what is the difference, does one make your gun shoot
faster? is one more reliable? what are the advantages
and disadvantages?? read many threads but nobody
explained why, just explained which one they like.

The short answer is cyclic rate. Heavier the buffer slower the cyclic rate. Sometimes a heavier buffer can cause FTE with under powered ammo. Hope this helps.

what does ftp mean, and what happens if you have
a heavy spring and light buffer??

Failure to eject. The H2 buffer is said to stop bolt bounce in Full Auto.

the h2 buffer does cycle slower than the
h right??

The heavier the buffer the lower the cyclic rate.  This can be beneficial in full auto and some say it feels like it reduces recoil.  If you go to heavy for the load you are firing the gas diverted to the action won't fully cycle the weapon.  The heavier buffers are also normally made with more expensive materials (like tungsten) which increases cost.  

Yes, the H2 is heavier than the H.

does it make the gun more accurate or less wera on the
gun?? why do some guys use 9mm buffers?? thanks
in advance

0% accuracy, 100% reliability, unless you consider cyclic rate accuracy(since a low cycle rate makes it easier to hold on target).

it depends on the gun.  a 16" carbine has a lot more pressure than necessary so the heavier the better.  if your running a correct length(rifle gas with 20" or mid gas with 14.5" than you gotta experiment to find what your gun likes best.  If you have no problems, id leave it as is.

The standard buffer spring and H buffer will mostl likely give the best balance of reliability and shooting qualities.
I tried a heavy spring mated with an H2 buffer and it induced malfunctions.  I' suppose I'll try it with the stock spring and the H2 but the rifle runs like a top with the standard spring and h buffer so why mess with success?
