The Icon Reborn – Sharper, Stronger, Smarter
Since its debut in 2015, the FX Impact has redefined what modern airguns can achieve. A true game-changer in both form and function, it quickly cemented its place as one of the most versatile, accurate, and innovative air rifles on the market. Now, with the release of the FX Impact M4, FX Airguns has pushed the platform even further—enhancing performance, rigidity, comfort, and control, all while maintaining the iconic aesthetics that shooters around the world know and trust.
What’s New in the Impact M4?
🔧 FX Quick Set Trigger (QST)
A revolutionary addition, the Quick Set Trigger allows instant adjustment between multiple trigger profiles—Hunter, Match, or Standard—all with a simple screw tweak. No upgrades, no swapping units. Just dial in your preference and shoot.
🧱 Improved Rigidity
The redesigned top plate is thicker and stronger, enhancing the structural integrity of the platform for a more solid, consistent shooting experience—especially noticeable under heavy use or competition stress.
✋ Refined Grip
The all-new FX Grip features a more sculpted palm swell, integrated beavertail, and a secure AR-style mount. It feels natural in the hand and offers improved ergonomics for both target shooting and field work.
💨 AMP Regulator with Brass Piston
Now fitted with a brass-piston AMP regulator, the M4 offers faster refresh rates, better consistency, and durability under higher fill pressures—rated to 170 BAR working pressure.
🔄 Redesigned Magazine
High-capacity magazines have been reengineered using stronger materials and a smoother rotating mechanism, ensuring reliable cycling even when loaded with heavier slugs.
🔭 Extended Optics Rail
The integrated dovetail and extended Picatinny scope rail give you ultimate flexibility for scope positioning, with perfect alignment and improved rigidity.
🎯 Design Touches
Small but meaningful refinements across the chassis—like functional cutouts, sleek lines, and improved access points—make the M4 as practical as it is good-looking. It’s evolution, not revolution—just as it should be.

Under the provisions of Sections 31 and 32 of the Violent Crime Reduction Act 2006, which were enacted through "The Violent Crime Reduction Act 2006 (Commencement No 3) Order 2007: firearms measures," specific regulations now apply to air weapons, their Pressure-Bearing component parts, and certain accessories.
Key Points to Note:
Restricted Items:
- Airguns: All airguns are classified as restricted items.
- Pressure-Bearing Parts of Airguns: This includes barrels, cylinders, reservoirs, and pistons.
- Functional Moderators (Silencers/Suppressors): Moderators that reduce the sound of discharge are also classified as restricted items.
Definition and Registration:
- Component Parts: While the VCRA does not explicitly define "component parts," the Home Office interprets this to include pressure-bearing parts such as barrels, cylinders, reservoirs, and pistons.
- Accessories: Only moderators (silencers) require registration by dealers.
Legal Requirements for Transfer:
- In-Person Transfer: It is an offence under the VCRA to transfer these restricted items through standard postal systems or to the end customer directly without the presence of both the buyer and either the seller or a representative of the seller.
- Representatives of the Seller: This can be:
- An employee of the seller who is a registered firearms dealer (RFD).
- Another RFD authorized by the seller.
- An employee of the authorized RFD.
Collection and Delivery Options:
- Collection from Store: Customers are encouraged to collect their restricted items directly from the store where purchased.
- Transfer to Another RFD: Items can be transferred to a local RFD for collection, though the receiving RFD may charge a fee for this service.
- Home Delivery: We offer home delivery through our in-house team to some areas of the UK. However, please note that this service has location restrictions and incurs higher costs due to the need for dedicated transport, making it more expensive than a standard RFD transfer.
