Semi automatic bolt kit for the Sten MK2
This closed bolt system works extremely well and eliminates the problems of kits offered by other companies. The bolt in this kit is machined to allow feeding from a vertically mounted magazine housing similar to the MP-40 and the MP-3008.
You will need this kit, one of our tubes (MK2SAT), and an original Mk2 parts kit in order to build a legal semi automatic firearm.
This kit comes with a build guide and includes the following parts: vertical feed semi auto bolt, cocking handle, standard AR-15 firing pin, roll pin, firing pin spring, bolt stop, guide rods, rod retainer, and 2 sets of springs.
You may need additional USA made parts to be 922R compliant. This design is based on our ATF approved STEN MK3 model.
Note: Two small parts require welding.
