.308 Winchester – Proven Power and Versatility
The MD10 L is chambered in .308 Win, one of the most trusted rifle cartridges in the world:
Excellent choice for medium- to long-range shooting, hunting, and practical rifle applications
Delivers strong terminal performance and energy on target
Wide availability of both training ammo and premium match/hunting loads
Whether you’re punching steel, working a precision carbine course, or hunting (where legal), .308 Winchester gives this rifle real-world capability and authority.
16" Fluted Barrel – Compact, Efficient, and Accurate
The MD10 L .308 features a 16" fluted barrel, tuned for a balance of maneuverability and performance:
16-inch length keeps the rifle compact and easier to handle indoors, in vehicles, or in tight terrain
Fluted barrel profile reduces front-end weight and improves heat dissipation for more consistent performance during extended shooting
Maintains sufficient barrel length for solid velocity and accuracy from .308 loads
For shooters who want full-power .308 in a more agile platform, this 16" fluted configuration is ideal.
Black Cerakote Finish – Classic, Durable, and Low-Profile
The Black Cerakote finish gives the MD10 L a professional, understated look with serious durability:
Cerakote ceramic coating offers excellent protection against corrosion, abrasion, and harsh environmental conditions
Non-reflective black finish keeps things low-profile and tactical
Pairs seamlessly with the black Magpul furniture and components for a cohesive, purpose-built aesthetic
Whether you’re on the range, in the field, or training hard, the Black Cerakote keeps your rifle looking sharp and protected.
Free-Float M-LOK Handguard – Modular and Accurate
The MD10 L uses a free-float M-LOK handguard, designed for both performance and versatility:
M-LOK slots along the handguard allow mounting of:
Free-float design keeps the barrel free of contact, supporting more consistent point-of-impact and accuracy
Slim, ergonomic profile for a comfortable, secure support-hand grip
Configure the rifle as a DMR, general-purpose .308 carbine, or hunting rig—the M-LOK rail gives you the flexibility to do it all.
Magpul SL-K Stock – Compact, Lightweight, and Adjustable
At the rear, the MD10 L is outfitted with a Magpul SL-K stock:
Compact, minimalist carbine stock optimized for modern carbines, including .308 semi-autos
Adjustable length of pull to fit different shooters, body armor, and shooting positions
Slim, snag-resistant profile ideal for prone, barricade, and vehicle-based shooting
The SL-K helps keep the rifle nimble and easy to manage, while still giving a solid, repeatable shoulder weld for controlling .308 recoil.
Magpul MVG Vertical Grip – Confident Front-End Control
The rifle includes a Magpul MVG vertical grip, mounted to the M-LOK handguard:
Provides a firm reference point for the support hand
Helps manage muzzle rise and recoil, especially during rapid or multi-shot strings
Supports multiple modern grip techniques and shooting styles
On a .308 platform, control matters—and the MVG grip helps lock the front end in for better accuracy and faster follow-up shots.
Magpul MBUS Sights – Quality Backup Iron Sights Included
The MD10 L ships with Magpul MBUS flip-up sights, so the rifle is usable immediately:
Front and rear MBUS serve as high-quality backup irons or primary sights until you mount an optic
Spring-loaded, flip-up design for rapid deployment when needed
Durable polymer construction trusted by shooters worldwide
These sights make the rifle range-ready out of the box, and give you a reliable backup sighting system once you add glass.
Blackout Defense Flat Trigger – Precision Fire Control
A standout performance feature of this rifle is the Blackout Defense flat trigger:
Flat-faced design promotes a straighter, more consistent trigger press
Crisp break and short, tactile reset for enhanced accuracy and faster follow-up shots
Significant upgrade over standard mil-spec triggers, especially for precision and practical rifle use
If you care about tight groups and responsiveness, this trigger helps unlock the full potential of the MD10 L platform.
20+1 Capacity – Serious Firepower in a Compact .308
With a 20+1 round capacity, the MD10 L offers plenty of ammunition on tap:
Ideal for training, tactical-style drills, and extended range sessions
Reduces reload interruptions during practical courses or competitions
Works with quality AR-10–pattern magazines (where lawful and appropriate)
In a .308 semi-auto, 20+1 rounds means you’re well-prepared for demanding shooting days and scenarios.
Magpul Furniture – Rugged, Comfortable, and Proven
The MD10 L features Magpul furniture, known for reliability and shooter-friendly ergonomics:
Magpul SL-K stock and MVG grip provide durable, comfortable contact points
Designed to withstand real-world abuse while maintaining performance
Clean, modern profile that complements the rifle’s tactical look
