KG-2 was originally developed to maintain the bore integrity of sniper rifles.
Unlike most other products KG-2 contains no ammonia and uses a mechanical method to
remove the worst of copper and lead build-up. In the most
cases KG-2 will perform exceptionally well in removing copper and lead with quality patches.
KG-2 does not need harsh brushes to help remove copper and lead build-up.
Nylon brushes are in fact recommended if a brush is needed.
Based on the theory of
removing the copper and lead from the lands and groves only while simply smoothing
over the impregnated copper and lead in the micro-fractures of the bore,
KG-2 will help reduce the need for fouling shots. This is the reason it is recommended
by SWAT and sniper teams. KG-2 is an ideal product for fire polishing
(A technique producing a finer finish than Fire Lapping).
For those shooters who prefer a chemical means to remove copper or for those times
the complete removal of copper is necessary please see the product description for
