F2™ Nozzles

F2™ Nozzles

Regular price $25

There are currently 20 standard F2 nozzles available for installation into a wide range of replicas. These are numbered, rather than named, since the nozzle length can vary when the rifle is made by different manufacturers, even if it is the same model.

This can be from the manufacturer designing the rifle differently, or from the thickness of the gearbox shell affecting how far from the hop-up chamber the cylinder sits. Therefore one nozzle length may work in different rifle models but not necessarily work in the same model from a different manufacture. For example, a #6 nozzle works in an E&L AK as well as a King Arms FAL and ECHO1 M240, but does not work in a G&G, CYMA or TM AK which use a #2 nozzle.

We are using the make and model of the rifle which the nozzle length originated from in the nozzle description but this does not mean it is the only rifle it is compatible with.

If your gun is not listed in our Compatiblity Database a recommended nozzle length may calculated by measuring your original gearbox and applying the following formulas:

Centerline Nozzles: TIP = F + B - (A/2) + .293

A more precise measurement (which accounts for the hopup and bucking in use) may be obtained by installing a nozzle into the system which is slightly too long for the replica and measuring the nozzle setback when placed into the hopup.


The measured tip length should be within +/- 0.010" of an exiting nozzle to be compatible.
