Not to be confused with the Recon CS-6 barrel extension.

The Recon MKII barrel extension is a Nerf barrel extension that was released in spring of 2016 under the N-Strike Modulus series.

It comes packaged with the Recon MKII and the Recon CQ-12, and can be purchased separately on Amazon.


The Recon MKII barrel extension is a short barrel extension accessory. It has a set of front iron sights to help with aiming. The variant that comes packaged with the Recon MKII and Recon CQ-12 have a single tactical rail underneath; the variant purchasable off of Amazon strangely does not feature one. Unlike other barrel extensions, it does not have a bead at its attachment point, but rather a smaller locking system located on the attachment point itself, similar to the Proximity Barrel's locking system. This means that it will not lock on as well as other barrel extensions.

The rail has no connection point to snap in the attachments, making it more likely that accessories may fall off without force applied when equipping them.

Color schemes

The Recon MKII barrel extension has been released under the following color schemes:


  • The Recon MKII barrel extension is known as the MKII Barrel in the Customize Your Blaster online game.
  • The Recon MKII barrrel extension is listed simply as the Barrel Extension Upgrade on Amazon.
