So what do you have to replace to get it to fire real ammo? The barrel, receiver and the magazine? What's left other than the stock?

Is this like the computer upgrade where you disconnect the power cord from the computer, throw away the computer and put in a new one, but claim that it is just a parts upgrade because you kept the cord? I've don't those to avoid idiots in accounting at some places where you just claim to be buying a few upgrade parts like the motherboard, CPU, case, disk drive, DVD drive and power supply, but didn't want to have to justify a capital purchase of a whole new computer.

I've don't those -> I've done those

Stupid fingers.

You could never get them to fire the real thing.
They only look and feel like the real thing, but they’re actually electrically powered with a lot of plastic. The lower receiver is mostly motors, gears and batteries and the upper has no gas system and couldn’t be modified for a cartridge.

Now, Britain has a problem where metal replicas are bored out to fire real ammo, but it’s dangerous than hell.

Believe me, that has been done countless times (albeit usually in stages) to get past capital equipment approval thresholds.
