@Magnetom I wasn't familiar with the radio version, I looked it up. Sounds like the basic same ruck, but with a velcro flap for the antenna to stick out through. Do you think that would be useful for carrying a small rifle/carbine/shotgun inside? Certainly not a quick-draw situation, but might be OK for just carrying it to get somewhere. I once attached a machete case to one of mine, I kind of forgot about details on that.
