This is our standard slim barrel blank deep chambered for 9mm Luger. This allows you to build a 16" barrel for a STEN or other semi-auto carbine or even bolt action rifle like the Spanish Destroyer without having to buy a chamber reamer. As you can see the chamber has been deep set to allow you to bring the rear of the barrel to the precise place needed for your application (This is how barrel comes). The two examples shown on the right give you an idea of how much needs to be removed for a STEN on the Left or the MP-28/Lancaster on the right. If your application required more than the 0.800" diameter you can machine a collar, an easy job with the lathe, and make what ever size needed for your job. All without the expense of buying a chambering reamer.
