The task was not easy. The customer wanted a Sten Mk3 which could be disassembled like an MK2.
As you probably know the MK3 was the cheap version of the Sten family and was completely pinned to save costs; this meant that the tropps could not maintain and was designed to be left back and taken to maintenance facilities which could remove the pin and repair it.
The troops hated it and the customer did not like a gun which could not be serviced in house so he asked us to male a MK2 and make it look like an MK3.
So we decided to make a 2 piece rib which would end in line once you screwed in the front barrel nut (or sleeve).
If you look attentively you can see a very small cut in the front rib. The threads on the front barrel nut (sleeve) had to be treated with anti seize paste because the rib is straight when the front sleeve is fully torqued into the receiver.
Making the sleeve perfectly straight was a pain (the sleeve could fully torque left or right every time it was reassembled) but I think we did a good job. If you look attentively you can see a small cut in the front rib where the front rib aligns with the rear receiver rib.
This gun can be build in less than 2 months and is based on an Indianapolis Ordnance system.
The finish is KG Kote HK Black, baked hotter on purpose to make it lightly gloss like the original finish (but much better). Price is around $1800/2000 depending on features (the Indy Ordnance system bolt/barrel /receiver costs $500).
