Thread: Do you need an adjustable gas block when Suppressing an AR?

Hi there,
I want to suppress my Bushmaster AR15 16", ideally with a DPT over barrel unit.
But i understand if i have a stock gas block that i should limit my shooting to <60 rounds per hour...

I would like to stay with the factory front iron sight/gas block.

Is this really a problem, and what will the consequence be if i shoot more rounds, does to much gas get directed to the BCG?

Help, opinions please
...my next AR will have an adjustable gas block :p
Thanks Grant
