I have a Full Stock 452. I mounted a tip-off rail, and QD rings from Warne hold a Leupold Ultralight 2.5x20 scope. This set up allows me to shoot with the aperture sight (i replaced the blade), and with the scope.
Excellent scope. Bright, sharp, long ER, easy to aim, quick on target. However, the heavy reticle is a bit too heavy for fine target shooting. I may send it back to Leupold to replace the reticle with something that still has heavy posts for but fine cross in the middle.
No problem shooting clays at 100, but at 50 yards a squirells' head is kind of hidden behind the heavy reticle.
However, this set up is really functional and good looking.
