To get accurate shots with your handgun, rifle, or shotgun, you will need to use an optical sighting device. However, you will be amazed by the numerous firearm optical accessories that you will come across when you walk into a gun store. To make the scope selection easier, here is a checklist that will prove handy at all times. 

First, you need to know about your shooting range before picking a BUIS scope. For a majority of firearm users, a 300 yard distance is considered long range, but that could be different for other persons. It is after you identify a range that it will be easy to pick a scope that complements it appropriately. 

Firearm scopes have various specifications, and it is essential that you understand what they mean. In all scopes, you will find some digits preceding the "X" and they simply mean the lens's magnification power. The digits indicate how many times the target is closer to you than its precise spot. Some numbers also are placed after the "X" and these are indicative of the diameter of the lens on the furthest end of the scope that is away from you. The bigger it is; the larger will be your field of view. 

Due to the possibility of hurting your eyes, especially when using heavy-recoiling guns, scope manufacturers now offer eye relief. It is the safe distance from your eyes to the scope that will also allow you to maintain target visibility and shooting accuracy. Visit this website at and know more! 

You need to select from a variety of rectiles because they are numerous varieties available. Some popular options include duplex, mildot, and bullet drop compensator BDC. The dots, lines, or a combination of the two that are marked on the scope to allow you mark your target are what gun professionals call rectiles. When choosing a rectile, give thought to the environmental conditions of the location of your shooting, your eyesight, and range. 

Give thought to parallax when picking a firearm scope. This feature allows the rectile to lock on a target even when the head moves slightly. It is most useful when the rectile and target focus are on a varying optical plane due to several factors. Such a situation can result in bad groupings or missed shots. 

A number of scopes will be coated to keep off glare from interfering with your target locking. The application of special coatings on lenses makes such features possible. There is a variation in the amount that a scope will transmit and its cost, and these are based on the number of coatings applied and their position. Popular options include coated, fully multi coated, multi-coated, and fully coated varieties. 


Your budget will determine the buis scope you purchase. In many cases, the price of a scope is based on repeatability, durability, increased adjustment precision, and optical clarity. To keep your spending at a desirable level; you need to ensure you only pick features that you will use in your shooting activities.
