Yet another Mystery box with good stuff inside for me to discover and checkout and share with everyone! In this Replica Airguns August 2025 Mystery Box Video I reviewed three products from Umarex, and all of them are some sort of BB gun related product, one pistol, one revolver and one rifle and interestingly not all are CO2, as one is AEG powered which is more or less a new thing with steel BB guns. Barra introduced their 400e AEG AR Steel BB Rifle a while back and now Umarex has their own version of a similar AEG BB rifle in a sightly more true AR platform called the Umarex AER16.

The Umarex Marlin CO2 BB Revolver is really just a Marline licensed version of their Marshal CO2 BB Revolver but it us $50 less so unless you really want the Marshal licensing then go for the newer Marline version. Another Umarex product out of this months Mystery Box was the Umarex DS11 1911 NBB CO2 BB Pistol which is a pretty basic almost all plastic NBB CO2 BB Tactical 1911 that uses the standard metal BB Stick magazines. It does however look a lot better than most of these simple NBB Plastic BB Pistols on the market so in terms of looks it has that going for it for sure.
