With that ammo supply anyone should be able to get behind a Tac-Con 3MR trigger and really race it.
The 3MR trigger is a non-NFA trigger that partially resets when the bolt cycles. If you get the timing down you can get some “faux-auto” action out of it. It is a fast trigger, but it takes practice (and ammo) to master it.
They are pretty expensive, but they’re the next best thing to a fun button this side of a SlideFire stock.
