I used a very good rear sight for years. But this T2K rear sight incorporates several unique design features which make it more flexible and easier to use compared to its competition. It features several changes and improvements over current sights.
1. Longer mounting base. There are 6 hole options rather than the usual 5. (I always wanted my sight to move back farther for offhand).
2. Two mounting screws are supplied instead of one. This second screw can be used for getting the sight farther rearward for offhand without having to change to a different hole. It can also can double for a lost mounting screw.
3. Rounded click plate corners. All right-angle edges have been eliminated, making it easier to turn the knobs without dragging your finger against a right-angle corner.
4. Slightly larger knobs make it easier to see the numbers.
5. Larger knobs also allow two different sets of ball indents on each plate so the sight can be either a 12-click per revolution or a 6-click per revolution, using the same plate. Simply pick the one you want by changing the two ball bearing and spring positions on the knob. (You could have a 12-click elevation knob with a 6-click windage scale or vice-versa.)
6. Each knob has two tension screws to assure positive lockdown.
7. [OPTIONAL] 8-click/4-click per revolution plate allows tuning the desired amount of movement per click when using a rifle with a longer sight radius setup. Includes a corresponding windage scale. A sight radius spreadsheet is included with each sight to inform each user of exactly how far each click moves point of impact with 12/6 and 8/4 indent plates. I use 8-click plates with my 39-inch sight radiused across-the-course rifle and won't go back (this equates to slightly larger than a quarter minute per click -- 0.288 per click).
8. With the 12- and 8-click setup, the click plate divining mark is set slightly rearward in order to be seen more easily from position. The click plate must be rotated 180 degrees for the 6- and 4-click divining marks to align correctly.
9. The windage scale is set forward approximately 1 inch and angled so as to be more easily read while in position -- instead looking down to read the scale you look more forward (an extra inch of distance away from ones face makes it easier to read the scale). Divining marks at 12- and 6-o'clock make it easier to align the scale marks.
10. Both the windage and elevation feature steel bushings which eliminate oblonging of the guide holes from use with a heavy rear iris and/or sunshade. The steel bushings run the entire length of the aluminum block.
11. Windage has 30 minutes (12-click plate) of movement each direction from center position -- more than enough for a Palma® shooter.
