Ark Liu shows a Red Dot Sight from TBRM for this overview video... "How will you react when your gas and BB bomb manufacturers start making inner red dots? Yes, TBRM will debut their new inner red dots at MOA before the end of 2024, and there will be at least 6 more options. As a channel that has benefited from TBRM for a long time, we also got the test samples as soon as possible. In order to be different from the general unboxing and running account, this time the product was directly and unceremoniously put through two tests: 1. Waterproof* 2. Shockproof*. The results very well show that the products brought by TBRM are enough for players to use in normal and more demanding environments, bringing a new choice to players."
