The Liberty 3 lug mount is made entirely of stainless steel for long life and durability. We designed this mount specifically for the H&K MP5 (9MM) family of guns. The surface of all parts is treated with a black nitride coating to provide excellent wear resistance as well as give the device a nice appearance. This device is backwards compatible with the original Mystic and the Infiniti as well. Adding just over an inch to the system this is also one of the shortest 3 lug mounts available. If needed, an adjustable spanner wrench can be used for disassembly and removal. These are available from MSC Industrial Supply Co. (Part #: 04570107) as well as many other retailers.

Please note that this mount is designed for pistol caliber carbine use or SUBSONIC rifle rounds only and may be damaged if used on full power (supersonic) rifle rounds, including failure of the mount and dynamic removal of the suppressor during use (read that as it may blow your can off the gun and fly downrange). You have been warned…

* Be sure to fully depress the mount and twist any time you are removing or mounting to the firearm.

NOTE: Some companies are making adapters that are not within the industry standard specs for this device. The internet is rife with prints that show numerous dimensions for the OD of the mount and this can cause loose motion issues when attaching a Liberty 3 lug device. We designed our mount to fit industry standard (which is the HK spec) and that spec is .5917″ +/-.0006″ for the barrel “nose” on the end of the 3 lug mount. As long as your barrel or adapter conforms to this information, you should not have any problem with mounting our 3 lug adapter to your firearm. Thank you, from the Liberty Team.

Note: A small amount of play is inherent to this design. This allows a smooth function when attaching / detaching. When the gun is fired with the can attached, the gasses will push the silencer forward adding alignment to the system.
