Well, rifle systems have a lot heavier buffers which reduces recoil (actually just spreads out the impulse) in one sense, but now you have more reciprocating mass slamming forward.
Load power and bullet weight dictate the recoil level. Heavier buffers will slow down the recoil impulse and will often feel like less recoil, but the overall net recoil is the same.
I took my 16" carbine buffer rifle and my sons 16" rifle with an A2 rifle buffer to the range today.
The recoil feels different. But, I could not see any real difference in recoil. The dot jumped the same amount on each rifle.
No real difference in split times.
Watch some videos on bolt/carrier bounce. That might be the difference you are feeling.I took my 16" carbine buffer rifle and my sons 16" rifle with an A2 rifle buffer to the range today.

Everyone knows this.
So if you have a 20" rifle with a collapsing stock, or a 16" barrel gun with a fixed stock, what buffers are you supposed to use?Don't mix your buffers. Carbine buffers for carbines, rifle buffers for rifles. You can damage your weapon and make it malfunction in crazy ways with the wrong one.
