NEMO OMEN Match 3.0 .300 Win Mag 22 inch 14rd

Description

The NEMO OMEN Match 3.0 .300 Win Mag 22 inch 14rd is a purpose-built AR-style precision rifle that delivers repeatable accuracy at extended ranges. Built around a 22-inch Bartlein-blank 416R stainless barrel and chambered in .300 Winchester Magnum, this rifle pairs a Geissele two-stage trigger with a Magpul PRS adjustable stock for stable, consistent follow-up shots. The tungsten Cerakote finish on NEMO billet receivers provides corrosion resistance and a low-glare field profile. Each rifle includes a 14-round NEMO polymer magazine, making it ready for precision competition or serious long-range work right out of the case.

Key Features

• Bartlein-blank 416R stainless barrel (22 inches) – Why it matters: Bartlein blanks are known for tight bore tolerances and consistent rifling, which translates to sub-MOA accuracy at 600+ yards with match-grade ammunition.
• Geissele two-stage trigger – Why it matters: A clean, predictable break reduces shooter-induced error during precision fire, allowing you to hold a tight group without trigger creep.
• Magpul PRS adjustable stock – Why it matters: Length of pull and cheek riser adjustments let you dial in a natural shooting position for prone, bench, or barricade work, improving recoil management and sight alignment.
• NEMO billet receivers with tungsten Cerakote – Why it matters: Billet construction offers a rigid, stress-free platform, while the Cerakote finish resists corrosion and scuffs in harsh field conditions.
• 14-round NEMO polymer magazine – Why it matters: A high-capacity magazine reduces reload frequency during competition or extended-range sessions, keeping you on target longer.

Who It’s For

This rifle is built for the precision shooter who demands consistent performance at distance. Whether you’re running PRS matches, hunting elk in open country, or fine-tuning loads for a 1,000-yard plate, the OMEN Match 3.0 gives you the platform to do it. It also suits the collector who appreciates quality components like a Bartlein barrel and Geissele trigger in a factory-built rifle.

Pros & Cons

• Pros: Sub-MOA accuracy out of the box; adjustable stock and trigger for a custom fit; durable Cerakote finish; high-capacity magazine included.
• Cons: Weight (around 11.5 lbs) is noticeable for carry in rough terrain; the .300 Win Mag chamber produces substantial recoil and muzzle blast, which may not suit new shooters.

Frequently Asked Questions

What is the effective range of the NEMO OMEN Match 3.0 in .300 Win Mag?

With a 22-inch Bartlein barrel and match-grade ammunition, this rifle is capable of consistent hits on man-sized targets out to 1,200+ yards. The .300 Win Mag round retains energy well past 1,000 yards, making it suitable for long-range competition and hunting.

Does the OMEN Match 3.0 come with a case or accessories?

The rifle ships with one 14-round NEMO polymer magazine and a basic owner’s manual. It does not include a hard case or optics. You’ll need to purchase a scope, rings, and a case separately.

Can I use standard AR-10 magazines with this rifle?

No. The OMEN Match 3.0 uses NEMO-specific polymer magazines designed for the .300 Win Mag cartridge. Standard SR-25 or DPMS-pattern magazines will not fit due to the longer action length.

Is the barrel threaded for a muzzle brake or suppressor?

Yes. The barrel is threaded 5/8×24 TPI, allowing you to attach a muzzle brake, suppressor, or flash hider. NEMO recommends using a heavy-duty brake to manage recoil.
