I have an ar pistol while I wait for my form 1 to come back. It has a phase 5 buffer tube. It is using a standard carbine spring with carbine buffer. My 5.56 upper and 300BO function well with it. I have a 762 specwar on the way. My question is should I get the spikes kit with ST-T2 buffer or just use the standard buffer. It currently cycles subs and supers fine but not sure if I'll need a heavier buffer for the suppressor. Anyone with experience please let me know.
