Sterling Mk4/L2A3 trigger en bloc

Is this the bushing modification?

It looks like the bushing is welded in.

Yes, but not a 'Normal' Brit repair. We would have brazed the bush in. Much neater!

Thanks. It sounds like I should just replace the ‘butt pivot’ with a newly made one. We call it a ‘trunnion’ over here. Not difficult to make. I could do away with the pins and use e-clips, like on the Canadian C1 SMG.

Yes indeed! Trunnion is more correct! don't forget, ALL projections/Fittings on the Sterling Receiver. Were electrically heated & brazed on in the factory. They were aligned on a jig to hold them correctly in place prior to 'fusing' on the receiver tube.

For the butt especially, it is CRITICAL to align the Trunnion properly. Or the Butt wont line up with the butt holding lugs recesses. On the inside of the Return spring end cap, When opened up!....
