The FX Impact M4 is the latest version of FX's bullpup PCP, the platform that has won at the top level of airgun competition since 2015. The M4 brings the Quick Set trigger, which moves between hunter, standard and match feel with one screw, a thicker top plate for a stiffer chassis, a new UG1 grip and redesigned high-capacity magazines that handle heavy slugs.
In black, it's offered with 600 mm Standard, 700 mm Sniper and 800 mm Extended barrels, from .177 to .35. The AMP MKII brass-piston regulator works up to 170 bar from a 250 bar fill, and the 75 cc Power Plenum keeps shots consistent. The Sniper is 1000 mm long and weighs 3.25 kg.

Buying & Licensing
This is a Category A firearm (air rifle). You need a current firearms licence that covers Category A and an approved Permit to Acquire before we can release it. NSW buyers can collect from our Roseville Chase store. Interstate buyers can have it shipped to a licensed dealer of their choice, who completes the transfer under their own state's rules.
Frequently Asked Questions
What's the difference between Standard, Sniper and Extended?
They're the same rifle with 600, 700 and 800 mm barrels. Longer barrels add velocity potential and air capacity, at the cost of length and a little weight. The Sniper's 700 mm barrel is the popular middle ground for hunting.
Is a scope included?
No. Scope and rings are sold separately. The M4 has a 30 MOA Picatinny rail that slides along the top plate to set eye relief.
How do I fill it?
Fill to 250 bar from a dive bottle, hand pump or compressor using the supplied Foster quick-connector. Don't exceed the maximum pressure marked on the rifle.
What licence do I need?
A firearms licence that covers Category A, plus an approved Permit to Acquire for this rifle. See Buying & Licensing above.
