Chambering & Capacity
This platform excels for those who demand maximum firepower in minimum space. The elimination of the buffer tube creates a genuinely compact weapon that remains fully modular. Whether for home defense, vehicle storage, or tactical applications, the Dissent MK4 delivers AR-15 capability in a package that defies conventional size limitations.
The 300 Blackout chambering pairs ideally with suppressed ammunition, making this an excellent choice for hearing-safe operation when equipped appropriately.
