Short Barrel Scope

The Short Barrel Scope is a Nerf barrel extension and scope that was released in August of 2017 under the N-Strike Modulus series.

It comes packaged with the Regulator and cannot be purchased separately.

Details
The Short Barrel Scope is a two-in one accessory that can be equipped to a blaster as a barrel extension or as a scope. It has an inverse tactical rail on the bottom and a tactical rail on the top. Even though it's supposed to be used as a scope only, its inverse tactical rail can be used to attach a blaster to another.

Like the Dual-Rail Barrel, the front muzzle part of the extension is compatible with other barrel extensions, allowing the blaster to have multiple extensions equipped onto it.

Trivia

 * Theoretically, an infinite number of Short Barrel Scope accessories could be attached to a blaster.
