Have any of you ever had a rifle that short cycled with marginal ammo and ran great with some HXP? A little diddy that Stu discovered was to simply back out the gas lock screw one turn thus creating a larger front chamber in the gas cyclinder. I noticed this thread on the CMP today http://forums.thecmp.org/showthread.php?t=43109&page=3
Stu told me about this little trick about three months ago while he was at the range. I've tried it on many shortcycling rifles that customers have sent me and it has worked to make them cycle in all but one case. That rifle had an oprod spring which was 2" to long????
This makes me believe that Erics gas lock screw with the larger front end will do what he says it will do. It would probably also make a rifle that otherwise shortcycles, now cycle.
