This video showcases the new MKO SD firearm from MK3 Firearms, featuring a collaboration with Dead Air and Ruger. The MKO SD utilizes the Dead Air RXD 22Ti suppressor, a 3D-printed titanium can designed to convert supersonic .22LR ammunition to subsonic. The firearm itself has a longer barrel than traditional MKO models to enhance stability and powder burn, with venting to release pressure, similar to an MP5 SD. The suppressor easily screws onto a modified muzzle device on the firearm.

Quick Summary

The Dead Air RXD 22Ti suppressor, featured on the MK3 MKO SD firearm, is a titanium can with 3D-printed baffles designed to convert supersonic .22LR ammunition to subsonic. The MKO SD's longer barrel and venting system enhance stability and pressure release for quieter, more stable shooting.

Frequently Asked Questions

What is the Dead Air RXD 22Ti suppressor and how does it work on the MKO SD?

The Dead Air RXD 22Ti is a .22LR titanium suppressor with 3D-printed baffles. It attaches to the MK3 MKO SD firearm via a dedicated adapter. Its design, combined with the MKO SD's longer barrel and venting, converts supersonic .22LR rounds into subsonic ammunition.

What are the key features of the MK3 Firearms MKO SD?

The MKO SD features a longer barrel than traditional MKO models for improved round stability and powder burn. It incorporates a venting system to convert supersonic .22LR to subsonic, similar to an MP5 SD, and comes with Acro mounts and Vortsson internals for enhanced performance.

How is the Dead Air RXD 22Ti suppressor installed on the MKO SD?

Installation involves screwing the suppressor's adapter onto the firearm's modified muzzle device. The Dead Air RXD 22Ti suppressor then screws directly onto this adapter, creating a secure attachment for effective sound suppression and subsonic conversion.

What is the advantage of the MKO SD's longer barrel and venting system?

The longer barrel on the MKO SD provides greater projectile stability at distance and allows for more complete powder burn. The venting system then releases excess pressure, effectively slowing supersonic .22LR rounds down to subsonic velocities for quieter shooting.
