Revival Defense Atlas-R Suppressor Adapter, Plan B Compatible

The Atlas-R is a 1.375×24, Bravo or “HUB” Compatible Suppressor Adapter we designed to accept the RF line and other Plan B Compatible Muzzle Devices.

The Atlas-R is a lightweight and low-profile suppressor adapter that utilizes the patent-pending Castle-Lock™ design, utilizing standard castle nut notches for ease of installation and removal using tools such as your common armorer’s or castle nut wrench.

The Castle-Lock™ System utilizes a combination of TDP Spec Castle Nut Notches along with four 1 5/16” wrench flats around the circumference give the end user the ability to apply accurate torque values during installation and the ability to utilize common tools for installation and removal. Underneath each wrench flat, we also incorporated a flat section before the chamfered edge to allow for a solid lockup when using a crescent or crowfoot wrench on the Atlas-R.

Finished in black nitride and proudly manufactured in the USA by Rearden Manufacturing.

    Picked this up for the polonium K i have in jail. Finish and machine work looks great. Spins onto my Liberty Precision muzzle devices flawlessly. Rooftop was fantastic as always.

    Solid Plan B HUB adapter alternative. Great fit and finish, I might switch over to this moving forward. I’d love to see a HT version and a Charlie version in the future.
