Rated 5 out of 5 by from Great cap Same high quality as the eyepiece cap. Fits snug on my Crossfire 3x9-40. Doesn't rotate on the bell when flipping open. Opens/closes nicely after a couple cycles. Get eyepiece and objective.

Hi There, Your website lists the 0-40 as fitting the Razor HD LH 3x15 42, but a couple responses list that the 0-44 should be used. Can you confirm which is best? Objective-40 Fits: RAZOR® HD LH™ RZR-1589 RZR-1572 RZR-1565 RZR-1558 Thanks!

Asked by: LSU327
The O-44 fits the 3-15x42 Razor HD LH better than the O-40 fits, as the O-40 will be very tight.

I am interested in buying the defender flip cap. I have 2 scopes: Crossfire // 4-12x44 and a diamondback 4-12x40. Will the E 10 and O 40 work for both? Or do I need the O 44? Just want to check before I purchase. Thanks!
Asked by: Rob
E-10 / O-44 for the Crossfire and E-10/O-40 for the Diamondback and you should be good to go.
