Semi automatic bolt kit for the SWEDISH K M45

New and improved design with "J" hook safety and heavier bolt for easier cycling with a 16" barrel. Not all parts kits have the selector switch that makes a semi auto build much easier. If your trigger group does not have the selector switch, you will have to modify it.

This kit comes with a build guide and includes:a semi auto bolt, hammer, firing pin, retaining pin, firing pin spring, two sets of springs, guide rods, bolt stop, ejector, and two rivets for the end cap locking lug.

You may need additional USA made parts to be 922R compliant. A barrel extension does not come with this kit. You will have to obtain a 16" barrel or barrel extension, or submit the required paperwork to the ATF before beginning. This design has been approved by the ATF.

Note: To be 922R compliant, our sample to the ATF included a new 16" barrel and pistol grips (not included in this kit). 

Note: MIG or TIG welding is required for assembly.
