gas piston
 
Can a gases piston upper work on a normal lower?

All other things being equal, yes.

Yes sir they can,you have to have a hydraulic buffer

Why would he need a hydraulic buffer?

The cycle rate is drastically different then direct impingement gas systems even when firing semi auto you will have problems if your running a regular buffer and spring

What will a hydraulic buffer do that an H2 won't?

They slow the cycle rate and manage recoil better. The added mass and dynamic of the gas piston affects both, so its needed to balance the system.

And what should I tell myself about the LWRC in the safe which runs a H2 and shoots extremely smooth? Should I run out and purchase a hydraulic buffer and add more moving parts and increase the chances something will go wrong?

If you have a LWRC I wouldn't worry about it then but if your building a AR piston driven upper that's a different story

He never said he was building one. He asked if a "normal" lower would work on one. Regardless what would the difference be?
