Zastava M90 OUT of GAS!
The Zastava M90 undergoes a rigorous 'Sand Tornado Test' with its adjustable gas block set to maximum. Initial testing reveals a failure to eject after about 10 rounds, attributed to sand ingress and a gas setting ring that jumped out of its locked position. The primary issue identified is the gas regulator retainer bracket's tendency to lose tension under recoil, requiring manual bending for a secure fit.
