The Elftmann ELF-SE PRO Drop-In AR trigger with the PRO-LOCK retention system and FA Knob is engineered for shooters who demand absolute stability with fine tuned control, offered here with a straight trigger shoe in black at a 2.75 pound factory set pull weight. Elftmann Tactical built this unit to deliver a clean, repeatable break suitable for competition, tactical use, and precision AR builds. The straight shoe changes where your finger contacts the trigger and how the pull feels. For many shooters that geometry is the difference between good and excellent.
Trigger upgrades are the fastest route to better shooting on an AR. Nothing else you bolt on improves your groups as directly.
What the Elftmann ELF-SE PRO Drop-In Trigger Delivers
This is a self contained trigger module that installs in a standard AR lower receiver with no gunsmithing. The PRO-LOCK retention system securely anchors the module inside the receiver, eliminating movement under recoil or sustained fire, which combines the rigid feel of a fixed pin trigger with the convenience of a true drop in installation. No adhesives, proprietary pins, or permanent modifications are required.
The straight trigger shoe is the defining feature of this variant. A straight face gives a consistent, perpendicular finger contact regardless of where along the shoe you place your finger, which many competition shooters prefer for its predictability.
It suits precision rifle builders, three gun competitors, and anyone whose factory mil-spec trigger is holding back their accuracy.

Specifications and What They Mean at the Bench
The 2.75 pound pull weight is the headline number. That is light enough to eliminate the trigger as a source of movement while remaining heavy enough for a rifle used beyond a bench, which is why this weight has become a common choice for dual purpose builds. It arrives set from the factory rather than requiring you to tune it on arrival.
The FA Knob is where the PRO in the Elftmann ELF-SE PRO Drop-In name earns itself. It allows shooters to fine tune trigger pull characteristics to personal preference, so the same module can be adjusted for a competition rifle or a general purpose carbine without swapping hardware.
Installation, Safety Checks, and Care
Clear the rifle and verify it is unloaded, separate the upper from the lower, remove the existing trigger and hammer assembly, then seat the module and engage the PRO-LOCK system per the instructions. Because the module locks itself in place, there is no play to chase and no shims to fit.
Perform a full function check before live fire without exception. Confirm the trigger resets, that the hammer does not follow the bolt carrier forward, and that the safety selector blocks the trigger properly in the safe position. Repeat that check after any disassembly.
Give yourself time to adapt to the lighter break. A trigger this crisp will surprise you for the first few magazines if you are coming from a heavy factory unit, so start slow on paper before running speed drills.
Keep the module clean and use lubricant sparingly, since excess oil in a drop in unit collects carbon and grit. Wipe rather than flood, and inspect the retention hardware periodically. Our parts and upgrades collection carries the grips, stocks, and internals that complete a precision build.
Stable, adjustable, and genuinely crisp, the Elftmann ELF-SE PRO Drop-In trigger turns a competent rifle into an accurate one. Drop it in, function check it, and go earn the difference. Ships direct to your door, no FFL required.
