The Unity Tactical Monkey Bar is on sale for $34.95 for a limited time. If you have an MBUS Pro Front Sight, this may be just what you need.
The Monkey Bar is a drop-in replacement for the small steel rail clamp on the MBUS Pro Front Sight. It serves two purposes: to hold the MBUS Pro to the rail and to provide a mounting interface for any of the Unity Tactical’s Fusion accessories like rails and flashlight rings. Additionally, it will accept Surefire’s M300/M600 Scout Lights without the need for an adapter. It is a very compact and very light weight way to add a light to your carbine that is equipped with an MBUS Pro Front Sight.
