Description.

There are rifles that blend into the background, and there are rifles that redefine the role they were built for. The Ares MSR303 belongs firmly in the latter category. Designed as part of the Striker series, this airsoft sniper rifle combines mechanical reliability with modern modularity, giving players a platform that adapts seamlessly to different skirmish environments. Built around the proven Striker system, the MSR303 is spring-powered, bolt-action, and engineered to deliver the kind of shot-to-shot consistency that long-range players demand.

The MSR303’s physical construction feels every bit as premium as its performance suggests. A CNC-machined 6063 aluminum receiver forms the backbone of the rifle, paired with a carbon-fiber outer barrel that reduces weight without compromising durability. This blend of strength and portability is a major advantage for players who need a dependable long gun but don’t want to lug around unnecessary mass. Out of the box, the rifle arrives housed in a custom-molded polymer carry case, making transport and storage as straightforward as the assembly process itself. 

Performance-wise, the Ares MSR303 doesn’t disappoint. Shooting between 400 and 425 FPS with 0.20g BBs, it sits perfectly in the sweet spot for a sniper platform: powerful enough to reach targets at extended distances, but within typical site limits for bolt-action rifles. The rifle’s adjustable hop-up system allows for fine control over trajectory, crucial when dialling in shots against distant opponents or battling inconsistent wind. Feeding from a steel-cased direct-feed magazine holding 45 rounds, the MSR303 avoids the rattle and misfeeds often associated with hi-cap style mags, making every pull of the bolt count.

Ergonomics are equally well thought out. The folding stock makes the rifle compact for transport or tight site navigation, yet unfolds into a full-length, stable shooting platform. Both the cheek rest and butt pad are adjustable, letting you tailor the rifle’s fit to your stance, optic height, or even body armor. The slip-resistant rubberized pistol grip adds comfort during long holds, while the fluted outer barrel provides a modern, purposeful look. When deployed fully, the rifle measures up to 1145mm in length, while folding down as short as 810mm for transport or CQB-style movement.

The full-length 20mm Picatinny top rail and modular handguard are designed with customization in mind. Whether you want to run a high-power scope for long-range engagements, a bipod for prone stability, or additional accessories like lasers and rangefinders, the MSR303 has the mounting real estate. The modular M-LOK slots add further adaptability without the bulk of quad rails. For players who enjoy building rifles around their preferred loadouts, this is a dream platform.

What sets the MSR303 apart from other sniper rifles in its class is its upgrade potential. ARES has designed this rifle to be compatible with the CPSB CO₂ power system, a drop-in upgrade that brings gas-like recoil and an FPS boost while retaining the rifle’s modular nature. This makes the MSR303 not just a sniper rifle, but a platform that can evolve with your playstyle. Some players prefer the simplicity and consistency of spring-power, while others chase the added immersion of recoil. With this rifle, you can experiment with both.

On the skirmish field, the MSR303 rewards deliberate play. Its bolt-action system means every shot is a conscious decision, but the consistency, accuracy, and power it delivers make those shots decisive. If you’re the kind of airsofter who prefers patience over volume, who thrives on controlling sight lines and punishing overexposed opponents, this rifle has been built with you in mind. And should you find it for less on another site, our price match guarantee means you won’t pay more than you should.
