Product Description

FX DRS MKII Tactical Standard AR15 Air Rifle

The FX DRS MKII Tactical Standard builds on the original DRS platform with a tactical chassis, expanded adjustability and the latest FX performance upgrades. Designed around the innovative Dual Reservoir System (DRS), it retains the slim profile of the original while adding an AR-style stock, modular accessory mounting and a range of user-adjustable features.

Tactical Chassis Design

Unlike traditional PCP rifles that use a bottle or air cylinder beneath the barrel, the DRS stores its 260cc air reservoir around the barrel shroud. This gives the rifle a slimmer overall profile and balanced handling while allowing the use of a lightweight aluminium chassis.

The Tactical Standard model features:

• Aluminium chassis
• AR-style adjustable buttstock fitted to a Mil-Spec buffer tube
• AR-compatible pistol grip
• M-LOK accessory slots
• QD sling attachment points
• Full-length Arca-Swiss rail for tripod compatibility

External AMP Regulator

The MKII is fitted with FX’s externally adjustable AMP regulator, allowing regulator pressure to be altered without disassembling the rifle. This makes it easier to optimise the rifle for different pellet or slug setups while maintaining consistent shot-to-shot performance.

Adjustable Hammer Spring

Hammer spring preload can be adjusted to fine-tune power output and air efficiency. Increasing preload allows the valve to remain open longer for higher power, while reducing preload can improve shot count and efficiency. Access to the adjustment requires removal of the buttstock.

Enlarged 34cc Plenum

The 34cc plenum provides a greater volume of regulated air behind the valve, supporting improved consistency and allowing the rifle to deliver higher power levels where applicable.

FX Superior STX Barrel System

The rifle uses the FX Superior STX interchangeable liner system. The rifling is formed externally, creating a smooth internal bore that reduces friction and supports excellent accuracy.

The removable liner system also allows liners to be changed or replaced without depressurising the air reservoir.

Fully Adjustable Trigger

The trigger offers extensive adjustment, including:

• First-stage travel
• Second-stage weight
• Trigger blade position
• Height
• Angle

This allows shooters to tailor the trigger to their individual preference.

30 MOA Scope Rail

A factory-fitted 30 MOA Picatinny scope rail provides additional elevation adjustment for optics, making it particularly useful when shooting at extended distances.

Side Lever Action

The right-hand side lever offers a short, smooth cocking stroke, while the fill port is positioned on the right-hand side for straightforward access.

Calibre Options

The FX DRS MKII Tactical Standard is available in:

• .177 – Sub-12 ft/lbs
• .22 – Sub-12 ft/lbs
• .22 FAC
• .25 FAC
• .30 FAC

Sub-12 ft/lbs models are suitable for UK shooters without a Firearm Certificate, while the FAC versions provide higher power where legally permitted.

Optional Slug Kit

For FAC models, FX also offers an optional slug kit and Super High Power plenum. These upgrades are designed to increase airflow and optimise the rifle for heavier slugs and higher power applications.

Who Is It Designed For?

The DRS MKII Tactical Standard is well suited to shooters who want a highly adjustable PCP platform. Its regulator, hammer spring and trigger adjustments allow the rifle to be tuned for different ammunition and shooting styles, while the integrated Arca rail and M-LOK compatibility make it equally suitable for tripod, benchrest or field use.

Summary

The FX DRS MKII Tactical Standard combines the compact Dual Reservoir System with a modern tactical chassis and the latest FX tuning features. With its externally adjustable regulator, enlarged plenum, Superior STX barrel system and extensive accessory compatibility, it offers a versatile platform for both target shooting and hunting, depending on the chosen calibre and power level.
