SOT Micro-Jigs – Dual-Side 3rd-Hole Jig for AR-15 Lower Receivers (FFL & SOT only)

Enhance your lower-receiver machining capabilities with the SOT Micro-Jigs — a precision, hardened jig engineered to let you drill the 3rd hole on both sides of the lower using a standard hand drill. Unlike older jigs that require you to flip or use a drill press, this innovative design ensures symmetrical accuracy, simplifies workflow, and saves time.
