Yes.

Google .22 long rifle, and look at a picture of that round. Its really teeny, kinda cute.

Then google .223 remington and or 5.56x45 nato.

Let us know what you find......

Try dpms del-ton and maybe bushmaster. They are all good and are relatively inexpensive depending on where you look.

My bushmaster M4 Flat top cost me 880$ total. Just enough to mount a cheap scope for instant gratification. Then overtime, I changed what I didn't like and kept the rest.

No is the receiver smaller? I know the round is smaller.

The 22 lr is not a impingement system, it is a blowback, like a pistol. They do however make a blowback bolt carrier group that can be dropped into a 223 upper to shoot 22 lr (with a 22 magazine obviously). I have never used one but I am intrigued by the idea.

Oh I didn't know I have no experience with semi-automatic .22s

Someone please correctly if I'm wrong, but the lower receiver also is different on the M&P15-22, enough so that it will not accept a standard ar15 upper and cannot be used for that application (without major modifications (cutting drilling cnc'ing))

Well... Some of the internals are polymer in the M&P15-22, like the hammer, as well as the receiver it's self.

This is correct if you want a .223 buy a .223 , if you want it to be able to shoot .22lr buy the bolt and mag kit and make it happen .

You will not be able to convert any of the semi auto .22lr Black rifle types to .223 its just not going to happen , barrel isnt of right caliber, no gas tube or place for one, upper is not made for BCG unit to fit , no buffer or spring , the lower parts I am told are not mil spec and most do not fit it .

So would the trigger, hammer or selector be compatible between .223 and dedicated .22lr
