The only difference between the Picatinny rail and the Weaver rail is the size of the slots, although many rail-grabber-mounted accessories can be used on either type of rail.

Most scopes are mounted with two rings, one in the front half of the scope and one on the back half, which provides additional strength and support. The heaviest recoiling firearms, such as Thompson Center Arms Contender pistols in heavy recoiling calibers, will use three rings for maximum support of the scope.

Use of too few rings can result not only in the scope moving under recoil, but also excessive torque on the scope tube as the gun rolls up under recoil. Scopes on heavy recoiling firearms and spring piston airguns which have a heavy "reverse recoil" caused by the piston reaching the end of its travel suffer from a condition called scope creep, where the inertia of the scope holds it still as the firearm recoils under it.

Because of this, scope rings must be precisely fitted to the scope, and tightened very consistently to provide maximum hold without putting uneven stress on the body of the scope.

Rings that are out of round, misaligned in the bases, or tightened unevenly can warp or crush the body of the scope. Usually this results in the scope being offset to one side to the left for right-handed people, right for left-handed to allow the shell to clear the scope.

Alternately a scout rifle type mount can be used, which places a long eye relief scope forward of the action. A firearm may not always be able to fit all aiming optics solutions, so it is wise to have a preferred aiming optics solution first reviewed by a professional. Standard doctrine with iron sights is to focus the eye on the front sight and align it with the resulting blur of the target.

Gun users over 30 years of age with keen eyesight will find it harder to keep the target, front sight element and rear sight element well enough into focus for aiming purposes as human eyes gradually lose focusing flexibility with rising age. Telescopic sights allow the user to focus on both the crosshair and the target at the same time, as the lenses project the crosshair into the distance 50 m or yd for rimfire scopes, m or yd more for centerfire calibers.

This, combined with telescopic magnification, clarifies the target and makes the target stand out against the background. The main disadvantage of magnification is that the area to either side of the target is obscured by the tube of the sight.

The higher the magnification, the narrower the field of view in the sight, and the more area that is hidden. Rapid fire target shooters use reflex sights, which have no magnification; this gives them the best field of view while maintaining the single focal plane of a telescopic sight.

Telescopic sights are expensive, and require additional training to align. Sight alignment with telescopic sights is a matter of making the field of vision circular to minimize parallax error. LPS 4x6 TIP2 reticle, the bottom-left corner can be used to determine the distance from a cm tall target.

Dual combat sighting system: ZF 3x4 optical sight topped with red dot sight as used on German G36A1 assault rifles. Until the s, military use of telescopic sights was restricted to snipers because of the fragility and expense of optical components, though they had been used as early as the American Civil War on rifles, and even earlier for other jobs.

The glass lenses are prone to breakage, and environmental conditions such as condensation, precipitation, dirt, and mud obscure external lenses. The scope tube also adds significant bulk to the rifle. Snipers generally used moderate to high magnification scopes with special reticles that allow them to estimate range to the target. Telescopic sights provide some tactical disadvantages. Snipers rely on stealth and concealment to get close to their target.

A telescopic sight can hinder this because sunlight may reflect from the lens and a sniper raising his head to use a telescopic sight might reveal his position. The famous Finnish sniper Simo Hyh preferred to use iron sights rather than telescopic sights to present less of a target. Harsh climate can also cause problems for telescopic sights as they are less rugged than iron sights.

Many Finnish snipers in WWII used iron sights heavily because telescopic sights did not cope with very cold Finnish winters.

The market for military telescopic sights intended for military long-range shooting is highly competitive. Several high end optics manufacturers are constantly adapting and improving their telescopic sights to fulfill specific demands of military organizations. American companies that are also very active in this field are Nightforce, U. Typical options for military telescopic sights are reticle illumination for use under adverse light circumstances and the presentation of scope settings or ballistic relevant environmental measurements data to the operator through the sights ocular.

The former Warsaw Pact members produce military telescopic sights for their designated marksmen and developed a range finding reticle based on the height of an average human. The reticle used in the Romanian I. The target base has to be lined up on the horizontal line of the range-finding scale and the target top point has. The digit under which this line up occurs determines the distance to the target. The Israeli military began widespread use of telescopic sights by ordinary infantrymen to increase hit probability especially in dim light and extend effective range of standard issue infantry rifles.

Palestinian militants in the al Aqsa Intifada likewise found that adding an inexpensive scope to an AK increased its effectiveness. Today, several militaries issue telescopic sights to their infantry, usually compact, lowmagnification sights suitable for snap-shooting, like reflex sights.

American GIs in Iraq and Afghanistan frequently purchase their own combat optics and carry them from home. The Canadian Forces standard C7 rifle has a 3. The German Army G36 assault rifles have a more or less built in dual combat sighting system consisting of a ZF 3x4 telescopic sight combined with an unmagnified electronic red dot reflex sight. The dual combat sighting system weighs 30 gr 1 oz due to a housing made out of glass fibre reinforced polyamide.

All German G36 rifles are adapted to use the Hensoldt NSA 80 II third-generation night sight, which clamps into the G36 carry handle adapter in front of the optical sight housing and mates with the rifle's standard dual combat sighting system.

Within this tube is the reticule, which is usually etched onto a lens or-in some cases can be a wire filament. You also have the picture reversal apparatus, without which, your targets would look upside down.

The whole scope is then filled with nitrogen, so that it will not fog up on a cold day. Attached to the tube are the windage and elevation turrets and the scope will usually have adjustable parallax at either the objective lens end or mounted on the side. Parallax What is Parallax or, more importantly, what is Parallax error?

Well, to explain it is fairly simple. Hold your hand out in front of you and raise your index finger so it is pointing towards the ceiling. So, now move your finger back to the left so that it is covering up the target again and move your head back to its central position and your finger should now be to the left of the target. To compensate for this, most quality scopes have Parallax adjusters, which will enable you to set your scope with a parallax of 40 yards for a 40 yards target and no matter how much you move your head about, your cross hairs should remain on the target.

The problem is though that not all targets are at 40 yards, but can instead vary from say 8 to 45 yards and as you are not allowed to adjust your scope in HFT, you have to find a happy medium.

If you are going to hunt or shoot Hunter Field Target you will want a scope with a large depth of field. The way to check this is to take your scope and set the Parallax for about 25yards and place the magnification on 10x. Look at a target 45 yards away and adjust the Parallax until the 45yard image becomes slightly blurred. Then look closer and closer until the image becomes blurry again. If you want to shoot Field Target, then you will want a scope with 2 to 3 yards DOF, these types of scope have large objective lenses and high magnification and you use the parallax adjuster to dial in the range.
