I am sorry, I do not have that measurement available.
It is difficult to answer. The Rem 700 LTR was drilled both for 6-48 screws and 8-40 screws at different times. You will need to check which yours takes. Both 6-48 and 8-40 screws are a standard thread pitch so a test screw should be easy to find. If your rifle takes 6-48 screws then this mount will work if it takes 8-40 screws you will need to get one of our HS Steel bases with 8-40 screws.
From the top of the receiver to the top of the rail the rear is .510 and the front is .395. For the 20 MOA version the rear is .547 the front is the same.
These come with the 6-48 screws. You will need the A146 or A135. These come with the 8-40's.
These come with the 6-48 screws.
The A292 or the A293 will both fit depending on whether you want 0MOA or 20MOA.
The NightForce Rem 700 1913 Mil-Std Base includes #6-48 X 1/4 Screws.
Yes, it will. It is still a Rem 700 action, just with some enhancements.
This is specifically for Remington 700.
