Rock River Arms LAR-15M Operator DMR — 5.56x45mm NATO, 30+1, 16" Barrel, Black, BCM® SOPMOD Stock, 13" M-LOK® Handguard, Hogue® Beavertail Grip, Magpul® MBUS® Pro Sights, OEM Match Trigger (Model OP1510 | UPC 842834120536)

Precision meets practicality. The Rock River Arms LAR-15M Operator DMR is a duty-ready carbine tuned for Designated Marksman roles and serious range work. Chambered in 5.56x45mm NATO with a balanced 16" barrel, it runs fast and flat while delivering the accuracy, ergonomics, and repeatability you expect from a premium AR. A lightweight 13" free-float M-LOK® handguard, BCM® SOPMOD stock, Hogue® Beavertail grip, low-profile Magpul® MBUS® Pro steel sights, and an OEM match trigger come standard—so you can mount your glass and go straight to work.

Why the LAR-15M Operator DMR Stands Out

• DMR-Grade Accuracy: The free-floated 16" barrel and match trigger deliver clean breaks and tight groups, keeping impacts consistent as strings heat up.

• Billet-Level Ergonomics, Field Weight: The long 13" M-LOK® handguard gives you forward control, tripod/barricade versatility, and abundant real estate for lights, QD cups, bipods, and lasers—without influencing barrel harmonics.

• Premium Furniture:

  • BCM® SOPMOD Stock for a rock-solid cheek weld and minimal wobble.

  • Hogue® Beavertail Grip with palm-filling traction for confident trigger work in wet or gloved conditions.

• Steel Back-Up Sights: Magpul® MBUS® Pro sights are low-profile, rugged, and ready on day one—use them standalone or as insurance behind your optic.

• OEM Match Trigger: A crisp wall, glass-rod break, and short, positive reset help trim split times and call shots with confidence.

Built for the Modern Rifleman

• Fast, Repeatable Handling: The 16" system balances recoil control and maneuverability for vehicles, barricades, and tight structures.

• Optics-Ready: Flat-top receiver makes pairing with a LPVO (1-6x/1-8x/1-10x), red dot + magnifier, or mid-power scope simple.

• Mission-Flexible: From practical carbine matches to ranch patrol or training nights on the range, this DMR-tuned carbine adapts quickly to your role and loadout.

Real-World Advantages

• Stability in Every Position: The long, rigid handguard shines on tripods, bags, and rails, minimizing POI shift and aiding recoil tracking.

• Cleaner Breaks, Better Groups: The match trigger helps reduce sight wobble at the shot for smaller, more consistent groups.

• Maintenance Made Easy: Quality components and a free-float design simplify upkeep while protecting accuracy over time.

Ideal Use Cases (Where Lawful)

• Designated Marksman / Patrol Carbine: Enhanced precision with duty-capable ergonomics.

• Training & Competition: A natural fit for 2-Gun/Carbine matches and structured rifle classes.

• Ranch/Property Defense: Quick handling, dependable accuracy, and accessory versatility.

Setup Tips (Get the Most from OP1510)

1. Optic Choice: A 1-8x or 1-10x LPVO covers CQB to 500 yards; confirm torque on mounts and rings.

2. Zero Strategy: Many shooters prefer a 50/200-yard or 100-yard zero; verify cold-bore impact and confirm holds at 300–500.

3. Support Gear: Add a bipod at 6 o’clock and consider an Arca/M-LOK® adapter for tripod work; pack a small rear bag.

4. Ammo Vetting: Test 55–77gr loads to identify your barrel’s sweet spot; record velocity, SD/ES, and POI for a reliable dope card.
