MP5 SD-Variants

 

THE MP5SD

The MP5SD is the full-time suppressed version of the MP5 submachine gun. This version uses an integral aluminum sound suppressor. Due to its ported barrel, it does not require use of subsonic ammunition for effective sound reduction like most conventional sound suppressed submachine guns.
The MP5SD is fully compatible with all existing MP5 accessories and trigger groups.
