Cannot find any information on these, probably a special limited run, regardless got your pre-2018 improved Guide Light Frame The MR frames make it a breeze when carrying your excessively heavy loadout for a weekend MSW, another sparingly used bag that ended up in storage due to the unique factor of my collection, so many more that I cannot put up for sale but this one doesn’t have features my 6500 or Jump mountain ruck have. If you’re curious the MR Metcalf video from like 8 years ago is the same bag same features, same abilities, the overload shelf is probably the biggest hitter. You can place your overloaded plate carrier and helmet setups there plus food and water cans and leave your clothing and sleeping bag on the bag itself and you’ll be chilling Price shipped CONUS, BPF, shipping on weekends only, cannot make guarantees on item condition once it leaves my hands, sold as is. No offers. Will bundle with my other ads for a discount since shipping is expensive
