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.

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)

  1. High quality review by Ace on 2/26/2017

    My small frame Glock lower worked great, the only drawback was the lrbho, it doesn't work every time, unless you're hand cycling. I built mine with a quality lpk, aero upper w/o forward assist, kaw valley 8.5" barrel/Bcg/7.5oz buffet kit. 150 rounds of mixed cheap ammo, target, and defense rounds on first day with no fte or ftf. I'm in love with my new Glock-15. Thanks QC10!
