1045 receiver and 10mm

The 1045 lower receiver and 1045 receiver set is designed to accept 10mm Glock double stack magazines. We do not currently offer a complete firearm chamber in 10mm or any other 10mm components. We do not recommend building a 10mm in a blowback configuration at this time due to concerns with 3rd party bolt carriers and barrels. A direct impingement (DI) 10mm system is possible to build, although, we do not have any recommended sources available at this time.
