SR-25 and m4/m14 Air Nozzle

Trivium01 · March 16th, 2008, 16:48

I recently discovered that if you break the stock air nozzle on an SR-25 (A CA25 in my case) the prometheus m4/m14 air nozzle makes a decent replacement. I took it to a local CQB arena and while they have the policy of not telling you what your exact FPS, I heard the chrono beep a few times (meaning it was shooting over 350FPS for a few odd rounds). I'm fairly sure that my gun is firing maybe 320-345 FPS with this nozzle, so it makes an easy replacement if your gun is broken with an op approaching. I'm still waiting on my proprietary CA25 replacement (been about 2 months).

If your gun is shooting 320-345fps with the stock spring, then it's shooting well below what it should be performing at. It should be closer to 380-390fps.

The standard M4/M16 nozzle is shorter than the SR25 one, hence, the lower velocity as air is escaping.

When I traded the gun it was reported as shooting at approximately 350 FPS, I suspect it has a weaker/bunk spring in it. I agree that air is most likely escaping, yet it makes a good substitution when you're in a pinch.

The CA25 in general has very poor air seals. The air seal nozzle is designed very poorly, and the piston head is absolute garbage. Air escapes all around it. The cylinder to cylinder head seal isn't great, either.

I've tested that spring in other platforms, and it should be hitting around 420fps in a properly sealed setup.

Swap the piston head to another aftermarket ventilated piston head and the air seal nozzle to the G&P version and you should get above 350fps.

I recently overhauled a CA25 and got it to 380-390fps.

The stock nozzle for them. They're really finnicky about other parts from what I can tell with my own G&P SR25.

alright, well i dont think the metal long one on my G&P SR is going to break anytime soon, i had just heard that the stock one doesnt seal very good.

I'm having a bit of trouble tracking down a G&P air nozzle for the SR-25 (As it turns out my supplier couldn't send my part and failed to inform me). Does anyone know offhand where I could find one? My google searches aren't turning up much.

Try contacting CA Directly. They're pretty good with stuff like this.

Other than that, I'm sure that the nozzle is the same as their M4/M16.

It's not the same.

Cool. I was just comparing pictures on the interflops, so I was making a mildly educated guess. Thanks for the correction

I guess I'd just stick with contacting Classic Army directly and see what they have to say.
