school me on AR's

[2000SSM6]

I did mention to them that it was my baby(other than my M4) and that I take better care of it then the military does so it should go home with me!!!

From what I understand the .338L is a much more accurate round than the .50 but doesn't wreck the target as bad either. The .50 just fucks anything up in it's path.

[2000SSM6]

Which ranges at bragg? I have shot on almost all of those ranges!!!

I'd have to call the guy who can get me on, not sure.

hahaha exactly why I like it, doesnt really matter about accuracy when its a machine gun lol, I am sure it doesnt have the distance of a 50 cal round either. The distance on that round is 4.2 miles I know everything about that weapon even all the different types of munitions made for it the military uses the tracers burn out at 1800 meters.

[bluehawk2000]

And if you are lucky when you get to go shoot at fort bragg you might get the opportunity like I got to watch some special forces guys shoot, you can def tell the difference between them and regular army(never wear kevlars when shooting dont wear body armor, walk down range to check targets when their fellow sf guys are still shooting, last they shoot smiley faces in targets hahaha).

Well how much money are you giving us to build this 1000 yard paper puncher?
I mean I could put you in a SAIGA .308 and a $100 Chinese scope and you can punch 4" groups all day at 1000 yards for around $650 bucks.....how much money do we have to work with?

[cuervo25_1]

Hell I was gonna try and steal my m2 50 cal machine gun but they told me they would have to arrest me.

Ask them if you can steal a few ak47's and a shit ton of ammo for them.I will gladly take those off your hands. Tell them you are doing it to disarm the enemy.

[cuervo25_1]

Oh and it sucks that a soldier can't keep soviners anymore, damn political panty waste bitches.

All due respect here Sarge, but I'm tossing the BULLSHIT flag on shooting 1/2 MOA @ 1000 yards with a semi-auto Saiga .308.

I don't care if it has a telescope on it, and your shooting hanloaded rounds that you got straight from Mark Wahlberg while he was filming 'Shooter'.

I think he meant that as a joke. Or at least I hope he did, LOL.

1000 yards with an AR .223 is a pipe dream.....
.308 minimum...
You should be looking into bolt actions for 1000 yard shots.

Yeah....even the best rifles dont offer any kind of accuracy at ranges like that....i think at 600 yards your standard 223 has 5 ft of drop...and im sure the group would be ungodly....the .223 is only good to about 300.

if you wanna go long, look into the 458 socom, or the 6.5 Grendel

[loasdrums]

what does a .308 upper go for? I currently have a 16 in AR-15 with A-1 upper.

I saw somewhere online a site with a .50 upper the was mag fed. My friend and I don't see how they could make it work without moding the lower for the rounds to go through. They had it listed for about $750.

It may not go 1000 yds but Remington R25 could suit your needs. AR styled 308

458S, no. 6.5G, a much better choice than the 5.56.

A .50bmg upper for the AR platform is a single shot only. The mag fed .50 Beowulf upper is more than likely what ya'll were looking at. Shoots a .50 cal bullet but not near as powerful as the .50 bmg.

