Opinions Wanted: Barrel Choice for Suppressed SBR

[RicosRevenge]

Well, after a hiatus created by dumping the "what she don't know" fund on a Desert Tech SRS; I am back on track with the Grendel build.

Decided to go with a JP 18" vs an SBR and do an adjustable gas block to be able to tune for the suppressor. Should have it up and running as soon as the barrel, gas block and rail arrive next week.

Thanks for the help.
