Sorry
I'm reading my post, and i made a mistake..
I have Both in hand right now, and compare the extended Vs standard...
Now I remember why I've choose The extended.
It's the reverse of what I've wrote.
The Standard, Put the scope right in you're face, And, the rings are jam against the turrets.
The extended, place the scope about 1/2 further on the rifle.
Like i said, i have a Leupold, Long eye relief and my scope is in the most advance position,
To be perfect i need another 1/2..because I'm not in my natural shooting position, I have
to keep my head Standard on the ( rear ) of the stock.
Forgive my English..but i try to explain you in my word the facts..
If You wanna picture, of the Talley, just ask...! and i show you ...
