▍Main Features

■ Compatible with M14 reverse-thread standard
You can attach a wide variety of commercially available muzzle accessories, such as 14mm reverse-thread (CCW) specification silencers, tracers, and flash hiders.

■ High-precision design machined from POM
Uses high-performance POM (polyacetal) resin, also used in machine parts, as the material. High-precision machining achieves dimensional accuracy and a stable fit.

■ Lightweight and highly durable
POM is lightweight and offers excellent wear resistance, impact resistance, and self-lubricating properties, ensuring sufficient strength while minimizing weight gain. Its ease of handling, unique to resin, is also a feature.

■ Through-hole structure
The through-hole design with an inner diameter of 8.5mm or larger prevents interference with BBs and the inner barrel. It also minimizes the impact on firing performance when installing a silencer or tracer.


▍Overall Review
This is a high-precision silencer adapter that converts to the 14mm reverse-thread standard without compromising the stock appearance. The lightweight POM machined structure combines practicality and durability. It is a recommended custom part for users who want to enhance the expandability of the S&T ST870.
