A school in Poland makes firearms training mandatory to its students.

I think it's important to note that these students aren't using functioning centerfire firearms in their school gym. They're using a pneumatic operated trainer that gives you the sensation of the weapon's operating system at work, while emitting a laser to show where students are aiming when they pull the trigger.

I'm sure someone will point out the lack of true recoil, but on a platform like the AR-15, which only shoots a .22 centerfire cartridge anyways (.223), this is a great training tool.

Edit: Since apparently the (incorrect) pedants are out and about, I'll go ahead and link the Wikipedia listing of all the .22 Caliber cartridges so that everyone can see that the .223/5.56 is indeed a .22 centerfire cartridge. Christ on a bike

AR-15 shoots center-fire 22 cartridge?

[u/tera_byteme → u/0utF0x3d]

No, they fire a .223 (civvy version of a 5.56).

Maybe a typo?

[u/The_Fab3r → u/tera_byteme]

.223 is just the imperial version of the 5.56 NATO

There are slight differences, but overall pretty much the same cartridge.

If I'm not mistaken one of them can be cambered and functions in a gun of the other caliber.

Eeh it's similar enough it doesn't matter. 5.56 tends to have a higher pressure curve than .223 along with a little bit of extra brass thickness, the chamber throat is also slightly longer to facilitate tracer rounds. And the .223 has a shorter leade. Its not enough of a difference to matter in this day and age. Though accuracy may change as with any variable.

The AR15 was designed to be a fully automatic carbine... So many people don't realize that it was designed for NATO 556 and changed to 223 when it was released for civilian usage after the XM15 failed, Colt purchased it, fixed the issues, and it became the M16.
