Reviews & Ratings for Leupold BX-4 McKinley HD 10X42mm Roof Black — 1 review — Page 1

The Leupold McKinley BX-4 #119282 have become available this 4th quarter of 2014. It is an updated version of the original BX-4 McKinley #117790 that were revamped earlier this year. Leupold states the optics are the same, but changes incorporated are a more ergonomic armor coating, slimming down of the eyepieces and integrating a locked diopter adjustment in front of the focus wheel. These could be nice ergonomic advances, but did they achieve these improved results? Well, my new BX-4 10x42mm's are a mixed bag of Yes's and No's.

Pros:
*Eyepieces are nicely slimmed down.
*Armor Coating is not as thick as original BX-4's (#117790), yielding better ergonomic handling.
*Diopter adjustment dial is set in front of the focus dial, with a lock tab to maintain the setting...works well.
*Large focus dial is smooth and precise.
*Immersive 3D FOV depth.
*Accurate color renditions.
*Large interpupillary adjustment settings.
*Overall, they feel a little lighter and more compact than the bulkier original BX-4's.

Cons:
*Eyepieces have soft setting detents...need awareness for equal L\R adjustments. Found max adjustments not enough for my eyes to get an easy-on-the-eye FOV...needed to be deeper.
*Optical issues (to my eyes)! Overall, again (as in 117790's) I was unable to achieve a "Tack Sharp" focus compared to my beloved Leupold BX-3 Mohaves. Bright day light, afternoon shadows or dusk low light visibility (30 mins after sunset), the 119282's were better than I remember the 117...
