Another announcement from Systema Engineering as sent in by Kumi, and you can download the full PDF file here... "Due to the Gear structure within the Gear Box located in the Lower Receiver, it was conventionally impossible to achieve; however with our new system we are able to make the Ambidextrous Selector Lever a reality.

In the past we have received favorable responses from military enthusiasts in regards to the lever clicking sensation as well as the solid connection in modes; we diligently maintained in our new Safety Selector with the twist of it being on both sides of the receiver.

The foundation of this structure lies in the tough material used for both sides of the lever as well as the 3 gears that connect the levers together; which were designed for the gears to intertwine with precision leaving with no uneasy feeling.

In addition, for the Right Side Lever we created different designed changeable caps (sold separately), which allows the freedom to change the appearance of the design to suit your taste.

If you wish to place an order, please place the order as an option specifying for the Ambidextrous Safety when ordering the T.W. and/or the Challenge Kit.

For those who already have a T.W. we have this available as an upgrade kit.

The contents of the Kit are as follows:

A certain amount of experience and knowledge is necessary for installation; therefore please consult with the retailer that you purchased the kit for advice."
