It features an impact resistant construction meaning it won't crack or break when dropped. The ETS Magazine is creep resistant as well, meaning the feed lips and body won't spread when being stored long term even when fully loaded. The ETS magazine is resistant to harsh chemicals including heat, cold, and UV resistant, so it won't become brittle over time even when exposed to harsh environments.
