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 Colt SMG magazines)
