The NF is one of the better springers still out there. All the newer designs have the crappy Recon reverse-plunger...
Here's to hoping to revive the NF fame, haha.
The only problem is that with the nature of the design, I'd have to elongate the plunger itself, to compensate for the length of the weapon. It shouldn't be a problem though, as I'll probably lengthen it behind the trigger catch.
