0940 receiver and .357 SIG
The 0940 lower receiver and 0940 receiver set is designed to accept .357 SIG/Glock double stack magazines. We currently do not offer a complete firearm chambered in .357 SIG or any other .357 SIG components. At this time we are not aware of any other manufacturer making barrels or bolt carrier groups chambered in .357 SIG for the AR platform. If you are interested in building a firearm in .357 SIG we recommend contacting your local gunsmith to discuss your options.
