Along with the Sprinco M-4 Carbine Extra Power Buffer Spring (Red), I have this ST-T2 buffer installed in my 6.5 Grendel.Both items really helped reduce the recoil of the said rifle.

Spike's ST-T2 Tungsten Heavy Buffer
by BOB PRESLEY
The ST-T2 is just the right weight buffer you need with a AR to help with smooth cycling. And yes it does stop the buffer noise somewhat.
Great when you shoot short barrels...
by David Welling
You need H2 buffers when you have a short DI barrel to slow down the BCG. Good stuff!
