MGM Switchview™ Scope Throw Levers - the low profile throw lever popular with 3 gunners, and for good reason. The MGM Switchview™ lever requires a certain amount of clearance between the scope body and the nearest object for proper operation. If you have super low rings this may be an issue. Please measure carefully before ordering. The Switchview™ lever comes in flat black and is available for a variety of scope models.
The first four digits of the model number correspond to the diameter of the throw lever. For example, the 1290SV has a diameter of 1.290". If you aren't sure a throw lever is made specifically for your scope, you can measure the diameter of your throw ring and find the lever that will work with your scope. Usually you're looking for a lever diameter that's just a bit smaller than your scope ring diameter.
