FX Impact M4 Standard PCP, Copper, .177 (4.5 mm)

FX Impact M4 is the latest evolution of FX's popular all-round PCP air rifle, the Impact. With the M4, FX Airguns has refined its modular platform even further. This fourth generation brings clear improvements to both the internal components and the ergonomics, making it more precise, durable and versatile than the well-known M3.

AMP MKIII regulator & Power Plenum 750

The previous "Dual Regulator" system has been replaced by a single, very efficient AMP MKIII regulator with a brass piston. This new regulator is stronger, has a higher flow and is built to handle a working pressure of up to 170 bar. Together with the large 75 cc Power Plenum 750, it makes sure the rifle always has plenty of air behind the valve to deliver the right velocity – even when you shoot the heaviest slugs.

Newly developed Quick Set Trigger

The trigger mechanism on the M4 is completely new. With the new Quick Set Trigger, you can switch between two very different styles with a single screw:

• Hunting: A predictable trigger with a longer first stage.

• Sport: A feather-light match trigger with a very crisp break. The whole trigger unit can also be moved forwards and backwards, and the trigger blade can be adjusted for both height and rotation.

Extensive adjustment (Quick Tune System)

The FX Impact M4 is known for its adaptability. With the well-known Quick Tune System, you can adjust the hammer spring via a macro wheel (16 large steps) and fine-tune with the micro wheel. At the front you can adjust valve spring preload, and with the clever Dual Hole transfer port you can optimise the airflow for either regular pellets or slugs simply by rotating the barrel 180 degrees.

Features and benefits:

• Reinforced top plate: A thicker, stiffer top plate with a dovetail rail, where the supplied 30 MOA Picatinny rail can be placed exactly where you want it.

• Superior STX barrel: Uses FX's well-known liner system for minimal friction. The barrel can quickly be changed to other calibres or ammunition types.

• UG1 ergonomic grip: New AR15-style grip with defined contact surfaces for a secure hold on the rifle.

• Reversible cocking lever: The large, comfortable cocking lever can easily be moved from the right to the left side as you prefer.

• Adjustable butt pad: The butt pad can be adjusted steplessly for height to give the right shooting position for any shooter.

• Optimised rails: Fitted with Picatinny rails on the sides and underneath for quick mounting of a bipod and other accessories.

Technical specifications:

• Calibre: .177 (4.5 mm).

• System: PCP with AMP MKIII regulator.

Note: Check the air rifle regulations in your country, including age limits and licensing, before purchase. PCP equipment needs a high-pressure pump or scuba tank for filling.
