Key Benefits
- Benefit 1: The first has to do
with the mount itself. The RPA configuration with the stepped ladder
certainly does work, but is incremented is rather coarse 5 minute
steps. It also leaves a small amount of light blockage along the
light-path when you switch to scope, even though the barrel of the
sight is removed.
The Riles front sight solves this problem by allowing you to remove the main part of the sight completely from the light-path of a scope, and reduces the coarseness of the RPA down to three minute increments. But with eyes like mine, the extremely fine flat-threads needed for elevation adjustments are damn hard to see, without strong reading glasses.
I decided to solve this problem by incorporating an "elevator wheel" running on a 3/8 -24 threaded rod, with four detents per revolution. one "click" on the elevator wheel provides one minute of elevation change with a sight radius of 36 inches. Running the wheel to the top of it's range and getting a good zero at 100 yards, allows you to just "count clicks" down to get to 600, 800, 900 and 1000 yards with almost no need to fiddle with the rear sight more than a half minute or so. Total range of adjustment is 35 minutes.
- Benefit 2: The second problem has to do with being able to see the target number boards, especially at 600 yards, without having to dip the muzzle of the rifle to read them. The only way to solve this is to use a front sight that has a clear visual through-put significantly greater than the 0.600 inches of clear view offered by the 22mm sight accessories presently available. Going to a full 30mm seemed to be a much better answer. The result I have provided in going this large is that the number boards are always visable.
- Benefit 3: The third issue is clarity of the sight aperture, and solid defination of the target bull. Make no mistake, this sight system is designed to solve the problem of "ageing eyes", by encorporating a larger diameter diopter (30mm), and using quality glare resistant lenses. For those of you who are not yet old enough to have this problem, you can stop reading right here. The key is ultimately the larger sight system's ability to gather more light and use it to build a clearer image of the target.
- Benefit 4: The sight mount has been altered to accommodate larger barrel tenon diameters. These include 0.812, 1.000, and 1.0625. The last two for use with various after-market bloop-tubes. An indexing ring for shared use of the front sight between barrels is now available. However, if you are replacing an RPA front sight, the indexing ring supplied with that front sight package, will still be usable. The "elevator arm" of the sight system is now dove-tailed to allow for greater "mating" surface area. To absolutely prevent upward creep from recoil, there are now two knurled clamp locks instead of the original one. The 22mm version of the Ross Precision front sight system now includes nylon-tipped set screws for the screw-in Gehmann / Anschutz accessories. If you have ever struggled with aligning the cross-bar of a variable front iris, you will appreciate this.
- Benefit 5: The sight system comes
with 5 apertures. These are sized in 0.25mm steps from 5-6mm.
