MK12 problem

[KACstealth]

so i purchased a MK12 on the EE here and I took it shooting for the first time today.
It was short stroking and would not feed a round after i fired the weapon. What do i need to do in regards to trouble shooting
I want it to be able to shoot any sort of ammo i throw at it

THanks in advance for the help

A navy seal friend of mine told me they like to run wet. Lube should fix it.

Re: MK12 problem

Purchased new, factory built? Or used, something someone assembled? If new it may be tight, or full of preservative, clean and lube well. If built the buffer could be on the heavy side, the 18" barrel with a rifle length gas system doesn't have the dwell time of a 20" it will likely be a little more sensitive, but should function on just about any factory loading.
