Ok here is the setup: AAC 12.5 upper with brakeout mount and AAC 762SD N6. Lower has standard buffer spring and H2 buffer as recommended by AAC.
Ammo used is factory 115 Remington super and 220 sub
115 super with suppressor the gun runs great, unsuppressed it will run but not lock back on last round
220 subs short strokes like crazy with suppressor. Did not bother trying subs unsuppressed, no point in it.
Suggestions? Comments? Go with an underpowered buffer spring? Change out buffer weight up or down? Thanks
Under gassed!?!?!?

When I go to bed a law abiding citizen and wake a felon, by the stroke of the legislative pen, tyranny has arrived.

Re: Under gassed!?!?!?
As long as you don't have anything unusual, like an extra-power hammer spring, I would say call AAC and ask for an RMA number.
