Key Features

• Salt-Bath Coated Bolt Carrier Group — Why it matters: This treatment offers superior corrosion resistance and smoother cycling over traditional phosphate finishes, reducing friction and extending service life in adverse conditions.
• 15-Inch Slim M-LOK Handguard — Why it matters: The continuous top rail and M-LOK slots let you mount lights, lasers, and grips exactly where you need them without extra weight, keeping the rifle balanced and nimble.
• Forged 7075-T6 Aluminum Receivers — Why it matters: Forged construction provides greater strength and structural integrity than billet or cast alternatives, ensuring the rifle holds zero and withstands heavy use.
• 6-Position MFT Minimalist Stock — Why it matters: Adjustable length of pull accommodates shooters of different sizes and layered gear, while the minimalist design sheds ounces without sacrificing cheek weld or lockup.
• Spec15 Oversized Tac-Latch Charging Handle — Why it matters: The enlarged latch allows easy manipulation with gloved hands or under stress, reducing fumbling during critical moments.

Who It’s For

This rifle suits the traditional shooter who values proven direct-impingement reliability and quality materials over gimmicks. It’s a solid choice for range work, duty carry, or training courses where you need a rifle that runs hard and stays accurate. The stainless barrel and salt-bath coating appeal to those who shoot frequently and maintain their own gear.

Pros & Cons

• Pro: Salt-bath BCG reduces carbon fouling and cleaning time.
• Pro: Forged receivers offer long-term durability and resale value.
• Con: Non-adjustable gas block means limited tuning for suppressed use or different loads—plan to swap if you run a can regularly.
