We can all agree that AR’s are not only reliable but are great at short ranges from 0 to 300 yards.
But what if you want to reach out further to 400 yard or 1000 yards? For the larger cartridge would the AR be able to deliver the same punch as its cousin the .308 or 6.5 Creedmoor?
Before making the decision to go with an AR10 or AR15, lets take a look at the comparisons.
The AR10 rifle is an air-cooled lightweight rifle that is gas operated and comes with the 7.62mm (.308) barrel.
uses the standardized 7.62x51mm loads and has a standard 20-round detachable magazine box.
It weighs between 3.29kgs and 4.05kgs, without the magazine and ammo. The super-lightweight feature was as a result of the use of aluminum alloy.
The metal parts were save for the steel bolt, barrel and bolt carrier group.
With its direct gas impingement mechanism where the propellant gas goes through the rifle’s cylinder that runs parallel with the gun barrel thereby impinging the bolt carrier mechanism.
This produces a high cyclic fire rate of about 700 rounds per minute with a 2,772 FPS/ 845 m/s muzzle velocity.
This rifle employs the same “direct gas impingement” as the one used on AR10s.
Which results in 800 rounds per minute from this gun, with a muzzle velocity of 3200 FPS or 975 m/s being realized to a maximum effective range of about 600 yards.
Whereas the AR10 features the .308 Win or 7.62x51mm NATO chamber, the AR15 features the .223 or 5.65 x 45mm chambers.
In the AR10 platform, it is unsafe to load the .308 in a 7.62x51mm chamber but the .308 chamber can accept the 7.62x51mm loads. Similarly, you can load .223 cartridges in a 5.65 x 45 chamber of the AR15 but not the inverse.
For those using both AR’s, here are some parts that are commonly interchangeable between the two:
Who’s the Winner?
This is a question that is nearly impossible and hard to answer.
The reason is that these are both quality rifles that gives the users many advantages when using the AR platform.
So determining which one is the clear winner would definitely have to factor in how good the user is.
They both are lightweight rifles that used advance gas impingement systems to increase their rate of fire and muzzle velocity.
Each one also has a variety of ways in which they can be configure. This allows them to be tailored to meet each individual shooters needs.
As far as hunting big game goes the AR-10 most definitely would have the advantage over the AR-15.
In a wide open shot situation its extra length would not be much of a factor.
It also has greater one shot stopping power than the AR 15 does. Its heavier bullets can travel long distances fairly accurately too.
In a tactical situation the AR-15 definitely will give you the edge. AR15 is lighter and more maneuverable than its AR 10 predecessor.
It’s deadly accurate over shorter distances. The high rate of fire and increased muzzle velocity will also allow you to put many rounds into a target at a faster rate.
In short neither of these weapons has any major drawbacks that would prevent you from using them for hunting, target shooting or in a personal defense situation.
They both are accurate and rapid shooting weapons that are extremely deadly in the hands of a skilled shooter.
That is why there is no clear winner to be found between the two AR’s.
