Hi guys. I'm looking to buy a scope flip up cover for the front objective on my Vortex Diamondback 3-12x40 HP scope. I've measured the front of the scopes objective and It's about 49mm from the centre and edge to edge. So my question Is guys, should I order a flip cover a size down or a size up? Or should I order the nearest measurement to 49mm?
The flip cover that I'm interested In buying Is the Butler Creek and these are a few of the options available before I purchase.
Cheers lads.
