Gasflow/taperlock. Suppressor thread tightens automatically when shooting. Fast revolving gases inside the suppressors creates rotational force keeping the suppressor firmly seated. Taper mount at the front of the Silent Steel QD muzzle device together with heat resistant o-ring locks and effectively seals the suppressor keeping the mounting surfaces and thread clean from carbon buildup.

Minimal and repeatable point of impact change. Streamer’s use direct thread mount with taper lock. This design is least affected with POI shift because the suppressor indexes at the same point when mounted and remounted every time. Streamer’s design inside the suppressor is symmetrical. The bullet travelling through the suppressor is affected by gas pressure symmetrically from all directions which keeps the bullet trajectory always the same. In most cases point of impact shift is 1-4 cm and straight down (100m).
