Traditional 7.62x39, I like the kick of AKs in that caliber.
>>
5.45x39. Same price, easier to shoot

That's why I'm asking. I guess I should've included 5.56.

Is .223 less accurate when shot out of a gun chambered in 5.56? Because 5.56 is too expensive, 223 is cheaper.

>>28939441

>>28939363
7.62 for AK pattern rifle, .223/5.56 for anything else.
>>
>>28939363
5.56 you stupid bastard.

>>28939491
>Is .223 less accurate when shot out of a gun chambered in 5.56? Because 5.56 is too expensive, 223 is cheaper.
A .223 Remington or Wylde chamber is tighter in the throat than 5.56x45, which helps a little in accuracy. A true .223 Remington chamber also has a tighter neck.

5.56x45 isn't more accurate than .223 in 5.56 chamber, but both will be more accurate in a Wylde chamber, and 5.56 theoretically can be unsafe in a .223 Remington chamber.

True Remington chambers are rare, however.
>>
>>28939843
So I want a Wylde chamber?
>>
Wylde
>>
>>28939363
7.62x39, 5.45x39, and 5.56x45/.223 are all as close as doesn't matter to being the same price now days.

AKs are best in 7.62, but I say that as a guy who considers his AR to be his go-to rifle. 5.45 or 5.56 AKs just aren't different enough from the (IMO superior) AR to justify me grabbing the AK instead of the AR when planning a range trip.

7.62 provides sufficient novelty that the rifle doesn't languish.
>>
>>28939892
If you want to squeeze out a dollop more accuracy at the cost of a little more fouling sensitivity.

I've got two 5.56 chamber rifles (an HBar profile A2 clone and a free floated 16 inch hammer forged light weight) that will consistently shoot less than 3/4 inch at 100 yards with Gold Medal Match or hand loads (you've gotta shoot slow with the light weight, though, it heats up and opens up pretty quick). I don't think that going 5.56 over Wylde a big deal unless you're really serious about target shooting, or the 5.56 chamber gun is as loose as your mother.
>>
>>28940124
So 5.56 is still better out of a 5.56 chamber than a Wylde chamber?

I would like to get shooting out past 200 yards since I usually shoot .22lr and I would like to have a gun capable of greater distance.

For variety of ammunition available and choice of things to feed it to the order goes: 5.56 > 7.62x39 > 5.45
>>
>>28940171
fouling sensitivity: yes
accuracy: no
>>
Are there any ARs in 5.45?
>>
>>28940254
So if I make a SPR I would be better off with a Wylde but for cqb or general purpose ar 5.56 would be better?

Fuck this shit is complicated. How much more accurate is a .223 chamber than a Wylde chamber?
>>
>>28940288
yes
but see:

>>28940171
>So 5.56 is still better out of a 5.56 chamber than a Wylde chamber?
Qualify better.

If by better you mean more accurate, then no.

But the difference is small, a quality 5.56 chambered barrel will be capable of sub MOA accuracy in a quality rifle. A Wylde chamber is just going to shoot a smaller fraction of a MOA.

I shoot my ARs well past 100 yards, but mostly just at swinging AR500 plates, not at paper, so I'm not going to talk about my 400 meter groups.

I've yet to miss a coyote with my light weight, and my longest shot on a songdog so far was 380.

69 grain SMK anchored him too.
>>
>>28940308
It isn't. But it's tighter in the shoulder/neck, and may cause overpressure with 5.56 ammo.

IF IT IS A REAL .223 Remington chamber. A fuckload of .223 Rem marked rifles have 5.56 or .223 Wylde chamber cuts because the MFG is afraid of liability.

Most people will be best served with a 5.56 chamber. If you want to chase one hole groups with the small bore crowd, you'll want a Wylde chamber, but if the rifle isn't free floated or wearing a match trigger, those are upgrades you will need to unlock the potential of a Wylde chamber.

That's a good question.

