Hey everyone,
I recently had the absolute privilege of speaking with Hannes Kepplinger, a former Steyr engineer and one of the developers behind the Steyr GB.
Since the GB’s gas-delayed blowback system (Barnitzke system) is notoriously specific about ammo, and keeping those gas ports clean is crucial for reliability, I had to ask him what he personally recommends running through it.
His answer was very clear: Magtech in either 115 grain or 124 grain (FMJ/FMC).
What ammo are you guys currently running in your GBs? Have you noticed a big difference between 115gr and 124gr in yours?
