LaRue LT-10

The LaRue LT-10 is LaRue Tactical’s precision 7.62 NATO / .308 Winchester rifle — based on the MRGG-S (Mid-Range Gas Gun – Sniper) platform LaRue developed for SOCOM evaluation. The LT-10 delivers serious mid-range precision capability with refinements that distinguish it from typical .308 AR-platform rifles: a tool-free handguard removal system, refined gas system tuning, and LaRue’s match-grade build standards. Available in multiple barrel-length configurations. Impact Guns carries the LaRue LT-10.

The MRGG-S Lineage

The LT-10 traces its design lineage to LaRue’s MRGG-S (Mid-Range Gas Gun – Sniper) project, which LaRue developed for SOCOM evaluation as a mid-range precision gas gun. That military development effort drove design refinements that distinguish the LT-10 from typical .308 ARs: gas system tuning optimized for accuracy and reliability with mid-range precision ammunition, barrel quality consistent with sniper-grade expectations, and component selection oriented toward duty precision rather than recreational shooting. The civilian LT-10 brings that engineering DNA to the consumer market.

Tool-Free Handguard Removal

One of the LT-10’s defining features is the tool-free handguard removal system — the handguard releases without removing the barrel nut or any tools, allowing field access to the barrel and gas system for cleaning, inspection, or barrel swaps. This is unusual at any price point and uniquely useful for serious shooters who maintain their rifles meticulously. The system allows handguard swaps between LaRue handguard configurations and barrel inspection without the typical AR-platform disassembly process.

Barrel-Length Configurations

The LT-10 ships in multiple barrel lengths to suit different use cases. The 14.5-inch configuration (with permanently attached muzzle device to meet 16-inch federal minimum) is the most compact, suited to mid-range work where carry handling matters. The 18-inch balances barrel length against velocity for 600-yard ethical hunting and mid-range precision. The 20-inch extracts maximum velocity from heavy .308 bullets and is the long-range choice. All configurations use LaRue’s match-grade barrels with appropriate twist rates for 168-175 grain match bullets.

7.62 NATO and .308 Winchester

The LT-10 chamber accepts both 7.62x51 NATO and commercial .308 Winchester ammunition. 7.62 NATO ammunition runs slightly higher pressure than commercial .308; quality rifles like the LT-10 are built for the higher pressure and shoot both safely. For shooters using mil-surplus NATO ammunition, the LT-10 is the appropriate platform; for commercial .308 only, any quality .308 AR works, but the LT-10’s mid-range precision design optimizes for match-grade .308 loads.

LT-10 vs. LT-15 vs. Siete

LaRue’s current rifle lineup spans three primary platforms. The LT-15 is the precision 5.56 NATO AR-15 for general use, training, and longer-range 5.56 work. The LT-10 is the 7.62 NATO precision rifle for mid-range work where .308 terminal performance matters — based on the SOCOM-evaluated MRGG-S platform. The Siete is the lightweight 7.62 NATO battle rifle optimized for carry weight rather than precision. Choose by caliber and use case: LT-15 for 5.56, LT-10 for serious 7.62 precision, Siete for 7.62 you carry.

What the LT-10 Is Built For

Mid-range precision shooting (300-800 yards) where 7.62 NATO terminal performance matters more than 5.56 efficiency. Hunters pursuing larger game where .308 ballistics make ethical shots possible at longer ranges than 5.56 supports. Tactical and law enforcement precision applications where the gas-gun platform allows faster follow-up shots than bolt-action precision rifles. Serious recreational long-range shooters who want a .308 AR built to genuine precision standards. The LT-10 is the answer when 5.56 isn’t enough cartridge and a bolt action isn’t enough rifle.

Frequently Asked Questions

What is the MRGG-S platform?
MRGG-S (Mid-Range Gas Gun – Sniper) is the precision gas-operated rifle platform LaRue developed for SOCOM evaluation. The military development effort drove design refinements — gas system tuning, barrel quality, component selection — that the civilian LT-10 inherits. The LT-10 is the consumer-market version of that engineering.

What accuracy should I expect from the LT-10?
The LT-10 is built to MRGG-S precision standards — sub-MOA accuracy with quality match ammunition is the design intent, with many rifles delivering tighter groups (0.5-0.75 MOA) with their preferred load. Practical accuracy with commercial .308 hunting ammunition is typically 1-1.5 MOA. The rifle’s mechanical potential is high; match ammunition is required to realize it.

LT-10 vs. Siete — which 7.62 LaRue should I buy?
The LT-10 for precision-focused use where accuracy and mid-range capability matter most — the rifle stays mounted on a sling or rest and weight is secondary to performance. The Siete for shooters who genuinely carry the rifle through field work where weight matters as much as performance. The LT-10 is the precision tool; the Siete is the field tool. Different priorities, different rifles.
