[QUOTE="joegrizzy, post: 3649035, member: 45524"] sometimes with short barrels, the bullet will exit the barrel *before* enough gas builds up to reliably cycle the action. the gas will take the path of least resistance, and once that bullet exist, that's definitely the easiest path. so, since it's an ar, you've got a few options: you can tinker with the gas port (potentially drilling it out if the adjustable block doesn't cure the issue), you can tinker with the buffer (altering weights), you can tinker with the BCG by possibly going to a lighter weight material. if you had a can lying around you could test this theory: with a longer muzzle device that traps (at least some) gas, the firearm may function correctly by allowing enough gas thru the gas port, as the extra time (albeit small) the bullet spends in the can may be enough to get enough gasses necessary for reliable function.
