If you are trying to decide if buying an AR10 or AR15 rifle is the best decision for you, it is best to look at the differences between each rifle before making a decision.
After all, even the smallest difference can impact how happy you are with your purchase. Especially as each rifle feels quite different when held and when fired, and both have positives and negatives to using them.
The differences between the AR10 and the AR15 — While both rifles are extremely light and easy to carry, the number of rounds you can fire within a specific period of time is what generally separates one rifle from the other. The types of shooting they are useful for is also different with each one.
The AR10 tends to be a great rifle for big game hunters. This is due to it being able to use a larger caliber bullet, which allows each hit to carry more kinetic energy. That means each bullet has more chance of bringing a target to a complete halt than would a bullet from the AR15.
The AR15, on the other hand, is an excellent rifle for firing more bullets in a shorter period of time. It is also a good rifle for home security, for shooting smaller animals and for even controlling pests.
The AR15 also tends to be easier to aim and to shoot, and so is a good first rifle for you, your wife or even for a son or daughter.
If you are looking for a gun that can do just about anything you need it to do, the AR15 is often the better choice.
However, the AR10 is more accurate and more powerful than the AR15. Especially when shot at longer distances. This is particularly important if you are hunting more dangerous animals. Particularly as its follow-up action is fast enough that it can still bring down a charging animal if you miss your first shot.
The cost of an AR10 versus an AR15 — The AR15 tends to be the cheaper gun of the two (according to https://adventurefootstep.com/ar-10-vs-ar-15/), as well as one of the cheaper rifles currently on the market overall.
That is why, if cost is important to you, you may want to take a look at the AR15 first.
The ease of buying ammo — One thing gun buyers do not always take into consideration when buying a gun is how easy it will be to find the ammo they need to shoot it.
If this is a consideration for you, however, you may want to look closer at the AR15.
This is due to it being the most popular rifle in the world at the moment. That translates into easier access to ammo, as most gun stores stock it, as well as easier purchasing of gun parts, magazines and other accessories you may need.
