Myth Industries Super16 9mm FRT Kit

The Myth Industries Super16 9mm FRT Kit packages every part an AR-9 forced reset trigger build actually needs into one matched bundle. The kit ships the Super16 forced reset trigger, anti-walk pins, a KynShot 9MM H3 hydraulic buffer, and a Premium Black Nitride 9mm bolt carrier group whose rear blowback weight is already cut for FRT clearance. Forced reset triggers use the bolt carrier's rearward travel to mechanically push the trigger back into reset after each shot, which can produce much faster splits than a standard semi-auto pull.

The reason this kit exists is the AR-9 blowback problem. Direct-blowback 9mm carbines have no gas system; the bolt is driven straight back by case pressure, so AR-9 carriers carry a heavy tungsten or steel rear weight to slow the cycle. That rear weight is exactly where a forced reset trigger's reset lever needs room to work, and a stock 9mm BCG will foul the FRT. Builders have historically solved this by hand-cutting the carrier and hand-picking a stiffer buffer and spring, calibrating against a specific upper, ammunition, and trigger. The Super16 kit removes that step by shipping a BCG with the rear weight already cut and a KynShot hydraulic buffer that dampens the blowback impulse, so the trigger resets cleanly without a custom machining session.

The kit sits at the premium end of the FRT category at $469.97, but that price covers the trigger, the buffer, and the BCG as a single tuned system rather than three separately sourced parts. Myth Industries notes the kit may require gunsmithing for some AR-9 variants, so confirm fitment against your specific lower and upper before ordering. Forced reset trigger legality is volatile and state-specific, and the category is the subject of active patent litigation, so verify current federal, state, and local legality before purchase.
