Overview

This is the same 3DP MAC FRT geometry as the 316 stainless unit, printed in carbon-fiber-reinforced PET and sold six to a pack for $40. The economics are the point: MAC-pattern hosts vary so widely between Cobray and MasterPiece Arms that no vendor guarantees fitment, and 3DP says outright that tolerances differ severely between makes and models. $40 buys you six chances to find out whether the geometry works in your gun before committing to steel.

Printed polymer is a wear part. The open-source Twitch design that competes with it burned through PLA test triggers in as few as 17 rounds; PET-CF is considerably tougher than PLA, but it is still plastic riding against a steel bolt. Buy the multi-pack because you will go through them, and step up to the stainless version once you know the trigger cycles in your host.

Terms match the steel unit: beta batch, sold for R&D, all sales final, not a drop-in part. Fitting and tuning are expected.

Key Features

  • Carbon-fiber-reinforced PET for strength and heat resistance over plain PLA
  • Six triggers per pack; a 12-pack is available for $65
  • Same geometry as the 3DP 316 stainless MAC FRT
  • Fits MAC-10 / MAC-11, Cobray, and MPA Defender hosts
  • Cheapest way to validate fitment on an unusual MAC host
  • One round per trigger function; semi-automatic operation retained

Pros

  • +$40 for six triggers, the lowest cost of entry in the category
  • +Multi-pack matches the reality that printed FRTs are consumables
  • +Same proven geometry as 3DP's steel unit, so it doubles as a fitment test
  • +PET-CF is meaningfully tougher than the PLA the Twitch design was prototyped in

Cons

  • Printed polymer wears against the steel bolt and will need replacement
  • Beta part with all sales final and no refunds
  • Not a drop-in; expect fitting and tuning
