STEN MK2 SEMI AUTO TUBE BLANK. This design works with our standard horizontal and vertical feed semi auto bolt kits. This rough cut tube WILL require machining on a lathe to print (included), applying the template (included) with glue (not included), and then cutting out the slots and ports. This is a NON-RETURNABLE item and COPYRIGHTED for single use only, all sales final.
This tube blank must be cut to length and both ends must be bored out. All dimensions are listed on the template.
