FX Impact M4 Extended — Power and Caliber Specifications

The Impact M4 Extended Copper delivers exceptional power across five calibers. The FX Impact M4 Extended price reflects premium Swedish engineering and the unmatched adjustability of the platform. Energy output reaches 117 joules in .22 caliber, 135 joules in .25, 169 joules in .30, and a staggering 211 joules in .35 caliber . The 580cc carbon fiber bottle fills to 250 bar (3,625 PSI) and provides up to 330 shots in .22, 160 shots in .25, 105 shots in .30, and 45 shots in .35 caliber . Magazine capacities are caliber-specific: 28 shots in .22, 25 shots in .25, 23 shots in .30, and 18 shots in .35 . Total length measures 1120mm, and weight sits at 3.35 kg .

AMP MKII Regulator and H.O.M.E. Power Plenum

The Impact M4 Extended features a completely revised regulator system. The AMP MKII regulator replaces the dual regulator system with a single, more powerful brass piston regulator . This new regulator offers stronger performance, faster refresh rates, and can withstand working pressures up to 170 bar. The H.O.M.E. (High Output Maximum Efficiency) power plenum increases power and efficiency while maintaining consistency at lower regulator pressures . The external power adjuster and the Quick Tune System with macro and micro-adjustment wheels allow for precise tuning in the field. The valve adjuster is nestled between the bottle and shroud, smoothly rotating to adjust power output .

Superior STX Barrel System and Magazine Redesign

The Impact M4 Extended features FX’s interchangeable barrel system for ultimate versatility. The 800mm Superior Heavy STX barrel is specifically designed for slugs and heavy pellets . The caliber change system allows you to switch calibers in minutes by swapping the barrel and magazine. The high-capacity magazine has been redesigned with stronger materials and an optimized internal mechanism that rotates smoothly even with the heaviest slugs . The magazine can accommodate projectiles up to 12.1mm in length . The 30 MOA Picatinny rail can be adjusted for perfect eye relief, and the sidelever cocking is reversible for left-handed shooters.

Quick Set Trigger and Real-World Performance

The Impact M4 introduces the all-new Quick Set Trigger, which is fully adjustable in every aspect . In testing, the trigger broke at 620g (20oz) in two-stage mode, with a crisp and predictable pull . Accuracy testing at 50m produced groups below 16mm with the .25 caliber version . One owner reports that his M4 is “a beast, sub 10mm groups at 25 yards” with no point of impact shift . Another owner achieved 175 shots before his first refill and was “smashing flies at 20 yards” . The rifle is exceptionally consistent, with one user reporting an extreme spread of just 7 FPS over a 10-shot string at 911 FPS .
