I am a self professed bag whore and have tried a shit ton of everything out there. Whether it be front or rear, the bag is a critical piece of your kit. I carry all of these in my rolling range rig
- Gamechanger by Reasor - I have seen the Armageddon one and they are nice but I bought this when it was made by Reasor and it is a fucking staple.
- Clutch by Reasor - No longer made and an example of a great idea marketed incorrectly. This was a pair of bags that could be linked together. Sold to be used as a system. Bad idea. Fact is they are two great bags used by themselves and very versatile. They are rectangular and wedge shaped units that are very heavy and stable.
- Precision Underground ELR - Great rear bag.
- Wiebad Pump Pillow - Shit tons of uses. I love using it as a firing arm support structure when seated using a tripod
- Traust - It is somewhat flimsy meaning not filled like others. However, when you need something squishy...it has no equal
I don't honestly think there is one or two that will fill all of your scenarios. However, there are probably a couple of bags that can solve 80% of everyone's use cases. I admit that I don't use all of the ones I carry equally
