Technical Point:
First Focal Plane Reticle First focal plane reticle stays valid at all power settings allowing you to fully utilize the specially designed reticle that shrinks or grows along with your target as you zoom in or out. The reticle offers quick target engagement at low power while offering precise holdover positions with finer details. For high-powered Ammunition(1200g/s)This scope is tested to rigorous standards----recoil tested to 1200G/s /3000 times. The scope can be used on the powerful rifle（0.223-0.30-0.308-0.338-0.50 bullets). Mil Clicks SystemWindage and elevation turrets with 0.1Mil clicks, providing an additional level of accuracy and ensures that the scope stays zeroed. Etched Glass Reticle Reticle etched on the glass that provides excellent backing support for complex reticle design and offers great durability and much higher shock resistance to recoil Fully Multicoated Fully Multicoated optics effectively reduces reflected light and increases the transmission of light giving you a brighter image than normal single coated lenses Illuminated Reticle The illuminated reticle provides greater visibility during dusk and dawn and other low ambient light environment. Physical hard Coating Physical hard Coating gives you an extra protection on the exterior lenses from dirt, oil and scratches or anything else mother nature can throw at you. 6061 T6 Aluminum The 6061T6 aircraft grade aluminum tube that has exceptional strength and superior mechanical integrity will protect these world class optics no matter what punishment you throw at it. Exposed Tactical Direct Dial Exposed Direct Dial Turrets for elevation and windage allow you to quickly make adjustment as you needed and engage your target within a blink of your eyes One Piece Tube Construction Heat treated one piece tube gives the scope extra strength over multi-piece tubes. A one piece tube also is better at keeping moisture out thus keeping your scope fog proof for the life of the product Waterproof Waterproof to protect the scope in the harshest weather conditions or if accidently submerged underwater Fog proof Fog proof to allow you to immediately engage your target when you take your rifle to cold ambient temperature from warm inside Shockproof Robust mechanical system with special designs on both control and erector system that give you the ultimate recoil resistance to withstand 1000G recoil for 1000 times. Nitrogen Purged Nitrogen Purging uses the inertia gas with bigger size molecules to purge any moisture out of the tube giving you better waterproofing and thermal stability .
What's new ?
The Coating:
In addition to conventional optical Antireflective and antireflective coatings, hard physical coatings are used on the outer surfaces of all lenses in the product, which is like wearing "armor" on glass to obtain scratch resistance.
Steel Turret Gear:
Most optical sight turrets has gear, and the accuracy of gears determines the accuracy of the sight. Usually the material of gears is mainly copper or aluminium, and even some high-end products are made of copper. Our 4-20X50 uses steel. After finishing all gears, quenching and hardening heat treatment is added. It's very wear-resistant and improves its life. In the optical sighting industry, steel gear is always a production problem. If the material is too soft, the hardness of the gear is not as good as copper, but if the hardness of steel is higher, the processing is very troublesome. After heat treatment, the size is prone to change. But we solved that.
Strong Metal Structure:
The main tube of the product has a shell thickness of up to 2.5 mm. It is well known that most of the ordinary optical sights are 1.8 mm, and a few are 2 mm. This optical sight is mainly used for powerful rifles, so the product is reinforced from inside to outside. It can ensure reliable use in harsh environment.
The Turret of SKWoptics riflescope uses big size gears.
Compared with the standard small diameter gear, the turret of SKWoptics optical sight reduces the total number of turning cycles on the premise that the total amount of adjustment is the same. In this way, the height of the turret is effectively reduced. The internal structure of the product is more compact and the failure rate is lower. As follows: SKWoptics 4-20X50 turret has only two adjustments, but it reaches 24 MIL (82.48 MOA) and 12 MIL (41.24 MOA) per turn. Ordinary optical sight turrets with small diameter usually rotate about 4-6 cycles to achieve such a total adjustment.
The Reticle Pattern
SS4-20x50FFP-MIL-B 's reticle on the first focal plane, based on mil radian ranging reticle. It can be used at any magnification
Rest zero
After zeroing in rifle:
1. Unscrew the top cap of the turret(windage or elevation), and pull it off of the turret. sit it aside.
2. Pull up the turret dial(you may remove it from the scope turret base if desired, but it is not necessary as long as you can freely rotate it ). Position it so that zero("0")on the turret's scale is lined up with the index mark on the scope. press down the turret until it locks in place.
3. Replce the top cap on the turret, rotation it clockwise until finger tight(do not over tighten). your scope is now zeroed.

What is FFP rifle scope:FFP is the abbreviation or abbreviation of "first focal plane" .Most modern variable powered riflescopes will have the reticle installed in one of two ways, in the first focal plane orthe second focal plane. Now, there are one or two manufacturers that have scopes with reticles in both focal planes but thisis more the exception than the rule. The focus of this article though will be the differences between FFP and SFP reticlesand what that means to the shooter.First Focal Plane:First focal plane optics are fairly common with many European manufacturers however that is no so much the casewith some American optics companies. It wasnrsquot until just recently that some of the larger names in the American opticsindustry began to offer scopes with first focal plane reticles. Part of the reason is that this method is costly and time consumingfrom a production and design stand point.First focal plane optics have the reticle installed towards the front of the erector or forward of the lenses that helpcontrol the magnification range of the scope. What this means is that as that scope goes through its magnification rangethe reticle will appear to change size, becoming thinner or thicker depending on the magnification. The reticle isnrsquot actuallychanging size but is in fact maintaining its size relative to the target image in the scope meaning that its subtensions staythe same. With the subtensions staying the same throughout the magnification range range estimation, trajectory compensation,and zeroing can be performed on any power greatly increasing the scopes utility.The rough diagram below shows reticle placement in a first focal plane optic. Note its forward position in the erector.
Below is an example of what the reticle would look like while looking through a FFP optic on high andthen low power. Eventhough the reticle appears to get smaller or thinner, it is in fact staying the samesize relative to the target.
