Had two Walkers that were unsafe.
Both had been messed with by prev owner, and left in unsafe condition (one unknown, the other was sold with the words "great trigger, close the bolt slow and easy".

I swapped out springs and made them just as light, and they were safe.

Idiots and firearms and never a good mix. Thankfully many of such stupidity stay away from guns and just make babies, vote, look at cell while driving etc.
