Other than the obvious 3X magnification, what effect does the 3X lens have on the PVS-14? Does it increase the performance of the image, degrade the image, etc. How do they affect the light-gathering capabilities of the device (i.e. does it enhance or hinder the capabilities of an IR illuminator like the Surefire M952V). I've got a chance to pick-up a new Mil-Spec one cheap, but don't want to get something that I'm never gonna use. It'll be weapon-mounted, so weight won't be a concern.
Anybody have any experience? |
| The 3x is great to have. Any time you add magnification to a scope you take away some performance and light gathering ability. The Mil-spec 3x afocal has great glass and works very well. I use them all the time . It does take away some performance as all magnification but this effect is reduced by the good optics of the 3X afocal. |

Use them all the time. Glad you got or about to get the MS glass and it's LEAPS and bounds over the commercial glass, thus why they cost what they do. My experience is based on the latest Gen 3 PVS-14 intenser tube. I have found virtually NO light loss (how ever slight), resolution or clarity with only a slight case of vignetting of the edges while using a the Mil-Spec PVS-14 magnifier. As for enhancing any illuminators? You bet. While using a illuminator lets say at 300m+, you may see only the beam shinning out in the distance, but not really target recognition because you're viewing at 1x. Install the 3x MS magnifier and you can actually SEE your target. I have attached some pics below to show you some examples how good the glass on a 3x magnifier is. Older Pic of a PVS-14 MS 3x magnifier with a EO Tech 552 (When it worked  ) Real naked eye image though the tube was MUCH sharper than this.
These taken from our Supervision Review (I am still tired from that one!  )
1x PVS-14 - Targets at 500 yards 
3x MS Magnifier Attached 
1x PVS-14 - Man at 50 yards 
3x MS Magnifier Attached (Please note, image is NOT as clear as what was really seen. The point I wanted to make here is the slight vignetting seen here as well.) 
All in all, the Mil-Spec PVS-14 glass is superb IMHO.  Hope this helps.
