  • CNC Aluminium construction
  • 20mm/M-LOK hybrid with offset M-LOK slots
  • For M4/AR-15 AEG and GBBR Airsoft guns

If you're working on your SBR build, this handguard will be an asset! The HASTA Storm Free Float M-LOK Handguard is designed for any M4/AR-15 AEG or GBBR and requires an M4/AR-15 armourers' wench or a barrel nut tool to install. The Storm is constructed from CNC machined aluminium and finished in matt black anodisation, providing plenty of strength and flawlessly in-spec attachment interfaces. 

The Storm handguard replaces your existing handguard and barrel nut, offering M-LOK slots at 3, 6 and 9 o'clock with additional M-LOK slots at the offset angles, and a 20mm Picatinny rail up top which should mate with your receiver rail seamlessly. The offset M-LOK slots make the perfect spot to mount a tactical flashlight, keeping it tucked into the handguard for a slim, snag-free setup, ideally suited to short-barreled setups with limited accessory space. 

For a short-barrelled build, the Storm is the perfect handguard, marrying low weight, more M-LOK slots than its rivals and a menacing, angular profile which suits any modern platform!

Full description


The HASTA Storm handguard is the ideal choice for those building or upgrading a short-barreled M4/AR-15 platform. The handguard is constructed from CNC machined aluminium for precise, in spec accessory interfaces and reduced weight when compared to cast alloy alternatives, making this a fantastic upgrade for an AR that needs a bit more agility. 

The Storm Free Float is equipped with a 20mm Picatinny rail at the top, extending the receiver rail to permit larger optical sights and other mission essentials to be mounted along the centreline, reducing snag potential. M-LOK slots are also present at the 3, 6, and 9 o'clock positions, with additional slots at the offset angles, ready for any M-LOK accessories you choose to mount. 

7-inch handguards usually make mounting accessories a bit of a cramped affair, but thanks to the additional M-LOK slots at the offset angles, the Storm has plenty of extra options for where you can add your gucci kit. The offset angles are ideal for mounting a tactical flashlight, keeping it tight into the handguard for a more integral look. We recommend the WADSN M340A Scout Light Pro for this purpose as it includes an angle adjustable M-LOK mount, though other M-LOK mounted flashlights will do the trick. 

To install the Storm Free Float, you will need an M4/AR-15 Armourers' Wrench or a barrel nut tool. Included with the handguard is an aluminium barrel nut which shaves off a few grams when compared to a steel barrel nut but still provides ample strength for Airsoft purposes.

If your lil AR could use a style up, the HASTA Storm Free Float M-LOK handguard is a great way to do it. With a cutting-edge, angular look and more M-LOK slots than most will ever need, the Storm looks great and brings a wealth of functionality to back it up!
