Please choose from one of the preset sizes or to order a custom sized lens protector select "custom: message size required" and send a message or add a note during checkout with the measurements.

Best measured with calipers, but a ruler can work too. Please send exact values.

A: Bezel diameter in mm. Measure the end of your sight/torch from side to side including the rim/body of the sight. 

B: Bezel height in mm. Measure from the rim of the sight/torch as far back as you would like it to fit. This determines how far onto your sight/torch the sight protector body will slide onto. Please note a postage surcharge may apply to bezel heights greater than 20mm. If your custom protector has B of greater than 20mm please also add a '2-3 day postage surcharge' to your order.

If you have any questions or need assistance with the measurements please just get in touch and I will be happy to help.
