First things first, the new operating handle. Although the one provided with the ASG Sten is close enough to correct, I preferred the small, rounded operating knob as it is less likely to catch on clothing. For this build it is perfectly possible to use the original handle.
In order to make the gun ‘safe’, the operating handle is pulled a little further back than the regular ‘cocked’ position. It is then pushed up into the lug above the channel where it usually runs when firing. On the real steel Sten, this simply stops the bolt from being able to reciprocate and therefore ‘safe’. In reality this was a far from perfect system and these guns still had a reputation for going off when dropped.
As this is an AEG, this safety mechanism uses a microswitch to control current flow.
The operating handle will be oil blacked for use, but it wouldn’t have shown up for the photos here to demonstrate so I left it unfinished.
