LocoToro 2 Posted January 17, 2012 Report Share Posted January 17, 2012 I use the 5.45 x 39 military surplus ammo (sardine can). I usually go through 500+ rounds per session. I notice that I get an orange/ rust color residue specs on the piston. What is that s**t? I clean my guns after each use, using Hopps 9 solvent and lube. I was recently told that Hopps is not effective on corrosive ammo. What's a good solvent to use to nutralize corrosive residue? Also, I heard that the gas tube dosen't need to be cleaned, that it burns off? I scrub the hell out of mine with a 12 ga bore brush and it takes a while to get all that gunk out. Is there a better technique? Quote Link to post Share on other sites
