Christensen Arms CA101543157235 CA-10 DMR 5.56 NATO 20" 21-Round Carbine

The Christensen Arms CA-10 DMR 5.56 NATO 20" 21-Round Carbine is a precision-focused designated marksman rifle purpose-built for law enforcement, military, and civilian tactical operators who demand accuracy at extended ranges without sacrificing practical carbine ergonomics. This platform fills the critical gap between standard duty rifles and bolt-action precision guns, delivering consistent sub-MOA performance in a package that balances speed of fire with shot-to-shot repeatability. The CA-10 DMR addresses real-world engagement scenarios where rapid, accurate fire at 100–500 meters drives tactical decision-making.

Christensen Arms engineered this rifle around a free-floated, match-grade barrel that isolates ammunition performance from stock harmonics, eliminating vertical and horizontal stringing that degrades precision under rapid fire. The 20-inch barrel length optimizes velocity in 5.56 NATO while maintaining handling weight at 10 pounds—a critical consideration for operators conducting extended patrols or mounted operations. The 21-round magazine capacity provides substantial firepower while reducing reload frequency in sustained engagements, and the AR-platform ergonomics ensure intuitive manipulation familiar to military and law enforcement personnel. Christensen Arms' attention to receiver tolerancing and trigger quality translates to repeatability that rivals many bolt guns while maintaining semi-automatic rate of fire.

This carbine is ideally suited for precision riflemen in law enforcement tactical teams, military designated marksman roles, and competitive precision rifle shooters who prioritize accuracy over magazine capacity. The 5.56 NATO chambering provides logistical compatibility with standard military and duty ammunition supplies, simplifying training and deployment workflows. The AR-15 platform backbone ensures compatibility with industry-standard optics mounts, rails, and accessories, allowing shooters to configure the rifle for their specific mission requirements—whether that means mounting a 3–9x variable scope for medium-range work or a lower-power variable optic for dynamic team operations. Drop-in installation of Christensen Arms' matched components preserves accuracy while enabling field customization.
