Pls help troubleshoot failure to feed in XM15

A few squirts of Rem-Oil on the rails, cam, rings, bolt, bolt carrier and the buffer and the problem is resolved!

Thank you to all.

FYI Remoil evaporates over time. trust me.

Unless I'm mistaken, anything that is petroleum based is going to evaporate over time. I've found Remoil to be really thin and it seems to just fly off. Frequent relubing is required. If you stick with a synthetic, it will last longer under fire.
