RA-Tech Aluminum Nozzle NPAS Set for WE M4 Series Airsoft GBB Rifles

"This is a great upgrade for anybody looking to increase the longevity of their WE M4. This comes with the nozzle and the steel guides, both of which work great. I have not seen any of the drastic fps changes that others have for some reason. All in all it works like it should.

"I have had 3 of these in all my WE M4ís im which there is are some cons;
for example the fps does jump but that can fixed with a stiffer spring which will reduce it but not get rid of it.
Also the nozzle screw for the npas over time will loosen. I have fixed mine with loctite but you can with some teflon tape.
Now take note if you want to run your gun effieciently on gas in this nozzle adds 25g of weight which makes a difference in winter games!
But the pros are it will never break and will last forever!

"I have three of these nozzles and they do not mate up as well to the magazine rubber gas seal as the WE plastic nozzles. Best to buy 5 WE plastic nozzles for the price of one these and replace when they wear out. The good thing about these nozzles is that they will hold up better when using the CO2 magazines. Otherwise the plastic starts to wear and smell when rubbing against the rubber gas port on top of the CO2 magazine due to the very High fps generated by the CO2 gas mags.

"Complete Poop, this nozzle is horrible. I would not recommend one, I have tried all possibilities and none of them worked.
