Brand new in the box. If you're looking you probably already know this is one of the best pocket water filters on the market. Comes with a 20 year warranty.
Most places sell at around $380 (REI for one). Cheapest place i've seen is Amazon at $271. Will sell for $240. No pics right now but...
I was dead set on getting a 30 but I much prefer the gen 4 texture. After reading all the comments of the 30 being to big/bulky I really want the 30s, but sadly it's only made in gen 3 :( Guess i'll have to wait
Cheapest quality upper you'll find is probably going to be from PSA, but even then it won't be under $500 with charging handle and bolt carrier group. $600-$650 is doable.
