

.308 Winchester vs. 7.62×51 NATO | The Firearm Blog

.308 Winchester vs. 7.62x51mm NATO
So it may not be a pressure issue at all (As I alluded to in a much earlier post), but related to a headspace issue



SAAMI considers it safe to fire the NATO round in a .308 Win chamber.
