The RilesSight and Rightsight are 20tpi rack = .050"

so each notch equals 5 minutes English (0.010" per minute) or 6 minutes Australian (0.00833" per minute).

If your elevation records are in Australian minute, multiply 5/6 or .833 to arrive at correct elevation.

The recommended elevations on the foresight for RilesSights sold after 01 December 2010 are:

The recommended elevations on the foresight for RightSights sold before 01 November 2009 are:

notch 15 = 300 yards

notch 20 = 500 yards

notch 25 = 600 yards

notch 30 = 700 yards

notch 35 = 800 yards

notch 40 = 900 yards

notch 45 = 1000 yards

notch 45 = lowest possible position

If you have both models of RightSight, the manufacturer recommends you re-engrave the line on one ladder to make both identical.

Most 18mm and 22mm foresights are 1.250" centres whereas the Rightsight on notch 15/20 is 1.430" =.180" higher.

Therefore, your starting zero on notch 15 or 20 at 300 yards is ~ 18 minutes English higher on your rear sight

than your current 300 yard zero.

The final elevation on your rearsight will depend on:

sight radius,

bullet type,

powder load,

metric or imperial ranges

English or Australian minute rear sights.

Indexing of foresight lens (we suggest making small index line at 6 o'clock)

We recommend zeroing your rifle at 300 yards.

Then set the zero on the rear sight elevation scale plate

RilesSights: 30 verniers = 300 yards

RightSights: 20 verniers = 300 yards.

Then shoot all ranges to determine rear sight final elevations.