It is generally recommended here to "build" ARs over buying them yes? So the M&P 15 sport for instance wouldn't be recommended?
>>
>>28940690
The problem with the M&P 15 is that it's missing necessary component of an AR, like a dust cover and forward assist. At that point you're better off just buying a finished lower, since you will need to replace the upper immediately.
>>
>>28939363
>first rifle
Get an AK in 7.62
Doesn't need to be cleaned as often and is much more forgiving when you do not clean it.
>>
>>28940795
But you really don't need a forward assist or dust cover do you? They seem pretty damn useless.

Nutn says you don't too

>>28940814
Well it's not my first rifle just first centerfire rifle. I've shot family owned .22 rifles.
>>
>>28940843
>Nutn says you don't too
That's pretty much arguing for the dust cover and FA isn't it?
>>
>>28940690
>Recommended to build ARs over buying them.
Yes

>M&P 15 sport
It is OK.
The A2 front sight obscures low optics.
Later you want to upgrade to free float.
>>
>>28940881
Say what you want about nutnfancy but he shoots a lot and he is honest. I can't imagine for a civvy ar 15 that you'd need a dust cover much and definitely don't see why you'd need a FA.

But then again I'm asking here because I'm not that experienced so I very well could be wrong, but nutn makes some good points in his video on the sport.

However if memory serves they did away with the 5r rifling on the new sports anyway, so his version may have been better.
>>
>>28940891
Yeah if I had my choice I'd definitely want flat with flip ups.
>>
>>28940843
Just get a Yugo SKS. It's cheaper than an AK or AR, and some of them still have those neat flip-up night sights.
>>
>>28940690
Yes, but the M&P 15 Sport is a solid rifle. I ended up putting the SI Megafins free float on mine and a Bushnell TRS-25 and it hasn't failed me yet.
>>
>>28940171
Man forget that Wylde chamber vs 5.56 bullshit. You're thinking waaaayyy too fucking hard about it. Either chamber you go with, the guns still more accurate than you are. The only time you need to worry about shit like that is when you're gonna be shooting specific types of ammunition. For instance, if you were going to use GP90 ammo only, and pay the price per bullet and shoot at 600+ yards every time you shot, then sure worry about if u want a bastardized chamber or not. With what you're using it for (non competition) don't worry about it.
>>
>>28940912
>actually watching nutnfancy
How degenerate
>>
>>28940690


The M&P15 just works. Literally the most commonly sold AR15 for like 4 years straight. No complaints, and the gen 2 got a forward assist and dust cover now

If you just want to buy a gun that works, ASAP get an M&P15.

But if you want a specific AR-15 in mind, then just build one to your specific tastes.

It might be even cheaper, but obviously more time consuming.
>>
>>28941044
>>28941063
The AR556 also just works, and isn't missing any critical components, and is in the same price range. And since old man Ruger is dead, they now sell them as standard with 30 round PMAGs.
>>
>>28941092
PMAGS

I'm just a guy with a lot of guns, not any kind of trained professional. If I had just one rifle, all other things being equal, I'd get a nice 5.45 rifle. I've got some AKs and a lot of ARs in different calibers. 5.56 and 7.62 are no slouches but 5.45 is super effective. Everything I've shot with 5.45 has died, and almost all of it has been within a step or two. That's not the case with 5.56 or 7.62x39.

Really 7.62x39 is terrible to hunt with. Even the soft points don't expand worth a shit. I wouldn't want to get hit with it but I wouldn't want to use it in anger unless there wasn't much else. It punches long straight holes in pigs well enough but is terrible for anything else. Heavy 5.56 is much like 7.62 out of most carbine barrels. Light 5.56 is a murder laser on things up to dog sized game but lacks real sticking power bigger than that.

The 5.45 I've recovered from game is nasty and leaves nasty wound channels. Take that for what you will. A 5.45 AK is hard to beat on effectiveness against two and four legged threats, flat shooting, reliability, and handiness.

>>28939363
7.62x39 has more mags and othershit available

also takes care of all my intermidate caliber needs, if i need to reach further I grab,a battlerifle or bolt action.
>>
>>28942136
Yeah knowing the popularity I'm now thinking either .223, 7.62x39 or maybe even a .308 (more expensive but I think it would be crazy fun to shoot a more powerful cartridge like that, and .308 seems to be the cheapest true rifle cartridge)
