Questions & Answers
What size is the turret caps? The replacements are discontinued and it didn't specify which others could be used. Expert Answer

Unfortunately, we do not currently carry replacement caps for this riflescope. I would recommend contacting Vortex directly for assistance in sourcing a replacement set.

Will the mount fit my Winchester 3030 Expert Answer

The Vortex Diamondback 4-12x40mm Riflescope does not include any scope rings. You will need to use a 1-piece base or a picatinny rail base with a set of picatinny rings to mount this scope. Email us at Techsales@opticsplanet.com for assistance.

A lot of value for the price. Great glass in this scope. Can’t really tell a clarity difference between the 4x all the way to the 12x. Plus vortex lifetime warranty. Use vortex on most of my hunting rifles and have never had an issue.
