Any orders containing lower receivers require a verified FFL dealer to make the transfer.

Lower receivers will not be shipped until QC10 has your dealer’s license on file.

Please contact your desired dealer about sending us a copy of their license.

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.

Requires a Glock Style Bolt for use with Glock magazines (will NOT work with bolts designed for use with M3 “Grease Gun” magazines)
