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.

CALIFORNIA BUYERS: Please check with your transferring dealer before ordering. Many CA dealers are unwilling to process lower receiver transfers.

Important Warranty Note: 

If you intend to register your Quarter Circle 10 firearm as an NFA weapon, test it thoroughly before doing so in a Title 1 Configuration.  Once you Form 1 or Form 2 it, you are legally the manufacturer, and we cannot service the firearm.  Should your firearm require warranty replacement we can only replace it with a Title I receiver and we are not responsible for tax stamps or NFA fees.
