CZ Bren 2Ms 7.62x39 Stovepipes: Cause and possible solutions.
This video diagnoses frequent stovepipe malfunctions in the CZ Bren 2Ms chambered in 7.62x39mm. Analysis using high-speed cameras reveals the platform is significantly over-gassed, leading to excessive bolt carrier velocity and timing issues that trap spent casings. While modifying the gas plug can help, CZ is still investigating the root cause of this discrepancy compared to 5.56 variants.
