FN Non-Reciprocating Charging Handle Conversion FN SCAR 17S, 20S

The FN SCAR 17S/20S non-reciprocating charging handle conversion kit is a modularity upgrade designed for shooters who want to customize their SCAR rifle's ergonomics and operational flexibility. This kit replaces the factory reciprocating charging handle with a non-reciprocating system, giving you dual ambidextrous charging handles that stay put during fire—a major quality-of-life improvement for running any grip style, shooting position, or optic setup without interference. If you're invested in a SCAR platform and tired of workarounds around a moving handle, this conversion addresses a real friction point.

The kit centers on a new bolt carrier and an innovative charging handle sled, paired with two reversible, reversible charging handles that lock forward when the bolt closes. That static design means cleaner transitions between positions, easier access regardless of your dominant hand, and no surprises during rapid fire. The SCAR platform is already known for inherent accuracy and reliability—this upgrade simply removes one ergonomic limitation that aftermarket builders and end-users have complained about for years.

Important: Installing this kit on an FN SCAR 16S or 17S requires removing the front plate, a task that demands a qualified gunsmith to avoid damage. If you're working on a 20S or have professional armorer support available, that's less of a barrier. Either way, this is a genuine upgrade for serious SCAR owners who shoot enough to justify the conversion cost and labor.
