gunboy69 50 Posted February 5, 2012 Report Share Posted February 5, 2012 (edited) AR 5.7 Upper With 2 FN mags and brass catcher . The brass ejects straight down into the PMAG brass catcher. I have 150 rounds through it with no problems. As long as you have the supplied buffer installed it functons great. Ammo is just too expensive for me. $615.00 shipped or trade cross posted Edited February 5, 2012 by gunboy69 Link to post Share on other sites
