Quarter Circle 10 Lowers: AR-15 + Glock Magazines

    Glock Lower

    Quarter Circle 10 is now producing AR lowers that accept Glock magazines. The lowers can be had as a small- or larger-frame receiver. The smalls are for the 9mm, 40 S&W, 357 SIG and 45 GAP calibers, while the large frames handle 10mm and 45 ACP.

    All of the lowers have a last-round bolt hold open, have a Glock feed ramp and are made of 7075-T6 aluminum. The lowers come with Glock magazine releases, and no modifications to the magazines are needed.

    MSRP is $274.95 for the small-frame receivers. Large-frame receivers have not gone on sale yet. The company also sells 9mm and 40 S&W bolts and barrels.

    Hat tip to Cymond for the information.
