>>870540I've an Eberlestock G4 that hasn't seen nearly enough abuse. Damned fine pack but it really needs a rifle or something to fill the rifle compartment; compression straps at the least. Anything to eat up the sway that the compartment creates whilst empty. That aside it has been as phenomenal as it was expensive.
Bungied side pockets are great for water bottles or canteens. The long, zippered side pockets accommodate my tripod and sighting scope without issue. I've MOLLE'd a tear-away IFAK to the belt for quick access but the face of the pack is more than adequate to strap an bulkier, full medkit for the qualified who wish to carry one. Between the belt, face and sides there is enough webbing to satisfy the most compulsive types who need an individual holster or bag for any given purpose. The central compartment is wide-open and accessible from either the top of the pack or via zipper on the front. Built-in, replaceable rain-cover is included and stows away at the bottom of the pack. Plus whoever it is that makes their 3L hydration bladder (I forget the name of the company at the moment) appeared extremely reputable based on the research I did prior to purchasing it (It is sold separately). Plus the gap between the two front-face compartments is a rifle-rest by design. During trips to the range I find it is the feature I enjoy the most.
All that aside I haven't bothered looking into Mystery Ranch, Kifaru or any of the other big name tac-pack producers so I might be missing out on something. I just know Eberlestock wasn't a total break-the-bank investment for myself and I've been pleased thus far.
