Far from perfect, but we didn't need perfect, we needed a 9mm SMG to aerate boxheads with. The Mk.II was a cracking design with a lot going for it. I could assemble & strip a Mk.II at the age of 17 better than most folk that used them in anger. Used to have a lot of fun with these in the gun club back in about '82 or so, most club shooters would have a Sten or two as a range toy.usually a Mk.II or Mk.III (less common to see) Here's a video for reference.ĪLWAYS worth recalling with ALL the Sten models - the magazines can be a PITA - as they are one of the design weaknesses, having a double column stack but single feed. The inner mandrel can also be used to expand the mag body to the correct dimensions (if the mag body is a little crushed, you can spread it back out with the inner mandrel). Just for reference, the inner mandrel would support the disassembled mag body while using the top mandrel and the gauge goes over the top of the mag with the dual function of verifying the correct feed angle and overall spread of the feed lips. I was fortunate enough to procure a set of arsenal repair tools. You would basically put this over the top of the magazine body then hammer the top of the mandrel a few times to reform the feed lips. I noticed that BRP has the top mandrel available Here.
#STEN MK II ASSEMBLY FULL#
I understand the full set of magazine repair tools (inner mandrel, top mandrel, and gauge) have become pretty rare on the open market. There are magazine repair tools that can reshape the feed lips on the mag body back to the correct dimensions. The feed lips on the mags can spread open and change the feed angle (leading to the noted/most common reliability problems). Extremely forgiving, as long as you don't pour so much heat into the tube that you warp it.Īs long as you have good mags, the Sten can be very reliable. How forgiving is the welding? I figure i would pickup a HF Mig setup and maybe practice a bit on some scrap before actually trying on the real receiver. So i guess it starts with the parts kit, cut off the old receiver with a dremel or whatever, and cut the old front sight post and ejector off? Yes.Īs far as cutting and welding the new receiver(i figure Indianapolis ordnance), you basically tack it to the lower original hunk and weld the end cap on? Yes, basically. I would use Indianapolis ordnance for the 8" barrel, Semi-auto kit and their receiver. How forgiving is the welding? I figure i would pickup a HF Mig setup and maybe practice a bit on some scrap before actually trying on the real receiver.Īny good guides to this or advice?.i'm getting bored with assembling Ar's and figure i would try something different that takes some actual building rather then just assembly. So i guess it starts with the parts kit, cut off the old receiver with a dremel or whatever, and cut the old front sight post and ejector off?Īs far as cutting and welding the new receiver(i figure Indianapolis ordnance), you basically tack it to the lower original hunk and weld the end cap on? VIagazine springMaterial: Music wire 1.5mm dia.So i want to build a Sten MK II, it seems at face value to be simple but not as cheap as it leads on when you add the semi auto kit. Thus asimple, flat follower with a dummy round solderedand/or screwed to it will replace a complicated stamping. To make a follower in a simpler wayis to follow the Degtyarev DP LAIG approach - usinga dummy round as the last one in the magazine. Note: The *magazine follower is a compks stamping made ona progressive die.
