I bought this piece for a Bushnell Elite 3200 10x40mm I purchased from Opticsplanet. Because the Elite's housing turned out to be a hair under 40mm, a few relief cuts were needed to be made into the inner plastic snap ring to allow the plastic to bend and snap into the housing. After three small cuts, the shade fit in perfectly and even was easily capped by a Butler Creek scope cover. Despite the shade being listed for Leupold scopes, it should work for the majority of the 40m scopes out there.
Pros: Easily installed after slight modification.
