Begadi PRO 70 Hopup Tensioner (3x5mm) - Standard barrel window

Begadi PRO HopUp Tensioner with a hardness of 70° and a D=3mm mount, suitable for many HopUp Units.

This tensioner is optimized for Begadi PRO HopUp Buckings/Rubbers,
but can also be used with many other buckings such as Maple Leaf.

The radius is 4.75mm (9.5mm diameter) and is therefore slightly smaller than the bucking itself. This causes the inner patch of the bucking to move down a bit more on the left and right sides, thus supporting the centering of the BB. Another feature are the outer bearing surfaces for the HopUp Lever, these are designed slightly slanted to distribute the pressure evenly.
