SDS Imports MAC-2 Magazine Extension +4 Rounds Black

The SDS Imports MAC-2 Magazine Extension is a drop-in tube extension purpose-built for the MAC-2 / MAC-1014 series of semi-auto shotguns and compatible variants such as the Spandau S2. Designed for straightforward installation using the host shotgun's existing magazine cap, this extension increases the 12 Gauge magazine tube capacity by +4 rounds with no permanent modification to the firearm.

Constructed with a durable black anodized finish for corrosion resistance and a clean factory-style appearance, the kit includes the extended magazine tube and a replacement spring calibrated for reliable feeding and cycling at the higher round count. It is a clean, reversible upgrade for shooters who want extra firepower from their MAC-pattern shotgun for sport, defensive, or extended range use.
