recently acquired an SFAR in 308. first issue for me was chewing up the brass heads pretty bad.
I calmed that problem down a great deal by installing a tubs flat wire spring and going to the heaviest buffer. I accomplished this by installing three tungsten weights. that made a lot of difference..

on the recommended two setting the gun is somewhat over gasped ejecting at about the 230 position. you change the number three it moves up to probably about the 2:00 position.

my next step is I will install a superlative gas block. all the reading and research I've done says that will fix that over gas issue while still providing plenty of setting to use for suppressor if so desired..
