AR15 Scopes are designed to fit Colts AR15 rifle design. As customizable as this rifle design is and with as many manufacturers as there are producing this type of rifle the choice of scopes for this design is equally diverse. Due to the importance of the choice of scope you eventually decide on for your rifle there are many things you should consider before you purchase a sighting system.
AR15 rifles are available in such a wide variety of configurations that it is nearly impossible to discuss them all. From high caliber high velocity rounds all the way down to the standard .22 long rifle round is available in the AR15 rifle. The choice of AR15 scopes will greatly depend on the type of ammunition you will be firing from your rifle.
Once you have decided on the caliber rifle you want you then will need to choose the configuration of that rifle. The variety of options range from the standard classic AR15 with the carry handle and smooth fore stock to a flat topped design with a rail system either on the top if the receiver or on the fore stock or even both if you wish. Your choice of AR15 scopes will depend on the type of configuration you choose.
After you have chosen the exact type of AR15 rifle you want you will then need to chose which of the AR15 scopes you would prefer. The choices can range from the usual high powered optical scopes found on many hunting rifles, compact red dot scopes or laser designator sights or even a combination of optics and laser sights.
How you plan on using your rifle can help in the decision making process for choosing a scope for your AR15. If you plan on longer range shooting then the optical AR15 scopes are probably the best choice as this type of shooting is what they were specifically designed for. If you plan on shorter range or more tactical situations then either the red dot or laser designator systems would be more suitable.
Tactical shooting requires more rapid target acquisition and greater ease of transition from one target to another. The easiest of AR15 scopes to use in this situation is the laser designator type sight. Essentially this sighting system puts a laser light dot on the place your rifle is pointed all you need to do it point the dot where you want the round to go and then pull the trigger. There is no need to even have the rifle tucked against your shoulder to use this type of sight. The red dot system works much more like a standard scope in that you would need to look into the sighting system to aim. Both the laser and the red dot system allow greater situational awareness for the shooter and quicker transition from one target to another.
Optical AR15 scopes are essentially standard scopes that are mounted to the rifle and require the shooter to look down the scope and line up the sights on the target to be effective. These scopes tend to take a little longer to use and do not allow as much situational awareness due to the concentration required to use them best. These scopes do allow a much better accuracy at longer ranges as they use magnification power of the optics to allow a clearer view of long distance targets.
There are some AR15 scopes that use both laser designators and optics these scopes allow a quick transition from short to longer range shooting allowing easy accuracy from between 5 to 500 yards. These are some of the newest and latest technology in rifle scopes and blend two sighting systems into one package.
However you plan on using your AR15 you will find many different choices in AR15 scopes from well known manufacturers. Along with all the different choices will come different price ranges allowing you greater choices when you go to buy your new rifle scope.
