**Concept** DIY Butlercreek mod (Adjustable Aperture with black out feature)

DIY Kit form to replace the front cover of your 09 & 09a Butler creek lens caps. 

The three sized holes will give enhanced close up focus & different levels of light input whilst the objective is still set to zoom at infinity. 

This is the initial concept design - we are using a friction hold system to stop the adjustment wheel from freely spinning and changing focus conditions whilst in use. 

As pictured is what is supplied - you will need to use your old pin & spring and fit to make a working aperture cover. As these are custom printed there may be some slight variations in in the manufacturing process so they may have some variations in the print from device to device. 

Recommended only for recreational use - for example like stargazing- airsoft/milsim and shooting/hunting.
