new version river rock nightfire 2c?

[countybob]

just picked up a river rock 2c nightfire from my local target, after researching it i noticed in all the reviews i found it was a smooth body with grooves. the one i got has very nice knurling between the grooves and on the tail cap. all else seems to be the same, its not much for throw but the beam is smooooooth and clean. great for close to medium uses. it really lights up an area evenly. just wondered if this is a second gen or ???? the emiter is the same as the one in the reviews, the only difference seeems to be the knurling, making a great light even better.
