The Evolution of the S510 Platform

The Air Arms S510T Tactical merges the mechanical reliability of the world-famous S510 platform with the adaptability of a modern tactical chassis system. Rather than sitting inside a traditional hardwood stock, the S510 action is seated in an alloy housing engineered to accept AR-15 and M-LOK pattern accessories. This offers target shooters and pest controllers a modular platform that can be adjusted for body geometry, accessories, and shooting positions.

Series 7 Air Regulator & Lothar Walther Accuracy

At the heart of the S510T is Air Arms’ Series 7 regulator system. By maintaining a steady pressure level in the firing plenum regardless of total air cylinder capacity, the regulator removes the “power curve” inherent to non-regulated PCP rifles.

In .177 caliber, this regulated engine provides approximately 90 to 120 shots per fill with tight velocity consistency. Paired with a 395mm match-grade Lothar Walther barrel and fully shrouded silencer system, the S510T produces high accuracy downrange alongside low muzzle noise.

Modular AR/M-LOK Chassis Integration

• 3-Surface M-LOK Forend: The rigid aluminum forend features M-LOK mounting slots along the underside and both sides. This allows direct attachment of bipods, tactical lights, laser units, or sling swivels without bulky rail adapters.
• AR-15 Spec Compatibility: The rifle uses standard pistol grip and buffer tube mount locations. Shooters can replace the factory grip or buttstock with aftermarket AR-15 furniture
• Integrated Picatinny Optics Rail: Unlike older S510 models that featured traditional 11mm dovetails, the S510T incorporates a full-length 11mm Picatinny scope rail directly onto the top receiver, preventing scope ring creep under all shooting conditions.
• Ergonomic Side-Lever Action: The drop-down side lever cycles with light fingertip pressure, cocking the internal hammer assembly while indexing the 10-shot magazine smoothly into position.
• Expert PCP Maintenance Tip: When filling your S510T to its maximum 200 BAR limit, make sure to insert the filling connector fully into the quick-fill inlet and keep the dirt cap secured when not charging. Keep the side-lever linkage lightly lubricated with synthetic airgun grease, and apply a drop of silicone lubricant to the magazine rubber O-ring to maintain smooth indexing during rapid firing strings.
