Flatland Shooter 22 Posted November 29, 2014 Report Share Posted November 29, 2014 Keep your mind out of the gutter, OK? Its been pointed out that hot loads tear up a MKA 1919. Mine is pre-XN. To those that have torn up their guns, what part(s) broke? Just the bolt? Extractor? Upper receiver? What? Will higher quality made in America replacement parts solve the problem? I don't plan on shooting a lot of hot loads but I am looking at shooting lots and lots of low power loads. I typically shoot 1-1/8 oz 1200 fps shells (over 2500 rds to date). But a friend borrowed my shotgun for a stage last weekend and used Win AA 1300 fps loads that seemed to cycle significantly faster that my loads. For matches I might go with a little hotter load but I also want to make sure this gun stays in good shape and match ready. Information would be appreciated.

SHOTGUN MESIAH 855 Posted November 30, 2014 Report Share Posted November 30, 2014 Bolt and drive block seem to be the main things that fracture. The polymer feed ramp gets chewed up pretty good, but usually by user error on that. Quote Link to post Share on other sites
