Serious bummer
Speaking of ball detents.
I made a huge mistake when trying to un-screw and clean my ball detents on my impulse. The first one (on the eye-side) went off fairly easy and I expected the other one to come off just as easy. But no, I completely destroyed the housing on the screw, rendering it useless...Now I'll have to un-screw it with some other, really strong, tool
Just a warning for other recent impy-owners.
