The Short Stepper is a drop-in fidget assembly for AR-15 platforms. It mechanically forces the trigger to reset after each shot when properly assembled and tuned. This is a drop-in device that requires assembly and per-build lever tuning — it is not a trigger or a device to change trigger pull weight.
What’s included:
Short Stepper housing — 316 stainless steel
Short Stepper Ar-15 lever — 316 stainless steel
Short Stepper Ar-9 lever — 316 stainless steel
Short Stepper timing gear — 316 stainless steel
Three-position skeletonized selector – raw 316 stainless steel
5 mm retention pin
Fitment & compatibility
Designed to install on top of OEM safety selectors.
Compatible with our TURD, FART, or KABUTO three-position safety selectors for three-position operation.
Works with most AR-15 lowers; however, dimensional variance between lowers/parts means tuning is required for correct timing and reliable function.
Assembly & tuning (important)
Ships as an assembly kit that must be assembled and the lever tuned per build to achieve proper reset timing.
Basic mechanical skill and proper tools are required. If you’re unsure, have a competent gunsmith install and tune the unit.
Housing may need polished as well as holes may need further tapping if too rough.
