Head to Head
AR-15 vs AR-10
The light, fast 5.56 platform vs. the bigger .308-class rifle.
AR-15 (5.56)
Best for: Defense, training, varmint
- Light and low-recoil
- Cheap, plentiful ammo & parts
- High capacity
- Easy for anyone to shoot well
VS
AR-10 (.308)
Best for: Big game & long range
- Far more energy downrange
- Better for large game
- Reaches farther with authority
- Heavier-hitting bullets
The Verdict
Pick the AR-15 for defense, training, and most uses. Step up to the AR-10 when you specifically need .308-class power for hunting or long-range work — at the cost of weight, recoil, and money.
