Im using standard Carbine buffer and spring which came supplied with my collapsable stock. The 6.5 Grendel 20 inch barrels are generally smooth shooters and if you own the standard carbine buffer Id try it first. I have a T2 and H2 buffer but have only used them on carbine gas 6.5 Grendel but I dont use suppressors.
