Absolute, 100% agreement here.
Other 'beauties" include the K3, K2.5 and K1.5.... all of which I have, and have used with perfect satisfaction in the field.... down to thirty (or more) degrees below zero, and on HEAVY-recoiling rifles like the .416 Rigby and .404 Jeffery.
These sights are often available "used" on websites, and prices are generally reasonable.
