Frequently Asked Questions

Can I upgrade my old FN SCAR 17 to the new Non-Reciprocating Charging Handle (NRCH) system?

No, you cannot factory-upgrade an older FN SCAR 17 to the NRCH system. The new NRCH requires specific receiver modifications, including a 'shelf' and a unique pin, which are absent in older Belgian and early US-made models.

What is the main advantage of the FN SCAR 17 NRCH?

The primary advantage of the NRCH system is the elimination of the reciprocating charging handle. This prevents 'SCAR thumb' injuries and allows for more flexible grip techniques during operation, as the handle remains stationary during live fire.

How does the NRCH system work on the FN SCAR 17?

The NRCH system utilizes a 'shuttle' or 'sled' mechanism that connects the charging handle to the bolt carrier only when manually cycled. During live fire, a pin in the receiver disengages this connection, keeping the handle stationary.

What is the price of the new FN SCAR 17 NRCH?

The Manufacturer's Suggested Retail Price (MSRP) for the new FN SCAR 17 NRCH has increased to approximately $3,500 or more, reflecting its premium features and construction.
