Thanks to continual product development the new i-model SL suppressors are lighter than their predecessors, but just as effective. They are assembled from precision cast components made of 300 series stainless steel by welding. The surface of the suppressors is extremely durable CeraKote.

The AU MP5 suppressor is a lightweight, ultra-compact SMG suppressor designed for quick and easy fitting to the standard Heckler & Koch MP5 A-variant 3-lug muzzle.
Manufactured in Finland by Ase Utra OY, the AU MP5 suppressor incorporates Ase Utra's latest Si-series baffle technology.
The suppressor is an all-stainless steel, all-welded unit warranted for unlimited sustained automatic fire with either subsonic or supersonic 9x19 mm ammunition.
The suppressor does not change the weapon ballistics or muzzle velocity and does not require routine maintenance.
The AU "Easy Bayonet" MP5 Quick-Mount facilitates fitting and removal of the suppressor in seconds and incorporates a friction ring to prevent accidental loosening.
The suppressor is compatible with commonly-available forend and fore-grip weaponlight systems.
In addition to the reduction in sound signature, the suppressor substantially reduces recoil and eliminates muzzle flash.
