You mistake Advertising Force for Engineers. And I am just as qualified as the Engineers in rating the weapon. I look for certain features. If I see them then I say it's okay to fire the 556. IF I don't see them, I say it's not okay. It's better to err on the safe side on this one. Especially when we are dealing with a bargain basement gun in comparison to a real Mil Spec or a Match Quality.
Like I said, Smith m&ps are great Entry level sporting rifles.
Match grade is not expected with entry level firearms. I sell Smith m&p sports for $469, out of the box they shoot 1moa if the shooter is up to it.
Liability issues with Smith? I am sure they have it covered... they can shoot both cartridges just fine.
The reason why they shouldn't has been brought to your attention. As of now, you are culpable should anything happen to anyone firing one of these that you have sold if anyone fires a 556 out of it. S$W might be able to afford millions but I doubt if you can.
You being an metallurgy expert...
I don't expect you to understand since you say that there is a difference between the AR and the M-16. Those of us in the know know that the only difference is the amount of money spent on the gun. And your idea of an AR is strictly bargain basement. I would venture to call them the "Saturday Night Specials" of the ARs. I, personally, like the better quality with the Mil Specs which can safely handle the hotter 556 loads without fear of either damaging the weapon or myself. You sure don't sound like much of a gun dealer outside one that deals out of his car's truck at 2 am in the morning.
Lol
Na, like I said s&w m&p15 sport is a great entry level sporting rifle.
It can easily shoot 1moa out of the box if the shooter is able, An above average barrel.
Obviously it’s no where near military grade... it is very able to shoot both cartridges safely.
But, believe what you want... it’s the progressives way.
Oh, I see. It's Progressive to want safe firearms. It's progressive to demand that the sales pitch for a firearm is truthful. It's Progressive to demand that we get safe weapons? Hate to break it to you but that's Capitalism at it's best. What you want is to make sales to stupid people by misrepresenting the cheap junk as something it's not. Here is what Mil Spec Means for the firing chamber which the MP15 doesn't meet.
The rifle you are pushing has a SAAMI chamber. Which means it's like the traditional chamber. It's tight against the bullet. No room. SAAMI is the standard that all civilian guns have to meet. And the 223 was created in 1962 to meet that criteria and has been frozen to that standard ever since. The Chamber is made as small as possible to utilize as much energy as possible from the lower powered 223 round.
Them we have the Mil Spec. At first glance, this seems inferior because it's not as tight. The reason it's not as tight, it allows more space for gas expansion before the bullet exits the chamber. The Pressure is much higher than the 223. This does not comply with the SAAMI standard and has been changed many times since 1959 when it was first introduced. It's constantly been updated for maximum efficiency.
Can you safely fire a 223 in a mil spec 556 chamber? Sure you can but the downside is, you will lose accuracy and velocity compared to firing it out of a SAAMI chamber that has been optimized for the 223. That extra headspace will bleed off pressure that should be used to propel the bullet down the barrel.
Can you safely fire a 556 Nato Round out of a 223 SAAMI chamber? Most of the time. I doubt if it will ever blow up in your face. But it will slowly degrade your barrel over time. And it will sooner or later have an annoying problem of popping primers into the mechanism which will jam the gun. The popped primer isn't too unsafe, it's just damned annoying. The more you fire that 556 through your SAAMI chamber the more it's going to start happening as the barrel (Chamber) wears. When this happens, it's time to change out your barrel.
The gun that Dipstick is pushing is a SAAMI. It's the bottom of the barrel. If you want a much better rifle that will last longer, shoot straighter, and more, look for these other qualities. But you will have to pay for them.
.223 Wylde, Anything rated as match, Anything rated as NATO. None of these seem to have any trouble with the 556. But the 223 Wilde and anything rated Match also has no trouble with the 223 either. The Nato is specifically tuned to the 556 Nato so it's going to degrade a bit with the 223. The good news is, you might, and I strongly don't suggest this, might be able to fit one of the better barrels to the MP15 rifle. I would suggest you also change out the bolt as well to a better bolt. By the time you get a decent rifle by doing this, you could have bought a decent one for the same amount of money without having to modify it.
When I buy a gun, I expect it to last the next 100 years or so. My Great Grandkids can fire it up long after I am gone and it works just like it did the day it came out of the factory. I don't need to be spending hundreds of dollars on something that will be constantly having to replace parts on to keep it servicable. These are Toasters which I throw away when they break. And they certainly should not be made in China. If it's made in America, I expect quality and should be required to pay for quality. All of a sudden, that Mini-14 doesn't look so bad anymore even if it is a bit more cumbersome to change the mag out on. The Mini-14 costs not much more than the junk AR but it's a 100 year or better gun. I respect that.
So is there a difference between an AR-15 and a Mini-14? For the money, you bet. Buy the Mini-14 and get something your Great Grand Kids will enjoy.
Die of fast!
