OPS-CORE: FAST and Sentry helmet families, ballistic and bump shells, retention and pad kits, rails, shrouds, and accessories. Ballistic products are restricted to verified professional purchasers.

About OPS-CORE

OPS-CORE builds head-borne systems used across US and allied special operations, law enforcement tactical teams, and air crews. The FAST helmet family — high-cut ballistic and bump shells — set the template for modern helmet geometry, and the Sentry line extends it to patrol and duty use.

We carry the helmet shells we are authorized to sell along with the parts that keep them serviceable: retention systems, occ-dial and pad upgrades, ARC and Wing-Loc rails, NVG shrouds, counterweight kits, mandibles, visors, and mounting hardware. Head-borne kit is rarely bought once — most of our OPS-CORE business is replacement pads, retention, and rail accessories for helmets already in service.

Ballistic products are sold to verified professional and agency purchasers only. Deliberate Dynamics is an authorized dealer. Everything ships factory-new with full manufacturer warranty — no gray-market, closeout, or refurbished stock.

Common questions

Who can buy OPS-CORE ballistic helmets?
Ballistic shells are restricted to verified military, law enforcement, government, and qualified professional purchasers. Bump helmets and accessories are generally unrestricted. If a listing is restricted, we will verify eligibility before releasing the order.
How do I size an OPS-CORE FAST helmet?
Measure head circumference just above the brow and match it to the size range in the product specifications. Pad thickness adjusts fit within a shell size — if you are between sizes, contact us before ordering.

Our 25% GOVX discount currently covers Arc'teryx and Salomon only. For this brand, agency, unit, and department purchases are quoted directly — request a quote and we will price the order against your requirement.
