I just completed my second build which is running a BCM 14.5" LW middy, auto carrier, and carbine buffer. It's the smoothest shooting AR that I've ever shot. My other rifle is running a RRA 16" LW middy, enhanced carrier, with carbine buffer and has a noticeably harsher recoil impulse.

I know the carrier weights play a part in how smooth a rifle feels, along with barrel length, gas systems, and buffer weights. My question is, would going to a heavier buffer help smooth out the 16" middy to be more like the 14.5" middy?

An H or even H2 will make a noticeable difference.  The RRA is probably a bit overgassed.  



My FN 16" mid is butter, even with a carbine buffer.  I did swap in a Sprinco White, and an H and it is really flat!  I tested the new Spikes D2 comp on it today, and it is like a damn .22 with that.



You might try a Sprinco Blue, too

Thanks Alaska. I'm going to start tuning the 16" and see how it goes. I've heard RRA's mids are over gassed, mine seems to be.

I run full auto carriers and "H" buffers in all my M4's and Middys. I shoot mostly Federal M193 , which is loaded pretty hot. Recoil is about that of a .22 lr.
