This is a semiautomatic bolt system for the British Lanchester. This system is designed around our (LancSAT) and will accept an original extractor and cocking handle for an authentic look. This kit includes the following high quality American made parts: a semiauto bolt, standard AR-15 firing pin, roll pin, firing pin spring, bolt stop, guide rods, 2 sets of springs, and assembly instructions.

Please note: Most Lanchester trigger groups do not have a selector switch. The trigger group will have to be modified and a disconnector installed that will function similar to the STEN trigger groups.
This design is based on our ATF approved STEN MK3 model. Other US made parts may be needed to be compliant with GCA 18 U.S.C. 922r.
