Rifle Scopes Lens caps/covers NF SHV F1

I've used Vortex Defenders with great results.

The semi-universal Monstrum Tacticals my friend has are blatant copies of the Defenders at 1/2 the price and seem pretty good the few times I've flipped 'em. All you have to do it measure the diameter of your ocular and objective bells to know which size to use.
 
I used the NF Flip-up caps for the NXS 50mm off opticsplanet they work great if your willing to spend the cash.
