The forward non-reciprocating side charger allows for quick bolt operation without coming off target. Direct impingement DISSENTS come equipped with a left side charger standard. Right side charging handles for DI models are available here. All DISSENT Upper groups include a lower receiver end plate and choice of adapter including: 1913 Picatinny rail buffer tube adapter or DISSENT folding stock.
