Thought about the 38 case and ball bearing trick,grinding the BAS seem to me a bad idea,
had to be a better way,searching the net I came across a bolt lift mod that actually makes sense,
the parts consist of 2 thrust washers and 6 ball bearing encased in nylon,a perfect fit in the bolt body,
the BAS spacer you have to make yourself.
Received the bearing kit,machined a spacer,installed, now I can open the bolt with the back of my hand
with just a small amount of resistance and smooth as silk.
Of all the bolt lift mods I've seen,you can't beat the BSA riding on 6 ball bearings and no mod to the BAS
to boot.
