Looks like a MA5C.Maybe with a flash suppressor. Or a heavier barrel.
This, anyone who know's anything about guns would figure this out instantly.
Guns, generally speaking, are heavily modifiable. Barrels, firing mechanisms, clips, etc.
Saying, however, that the AR and the BR are the same, is like saying a D. Eagle and a 50Cal sniper are the same because they can use the same ammunition, as well as the 50 cal autofire (SAW maybe, I can't remember).
In other words(since my general knowledge is likely flawed)
There comes a time in customization or even evolution of a firearm when it earns a completely distinct classification, and ammo is not the only point that causes that distinction.
