Although what's shown in the pictures seems to be a step up from a boresnake, practically speaking it's no different.
The question you need to be asking yourself is: Do you want to clean your precision rifle with a bore snake? I don't.
Boresnakes have their place in the precision rifle world as a field expedient method for clearing a fouled bore (talking unexpected contamination, not regular cleaning).
The company's cliche marketing is quite off-putting for me personally, but spending a short amount of time on their website I cant even figure out what's included in this "kit". So no, I would not recommend them for any of your guns. Not your rifles, not your shotguns, not your handguns.
If your seriously asking if this is a good product for your precision rifle, I would respectfully suggest you do some more research on cleaning your precision rifle and what tools, and methods you should utilize.
