Correct nozzle for M16 pattern AEGs
The ASG Ultimate air nozzle for the M16A1, XM177 and CAR15 series is 20mm long to suit those platforms. Nozzle length sets how the nozzle meets the cylinder head and how it feeds the hop unit, so fitting the right length for your gun is essential to a clean air seal and reliable feeding.
Built-in rubber seal
A rubber seal built into the nozzle closes the joint with the cylinder head, protecting against the loss of compression that develops with a worn or unsealed nozzle. Keeping that air behind the BB gives steadier velocity and tighter shot-to-shot consistency.
Durable construction
The nozzle is made from reinforced plastic to withstand the repeated impacts of cycling. Like all ASG Ultimate nozzles it follows Tokyo Marui standards, so it fits TM-spec gearboxes without modification.
An easy performance win
Swapping a tired nozzle is one of the cheapest ways to recover lost compression and consistency. Combine it with a fresh cylinder head and piston head from our airsoft accessories range to renew the whole air seal.
