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.

Frequently asked questions

Which guns does this nozzle fit?

It is 20mm long to fit M16A1, XM177 and CAR15 series AEGs built to Tokyo Marui standards. Because nozzle length is platform-specific, always match it to your gun before fitting.

Does it fit standard M4 AEGs?

Many M4/M16 pattern AEGs share this TM-standard nozzle length, but always compare against your existing nozzle, as some brands vary. If unsure, measure the old part first.

What does the built-in seal do?

The internal rubber seal closes the gap between the nozzle and cylinder head, stopping the compression loss that occurs with a worn nozzle and improving shot consistency.

Will it raise my FPS?

It restores compression the gun is losing rather than adding power. Expect more consistent velocity, not an increase beyond what your spring is rated for.

Can Platoon Stores fit it?

Yes. Nozzle replacement is part of a routine service. See our airsoft gun repair service.
