The Sig Sig Sauer MCX Rattler CO2 BB Rifle reminds me a lot of the Umarex Steel Storm and Steel Force which are both Compact AR type Semi and Burt mode 4.5mm CO2 Blowback Airguns. Where the Sig Sauer MCX Rattler CO2 BB Rifle shines, is in the quality and realism as compared the Umarex counterparts. I do like that both the Umarex Steel Storm and Steel Force use dual 12 gram CO2 cartridges which I feel allows them to have more consistent velocity and performance as compared to the single CO2 in the Sig Sauer MCX Rattler CO2 BB Rifle. My First impressions without really testing the Sig Sauer MCX Rattler are all pretty positive but it will really come down to how well it performs and so I will put my recommendations on hold until I actually test it out!
