Amazon : Tetra Gun Action Blaster Synthetic Safe, 10
Jul 15, 2018· Best and easiest gun cleaner I've used. Bonus is that is safe for the synthetic lower units common on mid-range guns. I use it every other time on the magazines also. Only problem that I have with Tetra products is quality control, or I would have gone 5 stars. The "straw" for accurate spray doesn't fit, and the copper solvent leaks all over.
