csmw 98 Posted November 15, 2010 Report Share Posted November 15, 2010 (edited) Put 500 rounds of low-brass Federal through a (NIB) freshly converted/polished S-12 (19"). NIB MDA drum. Cleaned out the gas-piston at 250 rounds and kept blasting. ZERO malfunctions. That is all Edited November 16, 2010 by C&S Metall-Werkes Quote Link to post Share on other sites
