Understanding the Rock River LAR-47's Appeal
The LAR-47's primary attraction lies in its ability to bridge the gap between the AR-15's familiar ergonomics and the 7.62x39mm's ballistics. This offers shooters several advantages:
- Powerful Cartridge: The 7.62x39mm round delivers significantly more stopping power than the standard 5.56 NATO round, making it suitable for hunting larger game or situations demanding greater terminal effectiveness.
- Affordable Ammunition: 7.62x39mm ammunition is generally less expensive than 5.56 NATO, making it a more budget-friendly option for range practice and bulk purchasing.
- Familiar AR-15 Platform: Shooters comfortable with the AR-15's controls and ergonomics can seamlessly transition to the LAR-47 without a steep learning curve. This is a significant advantage over other 7.62x39mm platforms.
- Magazine Compatibility: While it uses proprietary magazines, they are readily available and relatively inexpensive compared to some other less common calibers.
