STEN MK5 SEMI AUTO tube that can work with our standard horizontal feed bolt (MK5SAK) or our vertical feed bolt (MK5VSAK). The high quality template is CAD drawn and is glued to aerospace grade 4130 DOM tubing. The front of the tube is bored out to accept the original front barrel bushing or our reproduction (MK5BN). You will need a dremmel tool or milling machine and a welder to assemble. This design has been classified by the ATF as a firearm and not a machinegun. This is NOT a receiver and does not require a FFL for purchase.
Due to demand, Sten tubes are limited to one per customer per 6 months until noted otherwise. Thank you.
