What to Look for in a Gun Cleaning Kit
It's really simple: You need to look for an even construction on any type of brush which may be included within any kit, and it goes without saying, brass insertion rods (certainly NOT steel!). Any swaging should be done in either a softer brass or aluminium.
Rotate the rods to see that the brushes move in a circular fashion and do not wobble. Wobbling indicates that either the brush heads or the rod/s themselves are not straight. Whilst this may seem like a big deal, it can make full insertion and removal from the barrel a big pain.
As the image below indicates, an even spiral brush construction should work the best with the capacity for the entire rod to able to rotate when either inserted or withdrawn from the barrel. As such there should be free movement of the main rod even when pressure is applied either during insertion or removal from the barrel. So look for good movement here.
The above brush (0.22 cal) is from Borekare. Not the evenness of the phosphor bronze wire spiral and that the brush construction is made from aluminium. Both of these materials are way softer than that of the barrel and thus will not cause any damage to your barrel. The image was taken at high magnification (X4 plus) and you can clearly see that only the tips of the wires are coated in barrel contaminating materials. Also note there is no distortion to the actual wires, this is important because these alloys must have good elasticity in order to last and tolerate many insertions and removals from the barrel.
