All of Elftmann Tactical’s drop-in AR triggers (AR10/AR15/AR9) now include a very slick new feature: an “incremental adjustment knob.” This knob, which can be turned by hand or with a flat tool/coin, adjusts the trigger pull weight up or down click by click.
Break weight range on ELF’s triggers varies depending on the model — Match, Service, 3-Gun, Pro, etc. — but most have 2-1/4 to 3 pounds of adjustment range.
This is a neat adjustment system that’s not only handier than a hidden set screw, which requires a specific tool, but it allows for repeatable adjustment steps that are easier to hit than an infinitely-adjustable screw (e.g. set your triggers “four clicks from the lightest setting”).
Should the adjustment knob back out for some reason — though ELF assures that the nifty spring detent will not allow the knob to turn unless the owner intentionally turns it — the trigger simply defaults to its lightest pull weight setting.
TTAG has the trigger seen in these photos in for review. As I’ve extensively shot the ELF triggers in the past (and included one in this very comprehensive drop-in AR trigger roundup test) I won’t be doing a full review on it, but I’ll shoot a bunch of rounds through it while testing the pull weight adjustment mechanism for function and reliability.
