CMMG Mk4 PDW (10/20)

Another option for a .300 Blackout PDW is the CMMG Mk4 PDW. This PDW is even smaller than the MPW with a barrel length of eight inches and an overall weight of just five and a half pounds. The Mk4 comes with a very lightweight RKm7 hand guard complete with KeyMod slots and a flattop upper. This makes it very easy for the operator to add light, lasers, and optics to the weapon as he or she sees fit. All of the furniture on the weapon is Magpul’s ergonomic MOE gear, including the adjustable butt stock, trigger guard, and pistol grip.
