The Elftmann ELF APEX PRO SE is a drop in AR trigger that delivers competition grade performance with two features that set it apart, namely the PRO-LOCK retention system and the Flat Adjustable FA knob. This version wears a curved trigger shoe finished in eye catching red, and it breaks at a crisp factory set 2.75 pounds. That is light enough for serious speed work yet consistent enough to trust shot after shot.
Built for shooters chasing the clock
Competitors are the obvious audience. A 2.75 pound break with no creep lets you press through a stage without fighting the trigger, and consistency is what turns a good run into a repeatable one.
It is equally at home in the hands of an enthusiast who simply wants speed, precision and a premium fire control upgrade without compromises. You do not need a match schedule to appreciate a trigger that breaks the same way every time.
What PRO-LOCK and the FA knob do for the Elftmann ELF APEX PRO SE
The proprietary PRO-LOCK system clamps the self contained trigger module firmly inside the lower receiver, eliminating the movement some drop in units develop under recoil or extended firing schedules. You get fixed pin stability with true drop in convenience.
Nothing about the process is permanent. There are no adhesives, no proprietary pins and no modifications to your lower, so the receiver stays standard and the trigger can move to another rifle later.
The integrated FA knob layers user control on top, giving you adjustability to fine tune the trigger to your own preference rather than living with a single factory answer.

Specifications in the real world
Fitment is the AR platform generally, and the module format means it behaves the same in every lower it goes into. A shooter running several rifles can standardize trigger feel across the whole rack, which pays off the moment you switch guns mid match.
The red shoe is not just cosmetic on a competition gun. It makes the trigger instantly identifiable when you are checking someone else’s rifle at the safe table, and it tells you at a glance which of your lowers has the Elftmann ELF APEX PRO SE fitted.
A light trigger is only an advantage if it is also predictable, which is where the factory setting earns its keep. Elftmann Tactical sets the weight in house rather than leaving it to the buyer, so the break is the same on the first press as the ten thousandth.
That predictability is what lets a shooter build speed safely. You learn one trigger and stop adjusting to it, which is the entire argument for putting the same Elftmann ELF APEX PRO SE module in every rifle you compete with.
Installation, function checks and care
Installation is the standard routine. Clear the rifle, separate the receivers, pull the factory group, seat the module, run the pins and lock it down. Most shooters have this done inside ten minutes with a punch and a hammer.
Function check on the empty gun every single time. Confirm the safety blocks the trigger, confirm the hammer does not follow the carrier home and listen for a positive reset.
Keep the housing clean of heavy carbon and put a light oil on the pins at each cleaning. When you are ready to keep improving the rifle, our upgrade parts range has the rest of the components worth your money.
Speed, precision and a shoe that stands out in any lower, with no compromises in how it installs. Ships direct to your door, no FFL required.
