I bought 12 gram CO2 cartriges for my BYRNA air pistol by mistake. My model only takes the smaller 8 gram.


Looking to trade my full box of 12 g (10 count - 9 CO2 plus one oiler cartrige) for a box of 8 gram cartriges. Only OEM BYRNA - no aftermarket.


Or I will sell my box to ypu for $15 if you dont have 8 grams.


Thx
