Product description

This lower is a stripped lower and will require a Mil-Spec Lower Parts Kit to complete. All proprietary parts will be included (last round bolt hold open, magazine catch, ejector etc)

Requires a Glock Style Bolt for use with Glock magazines (will NOT work with bolts designed for use with Colt SMG magazines)

For proper function with calibers other than 9MM, QC10 recommends pairing the GSF lower with an enlarged ejection-port upper, like the QC10 Pistol MUR.
