gfl216 226 Posted December 8, 2015 Can anyone tell me what the (any number) X (another number) means? I know it has to do with the magnification and I believe the diamiter of what can be seen through the scope. Quote Share this post Link to post Share on other sites
Krdshrk 3,877 Posted December 8, 2015 Let's take a standard 3-9x40. 3-9 is the magnification, and 40 is the objective lens size (in mm)... The higher the number on the left, the higher the magnification. The higher the number on the right, the larger the lens. Quote Share this post Link to post Share on other sites
checko 180 Posted December 8, 2015 Magnification by (x) objective diameter Sent from my SM-G900V using Tapatalk Quote Share this post Link to post Share on other sites
gfl216 226 Posted December 8, 2015 So 3-9 means the magnification is 3 x the size of the target? Quote Share this post Link to post Share on other sites
voyager9 3,434 Posted December 8, 2015 So 3-9 means the magnification is 3 x the size of the target?Minimum magnification - max magnification. So in the above its a variable magnification scope that can go between 3 and 9 times magnification. Sent from my iPhone using Tapatalk Quote Share this post Link to post Share on other sites
NJGF 375 Posted December 8, 2015 If the spec only has 2 numbers as in 2 x 20 then the first is the fixed magnification while the second is the objective lens size. The bigger the objective lens generally the brighter the image. Quote Share this post Link to post Share on other sites
gfl216 226 Posted December 8, 2015 Ok, let me see if I have this right. The 1st number is the magnification, if there is 2 numbers the magnification is adjustible. The second number is the dimiater of the front lense and the bigger the lense the brighter the immage. Quote Share this post Link to post Share on other sites

First number is minimum magnification, "- plus second number " is maximum magnification, and number after "x" is objective lens size.

Krdshrk 3,877 Posted December 8, 2015 Primary Arms has the Lucid M-7 on sale right now. http://www.primaryarms.com/lucid-m7-micro-red-dot-sight/p/kt-l-m7/ Even Cheaper: Bushnell Trophy TRS-25 http://www.primaryarms.com/bushnell-trophy-trs-25-mounts-red-dot-sight/p/kt-bs731303/ Red dots aren't variable power - you can get a magnifier if you want zoom. Some Vortex red dots come with a "doubler" that you screw on for magnification... Quote Share this post Link to post Share on other sites
