I dont KNOW that it is. But with two of my three scopes i cannot raise poi enuff. Still inches low. Anybody know what gives? I mean ya shouldnt have to go thru this scope ring some do some dont song and dance With an out of the box brand new gun?I love the Wildcat, super SWEET tigger but all this scopin ringin drivin me nuts! Ive tried high low and mid rings… shimming too, ive tried high rear, low front rings… got sdjustables otw but seriously? seems a pretty major design issue.
