The Quarter Circle 10 Glock style bolt assembly uses a blowback design that works with Glock magazines. These bolts are made to exacting tolerances and feature a patent pending extractor for the best reliability possible. This bolt was designed from the ground up and is not a modified part like many other pistol caliber AR style parts. QC10 has proven their products over time. When it comes to PCC parts there's a reason why one of the first names you hear is Quarter Circle 10. Made For - Not Modified.
