The Timney AR-10 Skeletonized Trigger (Timney part number 671) is a small-pin, drop-in trigger factory set to a non-adjustable 4-pound pull, built for semi-automatic AR-10 platform rifles. Installation uses the rifle’s original hammer and trigger pins, and the skeletonized trigger shoe cuts weight while keeping a solid, positive feel under the finger. Because the pull weight is fixed, there is nothing to tune after installation, keeping the swap straightforward for builders who want a crisper, lighter trigger without a tuning process.
