The universal Kifaru worked well for me on a Seek pack across three seasons this year, albeit with a couple minor adjustments. I didn't like the way the universal lower cradle strap wrapped around my hip belt and dug into my hip, so I used a gatekeeper strap to attach it to the molle webbing on the hip belt, huge improvement. Second improvement was to use a carabiner, secured around load lifter strap, to secure the quick release higher on my right shoulder strap and keep it from sliding down , this kept the rifle snug into my body and much more out of my vision. I think my biggest suggestion for improvement on it would be to make the quick release strap red or orange instead of the same black as all my other straps, still it was intuitively the strap that I grabbed when needed.
