What Ammo?

[kuzmajr]

Was reading owners manual and looking on You Tube and from what manual said caliber should be stamped on the side of the MP15 or on the barrel. I have checked both spots and found nothing. Barrel looks like it might have been changed and there is no calber designation on the reciever. I got this from a friend and was also given a full box of ammo .223. When looking on the web it looked like guys were shooting 22LR, can I do that or is there a modification to the reciever that would have to be made?

Thanks,
Ed

If you have a M&P 15-22 it would be clearly stamped "M&P15-22" on the left side of the lower receiver just in front of the safety lever. Just below that you would see the cartridge designation "22LR". The 15-22 is a dedicated 22LR built on the AR platform. It is in NO WAY capable of firing a .223 cartridge. If you look at your gun, and look at your mags it should be pretty easy to figure out what you have. ARs may not be stamped on the lower, because they are modular and you can put different uppers on the same lower. There are kits available that let you shoot 22LR out of your .223 / 5.56 AR but it doesn't sound like that's what you have. I would say why not just ask your friend what he gave you. I was reading your other post's as well, and I would strongly recommend that if you have any questions, or any uncertainties as to what kind of rifle you actually have, you should take it to a local gun store or shooting range and have someone with experience check things out and show you how to operate the weapon. The last thing you want, and the last thing we want, is for someone to get hurt. Either that, or you need to get a mess of pictures posted up here so members can see what it is that you have.

Exactly what I plan on doing. My friend should be over today and I can ask him and I plan on hitting the local gun shop to find out more info. The last thing I want is to get hurt, just sucks sitting here looking at it an not being able to shoot it.

Was looking through the pics thread and noticed some were labeled 15-22, mine only says MP 15, does that mean anything?

^^^M&P 15 is a .223, take a pic for us and we can be able to tell easier what you have.

It means it's not a .22 and since your friend gave you some .223 ammo that's likely what it is.

Be careful when you go to the gun shop. Go inside without the gun(empty, cleared and cased, magazine seperate) and ask them how you can comply with the shop's rules. They will appreciate it and will tell you how to proceed.

You can break open the gun and look at the chamber. If it's a 15-22, the hole will be the size of a .22lr cartridge. If you can drop one of the .223 cartridges in the chamber(much bigger hole) and it goes all the way in until it headspaces, then it's likely a .223.

Good luck. Be safe.

See if the .223 round fits in the clip, if it does,it's a .223.

No clip its a mag

I say tomato, you say tomahto.
It's a clip. All repeating arms have magazines, not all have clips. The magazine is an integral part of the firearm. A clip is a device that contains the ammunition, which is then inserted into the magazine. I know that the distinction has become confused over the years. But it is what it is.
You can call it a mag if you want.

Wow this forum is awesome, you guys have responded much more than I thought. I am a hunter but have only used shotguns and have a 9mm that I have had for a number of years and have only shot a couple of times. Thanks again for all the great advice.
I have another question, I have a small stack-on gun safe that secures my shot guns and muzzleloaders and have trigger locks on them, is there a better way to secure the MP 15 and the other hand guns I got along with it? Trigger lock, cable, in wall, etc. I do not have a lot of money and have 2 small children, SAFETY is number ONE.
Thanks,
Ed

Yet, everywhere you buy them they are called magazines. The S&W website calls them magazines, and the owners manual calls them magazines as well. And, in this case, as we are talking about an AR, it is definitely a magazine. Clips hold rounds of ammunition together prior to being inserted into a magazine. I would point you to the M1 Garand as an example of rifle which uses a clip to hold ammo together so it can be loaded into the guns integral magazine.

That's right. That's what it does.

Life's too short for me to argue on the internet with someone I don't know about what to call a bullet holder. You can call it a magazine, Wilbur, Tiffany, or Mr. Wiggly. I don't care, I won't tell you what to call it.

I have ran 40gr Blazer and 36gr Federal Champion through mine so far. The Federal held horrible groups compared to the Blazer. Not sure if the weight and rifling are to blame. I will be trying some CCI Mini Mag HP soon. CCI is just so dang expensive compared to 500 rds of Blazer for $19.
