This is a civilian legal, factory registered, short barrel rifle (SBR). The SBR is civilian legal; however, because it is classified as a National Firearms Act (NFA) weapon, it requires registration with the BATFE.
The Rattler is a SIG MCX in a discrete platform. The Rattler features a 5.5" barrel with PDW upper, thin folding Aluminum stock and free floating M-LOK handguard. The Rattler is ready to go where-ever it's needed as the thin folding stock makes for easy concealment and stowage.
