Hi, the S-system uses a proprietary upper receiver.

To change to a regular m4 you will need to swap the entire upper receiver / hand guards & outer barrel arrangement.
The s-system hand guard is not held on by a spring loaded delta ring like a standard m4 hand guard.

I thought i could do the same with a 2010 JG enhanced s-system i picked up a year or so a go.
I learned the hard way.

Yes you can use the gas block & fold up sights, & the flash hider, and the inner barrel/hopup.

A standard M4 upper will fit just fine on a s-system lower.

Good Luck, Keep us posted

I make 2 predictions;
ON THE DATE WHEN US TROOPS ARE ISSUED AN Energy Pulse Weapon,
1. the US Soldier will have on his person a version of the Colt 1911,
2. and he will be aiming the NEW Weapon at someone carrying an AK.
