FX DRS MKII Tactical Standard Carbon Bottle 600mm Air Rifle

FX DRS MKII Tactical Standard Carbon Bottle Air Rifle

A Tactical PCP Air Rifle That Means Business

There are plenty of air rifles that look the part. Far fewer actually deliver where it counts — downrange, under pressure, session after session. The FX DRS MKII Tactical CB Standard is firmly in that latter category. Built by Swedish manufacturer FX Airguns, a brand with a well-earned reputation for engineering precision into every platform they produce, this rifle brings together a genuinely clever dual-reservoir layout, a fully adjustable regulated action and a barrel system that serious pellet and slug shooters will immediately appreciate.

Whether you’re punching paper at distance, competing in field target, or simply demanding the most from your equipment, this is a rifle that rewards investment with results.

Dual-Reservoir Design: More Shots, Better Balance

One of the most immediately practical features of the MKII Tactical CB Standard is its air management system. Rather than relying on a single underslung cylinder — a layout that adds bulk and shifts the balance — FX have integrated the primary reservoir around the barrel itself, then paired it with a secondary carbon bottle housed within the stock. The combined capacity reaches 740 cc, delivering a significantly higher shot count than a conventional DRS setup.

The carbon bottle keeps the overall profile lean and the handling naturally balanced. There’s no awkward protrusion beneath the forend to catch on equipment or restrict your shooting support, and the slim silhouette makes transport and storage far more straightforward. For field shooters and hunters especially, that slim, well-balanced feel pays dividends over a long day out.

Regulated, Consistent, Tunable

At the heart of the rifle’s performance sits the MKII AMP regulator — externally adjustable without any need to strip the action. This is a feature that experienced PCP shooters will understand the value of immediately. The ability to dial in regulator pressure at the range, adapting your setup to different pellet weights or slug profiles, is a genuine practical advantage rather than a marketing footnote.

Supporting the regulator is a 34 cc plenum, a notably generous capacity that smooths the delivery of regulated air to the valve system and helps maintain consistent shot energy across a full fill. Combined with the externally adjustable hammer spring — accessible once the stock is removed — the MKII Tactical CB Standard offers a depth of tuning flexibility that gives shooters real control over power output, efficiency and shot-to-shot consistency.

The Superior STX Barrel System

The Superior STX barrel system is one of FX’s flagship developments, and with good reason. The removable liner uses externally applied rifling to produce an unusually smooth internal bore surface. The practical result is reduced friction, improved projectile sealing and enhanced accuracy potential — qualities that matter whether you’re shooting premium wadcutter pellets or heavier slugs at extended range.

Crucially, the MKII system allows barrel liners to be swapped without depressurising the shrouded reservoir. For shooters who work across multiple calibres or regularly experiment with different liner specifications, this is a substantial convenience advantage.

Tactical Chassis and Handling

The aluminium handguard is purposefully designed rather than decorative. A full-length Weaver/Picatinny top rail runs the length of the forend, giving ample real estate for scopes, red dots or other optics. An integrated Arca-Swiss rail underneath supports tripods and shooting rests, while M-LOK slots along the sides and bottom allow you to build out the accessory setup that suits your shooting discipline. QD sling points complete a chassis that’s genuinely ready for field work.

A 30 MOA forward incline on the Weaver/Picatinny scope rail provides additional elevation correction for long-range shooting, extending the usable adjustment range of your chosen optic and making the platform genuinely viable for precision shooting at distance.

Trigger, Cocking and Practical Details

The fully adjustable trigger can be set for both stage weights, with additional adjustment available for blade height, reach and angle. For precision shooters, the ability to tailor the trigger to personal preference rather than simply accepting a factory setup makes a tangible difference to shot execution.

Cocking is handled via a smooth right-hand side lever — a system that allows fast, efficient cycling without breaking the shooting position. Filling is equally straightforward, with a fill probe port positioned on the right-hand side of the rifle for quick, convenient top-ups between strings.

Who Is This Rifle For?

The FX DRS MKII Tactical CB Standard is aimed squarely at the serious end of the market. It suits experienced PCP shooters looking for a platform they can tune and develop over time, as well as competition and field target shooters who need consistent regulated performance from a well-balanced, practical layout. The extensive calibre options — from .177 through to .30 FAC — make it a versatile platform across different applications and power levels.

If you want a rifle that performs well from day one and continues to reward as you develop your understanding of it, this is a compelling choice.

Built to Perform, Designed to Last

FX Airguns don’t do compromise, and the MKII Tactical CB Standard reflects that philosophy throughout. From the quality of the aluminium chassis to the precision of the STX barrel system, every element is engineered to contribute to a rifle that delivers on its promises — not just at first use, but across thousands of shots in the years ahead.
