LSR (sniper rifle)
The term LSR, commonly understood to stand for Long-Range Sniper Rifle, is a general designation rather than a specific model of firearm. It refers to any sniper rifle intended for use at extended ranges, typically exceeding 800 meters, and often chambered in calibers offering superior ballistic performance over intermediate cartridges like 7.62x51mm NATO.
LSRs are characterized by their high accuracy, powerful optics, and often, features designed to mitigate environmental factors affecting long-range shots, such as wind. Due to the specialized role and precision engineering, LSRs tend to be more expensive and require more specialized training than standard issue sniper rifles.
Common features associated with LSRs include:
- High-Power Optics: Scopes with significant magnification capabilities (10x or greater) are typical, allowing for precise target identification and engagement at extreme distances.
- Large Caliber Cartridges: Calibers such as .338 Lapua Magnum, .50 BMG (12.7x99mm NATO), and .408 CheyTac are commonly used for their flatter trajectories and increased energy retention at long ranges.
- Heavy Barrels: Heavy barrels contribute to accuracy by resisting barrel whip and maintaining consistent harmonics during firing.
- Adjustable Stocks: Adjustable stocks allow the sniper to customize the rifle's fit to their body and shooting position, improving comfort and stability.
- Bipods and Tripods: These provide stable shooting platforms, crucial for achieving accuracy at extreme ranges.
- Muzzle Brakes: Muzzle brakes reduce felt recoil, allowing for faster follow-up shots and improved shooter comfort.
The designation "LSR" is often used informally and may overlap with other sniper rifle classifications, depending on the specific military or law enforcement organization. It primarily emphasizes the rifle's long-range capabilities.
