The Rail Blade is a Nerf-branded Perpetual Play Group foam weapon that was released in 2016 under the N-Strike Modulus series.

It comes packaged in the Close Combat Upgrade Kit and will be available for separate purchase at a later date.[1]


The Rail Blade is a tactical rail-mounted melee weapon, comparable to the Z.E.D. Squad Chainsaw. While it can be used as a standard melee weapon, its reverse tactical rail allows it to be attached to blasters as a melee weapon underneath the barrel, similarly to a bayonet. It also can be used as a handguard.
