I still use what I put together in Afghanistan and then keep refining it. It does what all the Eberlestock packs do, but without any of the extra shit, random pouches on the outside and weighs alot less. I had to figure this out on a requirement that I was able to have armor or a rack on which was for my primary weapon and everything secondary had to be on the ruck (or have the option to be moved to the ruck). Enough room for a radio, snivel gear, electronics, maintenance gear, hydration, all relevant data and landnav equipment, screening grenades, secondary IFAK and the ability to still scale it to stow NV equipment yet also not 'tied' to the rack/carrier.
- ATS Raid II ruck with internal pack frame with a 1000D dump pouch attached to the bottom molle that can roll up when not needed
- Outside zipped panel has precision ammo binder/loaded precision gun mags and data book/all shooting related information
- Left (weak side) lashings hold tripod against ruck
- Right side has IFAK and pouch for binoculars I can access with ruck still on
- 2x extra lashings (one high, one low) that horiuzontally go across the back of the ruck, yet do not go far enough to either side to interfer with any pouches or tripod; this is how you secure the rifle to the rear of your pack and have the buttstock sitting in the dump pouch. Simple secure with the 2 lashings and put a scope cover/muzzle cover on the rifle
- Unzip the ruck and it has an internal molle 'wall' in the pack; purpose build pouch for Trimble/data computer, purpose built pouch for PLRF15c and Kestrel, E&E type pouch with seperate compartments for batteries, essential maintenance tools, electrical tape, backup rifle parts, etc.
- Rear bag goes inside on the bottom
- Hydration flap is on the inside where the pack frame is and stays out of the way
With most of the equipment in it (not the rifle, tripod), it stills weighs less than most full sized gun carrier packs by themselves. Deploying the gun is 2x lashings (or more if you add another) once the pack is down, slide the rifle out, take the scope/muzzle cover off. Lay down in position and your data book/ammo is in the zipper pocket right there without even opening the pack. If you need your PLRF/kestrell/whatever, simply open the main zipper and its all right there on the molle 'wall'; no digging or getting 10 things out and making a yard sale around you.
