The SIG MCX Rattler vs. The SIG MCX Rattler Conversion Kit with Navy SEAL "Coch"
This video compares the SIG MCX Rattler 'full-up' pistol to a SIG MCX Rattler conversion kit mounted on an AR pistol lower. The conversion kit offers flexibility, allowing users to leverage existing AR pistol platforms and potentially ship directly to their door, bypassing FFL transfer for the upper receiver. The full Rattler requires FFL transfer as it's a complete firearm. Both platforms feature 5-inch barrels and are discussed in terms of caliber interchangeability, cost, and shooting characteristics.
