This is an attachment for my Macanudo Desert Eagle handgun, it comes in two sections: the Silencer and the handguard that attaches below that. The slide still cocks back smoothly, if not better because of the added rail support and the 8-round mag slides out too. The silencer is held onto the gun by rails below the barrel. This new attachment is a replica of a real silencer made just for this gun by the military. They had to make this new type of silencer because the power of the gun, recoil, and the speed of the bullet combined would shatter every other silencer they could put on it! This is actually still in development and is definitely illegal for the public to own!
