Looking to purchase a semi Wise Lite Sterling firing pin, Wise Lite is out of stock, any options? Thanks in advance!
Thanks, Wise Lite used the original SMG firing pins?
Wise lite claimed the issue was due to heat treat on the pins but that isn't the case in my experience.
I have converted 38 mk4 bolts to semi auto and reworked a number of wiselite bolts as well.
We make our own striker assemblies in house and I have only ever broken 1 firing pin. In my case, it was due to the tip diameter being too large.
Most wiselite pins fail because the hole in the bolt face is not concentric with the striker channel.
Another common issue is surface roughness in the striker channel. Wiselite drilled them right to size with a standard twist drill leaving behind a rough surface finish which causes a lot of drag on the striker assembly. We drill the channel undersize, bore them to finish diameter with a 3/8 endmill and then finish them with a dingle ball hone. This ensures the striker will glide through the channel with the least resistance.
Wiselite did what was necessary to meet the goal for production cost of a $400 carbine. From that perspective, they did quite well. From the perspective of an owner who enjoys shooting one of these now expensive and collectible weapons, it can be quite frustrating.

Any good reason to go with titanium over stainless?
Where could one find one of these very-nicely machined bolts, if one were so inclined?
