Sticks - have a good friend way up north who had a problem with his MSR short-strocking - no matter what! Worked fine by hand but just would not cycle properly when fired. We looked at / discussed many things and he finally sent it off to an upstate "wizard". Turned out that the inside of the carrier was not machined properly and the gas rings were hitting and hanging and accelerating the bolt travel time. Replaced the carrier and all went well. - Just a thought.