It's from wiki but still

"5.56mm NATO versus .223 Remington

The 5.56 mm NATO and .223 Remington cartridges and chamberings are similar but not identical. Military cases are generally made from thicker brass than commercial cases; this reduces the powder capacity (an important consideration for handloaders[12]), and the NATO specification allows a higher chamber pressure. NATO EPVAT test barrels made for 5.56 mm NATO measure chamber pressure at the case mouth, as opposed to the location used by the United States civil standards organization SAAMI. The piezoelectric sensors or transducers NATO and SAAMI use to conduct the actual pressure measurements also differ. This difference in measurement method accounts for upwards of 137.9 MPa (20,000 psi) difference in pressure measurements. This means the NATO EPVAT maximum service pressure of 430 MPa (62,366 psi) for 5.56 mm NATO, is reduced by SAAMI to 379.21 MPa (55,000 psi) for .223 Remington.[13] In contrast to SAAMI, the other main civil standards organization C.I.P. defines the maximum service and proof test pressures of the .223 Remington cartridge equal to the 5.56 mm NATO.
The 5.56 mm NATO chambering, known as a NATO or mil-spec chamber, has a longer leade, which is the distance between the mouth of the cartridge and the point at which the rifling engages the bullet. The .223 Remington chambering, known as SAAMI chamber, is allowed to have a shorter leade, and is only required to be proof tested to the lower SAAMI chamber pressure. To address these issues, various proprietary chambers exist, such as the Wylde chamber (Rock River Arms)[14] or the ArmaLite chamber, which are designed to handle both 5.56 mm NATO and .223 Remington equally well. The dimensions and leade of the .223 Remington minimum C.I.P. chamber also differ from the 5.56 mm NATO chamber specification.
Using commercial .223 Remington cartridges in a 5.56 mm NATO chambered rifle should work reliably, but generally will not be as accurate as when fired from a .223 Remington chambered gun due to the longer leade.[15] Using 5.56 mm NATO mil-spec cartridges (such as the M855) in a .223 Remington chambered rifle can lead to excessive wear and stress on the rifle and even be unsafe, and the SAAMI recommends against the practice.[16][17] Some commercial rifles marked as ".223 Remington" are in fact suited for 5.56 mm NATO, such as many commercial AR-15 variants and the Ruger Mini-14, but the manufacturer should always be consulted to verify that this is acceptable before attempting it, and signs of excessive pressure (such as flattening or gas staining of the primers) should be looked for in the initial testing with 5.56 mm NATO ammunition.[18]
It should also be noted that the upper receiver (to which the barrel with its chamber are attached) and the lower receiver are entirely separate parts in AR-15 style rifles. If the lower receiver has either .223 or 5.56 stamped on it, it does not guarantee the upper assembly is rated for the same caliber, because the upper and the lower receiver in same rifle can, and frequently do, come from different manufacturers - particularly with rifles sold to civilians or second-hand rifles.
In the more practical terms, as of late 2009 most AR-15 parts suppliers engineer their complete upper assemblies (not to be confused with stripped uppers where the barrel is not included) to support both calibers in order to protect their customers from injuries and to protect their businesses from litigation following the said injuries."

I got curious about the different rounds. I thought that the 5.56 might be the same as the .223 just labeled different bc one it mil spec verses civilian available. Well, now I know.

Navy SEAL snipers are allowed to engage out to 600 yards with AR based rifles in 5.56.

This is done with a 77gr SBTHP and a 1:8 or 1:7 barrel. Usually a GG&G or LMT piston upper, and Geislle trigger.


Its blasphemy to suggest they have a 300 yard max range.


My AR runs 3/8 MOA @ 100 yards with Wolf 62gr.
That's right, 3 shot group, 3/8".


I guarandamtee it could yield MOA past 300-500 yards with the 75 or 77 grainers.


Also, without looking at a dopebook or drop table, I'm guessing 38-50" drop at 5-600 yards on 5.56.

.308 is likely to be very close to that.

a 308 upper wont fit a .223 lower...its an AR-10, not an AR-15....it will bolt up just fine, but the magaizne for the 308 is too long...it wont fit in the AR-15 lower

Holy hell!!




"Photo of 7.62x51 NATO, 6.5 Grendel and 5.56x45 assault rifle cartridges."

yeah, its a beast, the socom was invented specifically for the battle in somolia, they wanted a big ass round, like a 50 BMG, that could be carried on an AR frame. it was actually developed right here in Dallas Texas.

the Grendel is new, and freakin sweet, each round weighs about as much as a .223, but has more power than a 308...it reaches 1000 yards no problem.

The main problem is though, both these rounds are hard to find, and expensive, reloading is a MUST

Get a 6.8

6.8 is pretty useless, in my opinion its only good for deer hunting, its a necked out .223. it doesnt have any better range, but ammo is more scarce, for any practical purpose of a 6.8, you can also do it with a .223

[loasdrums]

Yep that is what I saw and I saw the rounds on the same site and I can see 1 how no moding is necessary and 2 that there is no way it compares to the .50 bmg. You, sir, are on the money.

[loasdrums]

Maybe a stupid question but can the socom fit through a AR-15 lower?
