Extreme Outfitters has a sale (which I think has been going on forever) on acu granite gear packs. They both have a pretty funky frame sheet that allows different attachment points to adjust the placement of the straps. The Special Mission Patrol is a Pointman-ish sized pack, but the rear wall that zips open has what appears to be a padded laptop sleeve built in. Interesting, I guess. There are also molle loops on what appears to be the interior hydration sleeve, kind of a cool touch.
The Chief Patrol has a top loading bag, but the rear wall zips open. Unfortunately the lid is sewn on so you can't easily swap on a kifaru zxr lid. If's supposedly a little bigger than an ZXR, doesn't look it to me but I have just fooled around with it a little.
If you are looking for something with a good internal frame they seem like a good value if you don't mind ACU. I never had anything in ACU before, it seems, um, odd The ACU on these packs seems to have a lot of white.
The special mission patrol is less than a lot of simpler assault packs like the RAID and Eagle AIII. But, well, there is the color to deal with. The Chief Patrol looks to be a large Kifaru/MR quality ruck, but, again, there's the color...
The Chief Patrol will accept Alice bags ( or Malice bags or a MR Mountain ruck supposedly) and the instructions say you can order different size belts and shoulder straps.
i just noticed there are no compression straps on the smaller pack, that seems odd.
