IMHO, Bushnell Elites are highly underrated.
4200 series are rated at 95% light transmission, while the 3200s are a tad less, roughly about 91% to 92%. Not a big difference that most would actually be able to detect.
95% transmission is, scientifically speaking, about as good as it possibly gets for variable scopes...regardless of marketing claims.
I read recently that Wholesale Sports has a sale on the 3200 3x9x40s, less than $200. Might be worth checking out. For the money, probably doesn't get any better. Have owned a number of the Elite 3000 series scopes, no complaints!
If I recall correctly, Bushnell's endurance/shock testing involves 1000 rounds on a .375 Ouch & Ouch.
