I'm building a suppressed 8" 300Blk rifle with a SLR adj. GB and will be shooting mainly subs. Which RE/spring/buffer combo will be the best option to run reliably and provide the smoothest/softest recoil impulse?
1) Standard carbine RE with a David Tubb's Lightweight flat wire buffer spring and H1/2/3 buffer
2) Standard carbine RE with JP Silent Captured Spring
3) A5 RE with either a Vltor/SprinCo green/or Tubb AR-10 flat wire buffer spring with A5H0/1/2 buffer
...or, will having an adjustable GB make the choices moot? Will a standard carbine spring and carbine buffer be just as good?
