    Not sure if any of you live in central illinois but I went in to Scheels late last night before they closed and they were stocked to the brim with PMAGS 30 rd. I purchased 6 just to have some more. i am sure they still may have some in stock today.

    Just called scheels, they said they'll be lucky to have them another 1 - 1 1/2 hours. At $25 a pop I'll pass the 15 minute drive to get there. I've got 17 on the way already

    Not sure if you know or not, it is OK to shoot .223 out of a 5.56 upper but you should not shoot 5.56 out of a .223 upper. Just a heads up if you didn't know.

    I did not know that. Cabelas sold out before I could get back there. Actually they said they sold them all in the morning. I was number 5 in line this morning so I certainly would have been able to buy one but my 7 yo daughter was with me and standing around waiting is not her thing. When i do get one i guess I will buy a 5.56 since it is more versatile. I had wondered what the difference was between the two. I know we shot the 5.56 out of the m16 A2 when I was in the corps. Are AR's as easy to break down and clean as the M16's were?

    An AR is the same thing pretty much without the three round burst. Break down and weapon manipulation is same as a2

    there is absolutely no difference between .223 and 5.56 its exactly the same round as a competitive action rifle and pistol shooter I hear this a lot. But 5.56 is the NATO/military designation for .223 just like .308 being called 7.62 x 51 NATO both are exactky the same exact round

    sorry let me clarify my previous statement in ar-15 rifles it is not an issue I would not recommend shooting 5.56 in a .223 bolt action rifle maybe this will help explain it better,


    There always seems to be a lot of confusion over the difference between a .223 and a 5.56 chamber. Is it safe to shoot this? Is it safe to do that? More confusion is added when some manufacturers advertise rifles with .223/5.56 chambers. I found this 'excellent' explaination on Wikipedia (http://en.wikipedia.org/wiki/.223_Remington) and wanted to share it on this forum.

    The .223 Remington is a sporting cartridge with the same external dimensions as the 5.56x45mm NATO military cartridge. It is loaded with a .224" diameter, jacketed bullet, with weights ranging from 40 up to 90 grains, though the most common loadings by far are 55 grains.

    The primary difference between .223 Remington and 5.56 x 45 mm is that .223 is loaded to lower pressures and velocities compared to 5.56 mm. .223 Remington ammunition can be safely fired in a 5.56 mm chambered gun, but the reverse can be an unsafe combination. The additional pressure created by 5.56 mm ammo will frequently cause over-pressure problems such as difficult extraction, flowing brass, or popped primers, but in extreme cases, could damage or destroy the rifle. Chambers cut to .223 Remington specifications have a shorter leade (throat) area as well as slightly shorter headspace dimensions compared to 5.56 mm "military" chamber specs, which contributes to the pressure issues.

    While the 5.56 mm and .223 cartridges are very similar, they are not identical. Military cases are made from thicker brass than commercial cases, which reduces the powder capacity (an important consideration for handloaders), and the NATO specification allows a higher chamber pressure. Test barrels made for 5.56mm NATO measure chamber pressure at the case mouth, as opposed to the SAAMI location. This difference accounts for upwards of 20,000+ psi difference in pressure measurements. That means that advertised pressure of 58,000 psi for 5.56mm NATO, is around 78,000 psi tested in .223 Rem test barrels (SAAMI .223 Rem Proof MAP is 78,500 psi so every 5.56mm round fired is a proof load, very dangerous). The 5.56 mm chambering, known as a NATO or mil-spec chambers, have 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 chambering, known as the "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[2] or the Armalite chamber, which are designed to handle both 5.56 mm and .223 equally well.

    Using commercial .223 cartridges in a 5.56-chambered rifle should work reliably, but generally will not be as accurate as when fired from a .223-chambered gun due to the excessive leade. [3] Using 5.56 mil-spec cartridges (such as the M855) in a .223-chambered rifle can lead to excessive wear and stress on the rifle and even be unsafe, and the SAAMI recommends against the practice.[4] Some commercial rifles marked as ".223 Remington" are in fact suited for 5.56 mm, 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 ammunition.

    You say this in this post but then completely contradict it in the next post, actually backing what I originality posted.

    If it didn't matter why would Windham Arms make the same rifle chambered in the two different designations? I certainly do not know this based on experience but have heard it enough from reputable sources to follow it. I would err to the side of caution and follow the recommendations of the manufacturers.

    sorry buckeye, I had failed to clarify my response in the first post. it wasn't intentional or to be contrary to your original post. in the ar type platform was what I should have specified in the first post guess an edit of the original would have worked better for me

    Were these actual Pmags made by Magpul? Or were they a different brand like ProMag? I have heard some less than wonderful reviews on the ProMags... tho' I've never used one. And to fair if you need one, an iffy magazine is better than none at all. :)

    Hey guys a buddy of mine bought a brand new complete Rock River lower LAR15 with a six position collapsible stock, his wife is upset and he asked me if I could sell it for him since he doesn't know much of anything about it. He wants what he has into it, he is not marking it up.

    It isn't cheap but if you want one he has one.

    PM me for the price and details if you are interested.

    Tell him to put it on Craigslist, I've seen $50 poly lowers for sell for $400 on there and chances are someone with more money than sense will pay it.

    Think I may have to get one of the new nail guns, don't think Chicago has banned construction tools yet

    Uppers just keep going up and up, I may be sitting on a 1/2 gun for awhile. Buckeye's lead is at the SHOT show all week, haven't had a chance to ask them what their timeframes will be like along with pricing.

    So what is going to happen with the millions of recently purchased 30 round magazines once all of this settles down?

    What about all the ammo people horded?

    How about all of the AR parts, like lower receivers, upper receivers and bolt carrier groups?

    I would think most of these parts and accessories secondary value will be greatly diminished, after the dust settles of course...?
