NPAS for AEG
 

Finally. Although there are a lot of methods for variable fps on aegs, this one looks promising.

Neat idea but like hell im jamming a metal rod down my barrel just for an fps change like that.

if it works....kinda makes the quick swap spring by ares rather redundant

Just separate the upper and lower receiver. Something really easy to do before a game. Plus that way you can use a much shorter tool.

Seems to not be too consistent. I prefer my finely tuned aeg with it's set fps and 5 fps variants. rather than that accuracy crushing 20+ difference

inconsistent to say the least. not interested in the slightest!

so they built a louver into the piston to vent air. what sucks more is that you need to run a high power spring in it to start with to gain the top end. personally, I'd much rather swap springs, but then again, I just run different weapons indoors to outdoors. :)

+1 for inconsistency, I usually don't deliver any AEG to my clients that has over 4-6 fps variations, unless they don't want me to tune it up... 20+ fps variations means no accuracy at all...

That is a first gen product. I imagine that they will like all their products eventually make a more finely tuned version.
