I think the OP wants to know
Gas System or Piston System?
I have a factory 10.5" LMT upper with a standard DI system. It runs like a top with quality ammo.
It runs perfectly when plinking with wolf, but if it gets hot, like when running it in a carbine course, it can get sticky with wolf.
An ammo change to brass cased stuff ends the problem.
I'm told LMT uses a gas port appropriate for 5.56x45 ammo, so its a bit under gassed when running cheap weak stuff.
It also works great with my .22 conversion kit and my friend's M16 lower.
Its a little loud and it throws a bit of a flame with the brake on it.
