Ops-Core
Rifle-rated FAST helmet system that covers 7.62x39 mild steel core, 7.62x51 M80 ball, and 5.56 M193 at 2.59 lb shell weight in size large.
The Ops-Core FAST RF1 is the first helmet in the FAST line rated against rifle rounds. It stops 7.62x39 mild steel core, M80 ball (7.62x51 NATO), and M193 ball (5.56x45) projectiles in addition to the standard handgun and fragmentation threat spectrum a FAST SF or Maritime covers.
The performance number that matters: 2.59 lb shell weight in size large. That is roughly 1.3 lb heavier than the bare FAST SF shell, but still unusually light for the rifle-threat coverage. For a typical setup with NVG, mount, counterweight, and ARC-rail headset, the all-up loaded weight lands around 5.5-6 lb, which is wearable for extended operations but not casual.
The FAST RF1 retains the standard FAST interface with PowerPath ARC accessory rails and an MBS shroud, so Wilcox/Norotos NVG mounts, Princeton Tec/S&S helmet lights, and compatible rail-mounted headsets carry over cleanly. Gentex publishes a 6-week lead time on single orders, 8-12 weeks for multiples. This helmet is appropriate when the threat model genuinely includes rifle rounds.
